How Much Does Infrared Asphalt Repair Cost?

Infrared asphalt repair costs $2 to $6 per square foot in Canada, with most commercial parking lot repairs ranging from $300 to $1,500 per patch depending on size, depth, and accessibility. A typical day of infrared repairs on a commercial property covers 10 to 20 patches and runs $2,500 to $5,000, making it 30% to 50% cheaper than traditional cut-and-replace methods.

What does infrared asphalt repair cost per square foot?

Infrared asphalt repair typically costs $2 to $6 per square foot for commercial properties in Canada. A small pothole repair of 10 to 20 square feet runs $100 to $300, while a larger area of 100 square feet or more costs $400 to $1,000. Most contractors offer day-rate pricing for commercial clients with multiple patches, which brings the per-repair cost down significantly compared to one-off jobs.

The cost varies by province. Alberta and British Columbia tend to run higher due to labour rates, fuel costs, and shorter repair seasons. Saskatchewan and Manitoba are typically on the lower end. Most contractors require a minimum charge of $500 to $1,000 to cover mobilization, which means small single-patch jobs pay a premium.

How does infrared repair compare to traditional patching?

Infrared repair costs 30% to 50% less than traditional cut-and-replace patching for comparable repairs. A life cycle cost analysis conducted by Rutgers University for the New Jersey Department of Transportation found that the infrared method can be more cost-effective than spray injection for winter pothole patching, and for permanent repairs, infrared can be more cost-effective than the standard throw-and-roll method as well. The study compared material costs across methods: hot-mix asphalt used in infrared repairs costs approximately $84 per ton, compared to $110 per ton for bulk cold mix and $232 per ton for bagged cold patch.

The cost savings come from three areas. Material costs drop because infrared recycling reuses the existing asphalt in place, with only a small amount of new hot-mix and rejuvenating agent added. Labour costs are lower because the infrared method needs at least two workers operating the heating machine and then placing and compacting the patch, compared to four workers for semi-permanent cut-and-replace procedures. Disposal costs are eliminated entirely since no material leaves the site.

Time savings also translate to cost savings for property managers. A typical infrared repair takes 20 to 30 minutes from start to finish, compared to several hours for a traditional patch. This means less time blocking parking spaces, less traffic control, and less disruption to tenants and customers.

How does infrared asphalt repair work?

Infrared repair uses electromagnetic radiation to heat existing asphalt to a workable temperature without burning the material. According to KM International's technical specifications, the infrared wavelength energizes the first object it comes in contact with, softening the bituminous surface. Average heating times vary from 7 to 10 minutes depending on pavement design, age of asphalt, ambient temperature, and wind conditions. The equipment heats areas up to 40 square feet at a time using a ceramic refractory blanket with output up to 700,000 BTU.

The repair process follows a specific sequence documented in KM International's training procedures: heat the damaged area, rake the softened asphalt, apply rejuvenating agent, add new hot-mix asphalt, lute the surface level, and compact. Rejuvenators replace the maltenes (the light oils of the asphalt cement) that oxidize out of the material over its lifetime, restoring the binder's flexibility.

The thermal bond is the key advantage. As Asphalt Magazine describes it, the heated existing asphalt bonds with the new material when reheated, eliminating the "cold joint" that forms in traditional patches. Cold joints are seams between old and new asphalt where water infiltrates and causes the patch to fail. Infrared repairs fuse the materials together, which is why infrared patches typically last longer than traditional cold patches.

What factors affect the cost of infrared repair?

Several factors determine the final price of an infrared repair project. Patch size is the biggest variable, as larger patches take more heating time and more new material. KM International's specifications note that heating time depends primarily on the quality of the existing road surface, with variables including pavement design, age of asphalt, ambient air temperature, and wind speed all affecting the process.

The condition of the base layer is critical. Asphalt Magazine's technical overview warns that subgrade failures that are not repaired will only lead to future failure of the surface grade. For example, alligator cracking will look like it patched well using a surface-only repair, but it will quickly fail again because the problem is below the surface. In those cases, a full-depth repair with base reconstruction is the correct approach, not infrared.

Moisture is another factor. Water in the asphalt must be evaporated during heating, and during that evaporation the heat could quickly become excessive and damage areas of the asphalt while a more porous section remains wet. Contractors avoid infrared repairs during or immediately after rain for this reason.

The number of patches in a single visit drives per-unit cost down, which is why day-rate pricing works well for property managers with multiple repair areas.

When is infrared repair not the right choice?

Infrared repair is not suitable for every situation. Full-depth failures where the base layer has collapsed require excavation and base reconstruction that infrared cannot address. The NJDOT/Rutgers study notes that infrared heating can only transfer heat from the surface to sublayers through conduction, with depth of heat penetration less than 5 cm. Damage below that depth requires a different repair method.

Alligator cracking covering more than 25% to 30% of the lot surface indicates the pavement has reached end of life and needs resurfacing or replacement, not patching. Drainage problems that cause water to pool and undermine the base need to be solved before any surface repair makes sense.

For commercial property managers, the rule of thumb is straightforward. If the lot is generally in good condition with isolated problem areas like potholes, utility cuts, or localized cracking, infrared is the most cost-effective repair. If the lot has widespread deterioration, the money is better spent on resurfacing or replacement.

How long does an infrared asphalt repair last?

Infrared repairs typically last longer than traditional cold patches in commercial parking lots. Research from the NJDOT study documents average surviving life data for different material-procedure combinations, showing that heating methods produce more durable repairs than cold patching because preheating increases compaction degree and density, reducing air void content and water permeability.

The longevity of an infrared repair depends on the quality of the existing asphalt, proper compaction during the repair, and the condition of the base layer underneath. Patch preparation is critical: once the old material has been heated and removed, the edges should be squared off and tapered to allow for more surface area and ensure a good bond between new and old areas.

Regular maintenance extends the life of any repair. Sealcoating the repaired area as part of a lot-wide sealcoating program every 2 to 3 years protects the patch from UV degradation and water infiltration. The Federation of Canadian Municipalities' InfraGuide recognizes infrared heating as an established preventive maintenance method for municipal roads.

Is infrared repair available year-round?

Infrared repairs can be performed in a wider range of temperatures than traditional methods because the heater warms the existing surface. However, the NJDOT/Rutgers study found that since infrared radiation cannot penetrate the pavement directly and generate heat inside the pavement structure, time consumption can be considerable especially in winter.

Both wind and ambient temperature largely affect heating times as well as the time the material remains workable during the repair. In Alberta and western Canada, the optimal season is April through November, though some contractors operate year-round for emergency repairs with adjusted heating times.

The bottom line

For most commercial properties in western Canada, infrared asphalt repair costs $2 to $6 per square foot and saves 30% to 50% compared to traditional methods. The technology works best for isolated damage on lots that are otherwise in good condition. For properties with multiple repair areas, day-rate pricing ($2,500 to $5,000 per day) is the most cost-effective approach, covering 10 to 20 patches in a single visit with minimal disruption to parking and traffic flow.

Frequently Asked Questions

How much does infrared asphalt repair cost in Canada? Infrared asphalt repair costs $2 to $6 per square foot in Canada. A typical commercial parking lot repair of 50 to 100 square feet runs $200 to $600. Day-rate pricing for multiple patches ranges from $2,500 to $5,000.

Is infrared repair cheaper than traditional asphalt patching? Yes. Infrared repair costs 30% to 50% less than traditional cut-and-replace patching because it recycles existing asphalt in place, requires a smaller crew (two workers vs four), and eliminates disposal costs. A Rutgers University study for NJDOT confirmed infrared is more cost-effective than throw-and-roll for permanent repairs.

How long does an infrared asphalt repair last? Infrared repairs last significantly longer than cold patches because the thermal bond eliminates cold joints where water typically causes premature failure. Longevity depends on base condition, proper compaction, and ongoing maintenance like sealcoating.

Can infrared repair fix any asphalt problem? No. Infrared works best for surface-level damage like potholes, utility cuts, and localized cracking where the base layer is still intact. Research shows heat penetration is limited to about 5 cm depth. Full-depth failures, widespread alligator cracking, and drainage issues require different repair methods.

What time of year can infrared repairs be done? Infrared repairs can be performed in a wider range of conditions than traditional methods, but wind and cold temperatures increase heating times significantly. In western Canada, the optimal season is April through November.

How long does an infrared repair take? A single infrared patch takes 20 to 30 minutes from setup to completion, with 7 to 10 minutes of heating time depending on conditions. A crew can complete 10 to 20 patches in a full day.

Does infrared repair work on concrete? No. Infrared asphalt repair only works on asphalt surfaces. Concrete parking lots and sidewalks require different repair methods.

Asphalt Patching vs Repaving: When Should You Patch Your Parking Lot?

Patching is the right choice when your parking lot has isolated damage like potholes, cracks, or utility cuts, but the overall surface and base layer are still in good condition. If more than 25% to 30% of the surface is deteriorated, or the base has failed in multiple areas, repaving or full replacement is more cost-effective than patching repeatedly.

How do you know if your lot needs patching or repaving?

The simplest way to decide is to walk the lot and assess how widespread the damage is. If you can count the problem areas on two hands, you are looking at a patching job. If you are looking at cracking, settling, and potholes across the majority of the surface, the lot needs resurfacing or replacement.

Specific signs that patching will work include isolated potholes that have not spread to adjacent areas, single cracks or small crack clusters that have not connected into a network, utility cuts or trenches where underground work disturbed the surface, low spots where water pools but the surrounding pavement is solid, and small sections of surface wear near dumpster pads, loading zones, or high-traffic turns.

Signs that the lot has gone beyond patching include alligator cracking (a network of interconnected cracks resembling scales) covering large sections, multiple areas where the surface has sunk or heaved indicating base failure, standing water across broad areas due to grade and drainage problems, and patches from previous repairs that have already failed.

What are the different types of asphalt patching?

Not all patches are the same, and the right method depends on the type and severity of the damage.

Cold patching is the fastest and cheapest option. A crew fills the hole with pre-mixed cold asphalt and compacts it. Cold patches are temporary fixes that work well for emergency pothole repairs in winter when hot-mix plants are closed, but they rarely last more than 6 to 12 months in a commercial lot because the material does not bond well with the existing surface.

Hot-mix patching (cut-and-replace) is the standard permanent repair. The crew sawcuts around the damaged area, removes the deteriorated asphalt and base material, compacts the subgrade, adds new granular base if needed, and lays fresh hot-mix asphalt. This method produces a solid, long-lasting repair that can last 5 to 10 years, but it generates waste material, requires a larger crew, and takes several hours per patch.

Infrared patching uses infrared heaters to soften the existing asphalt, which is then raked, blended with new material and a rejuvenating agent, and compacted back into place. The process creates a seamless thermal bond with the surrounding pavement, eliminating the cold joint that causes traditional patches to fail. Infrared patches typically last 3 to 5 years and cost 30% to 50% less than cut-and-replace because the existing asphalt is recycled in place.

Full-depth patching is used when the base layer has failed. The crew removes everything down to the subgrade, rebuilds the base with compacted gravel, and lays new asphalt. This is the most expensive patching method but the only one that addresses structural failure.

How much does patching cost compared to repaving?

The cost difference between patching and repaving is significant enough that it drives most maintenance decisions for commercial property managers.

Patching individual areas costs $200 to $1,500 per patch depending on size, depth, and method. A day of infrared patching covering 10 to 20 repairs runs $2,500 to $5,000. Cut-and-replace patches cost roughly double that for the same number of repairs. For a 100-space parking lot with 5 to 10 problem areas, total patching costs typically run $2,000 to $8,000.

Resurfacing (asphalt overlay) costs $3 to $7 per square foot. For a 100-space lot of roughly 30,000 square feet, that is $90,000 to $210,000. Resurfacing adds a new 2-inch layer of asphalt over the existing surface, extending the lot's life by 8 to 15 years.

Full replacement costs $5 to $12 per square foot including demolition, base reconstruction, and new asphalt. The same 100-space lot runs $150,000 to $360,000.

The math is clear: patching at $5,000 to $8,000 per year is dramatically cheaper than a $100,000+ repaving project. But patching only works when the underlying structure is sound. Once the base starts failing in multiple areas, annual patching becomes a losing proposition because the repairs themselves start failing within months.

When does patching stop making sense?

There is a tipping point where continued patching costs more over time than repaving would have. The general rule in the paving industry is that when 25% to 30% of your lot surface needs repair, it is time to resurface or replace rather than continue patching.

Other signals that patching has reached its limit include patches from previous years that are already cracking or sinking, new damage appearing faster than you can repair it, drainage problems that cause water to undermine repairs from below, and the lot surface is so uneven from multiple patches that it creates trip hazards and drainage issues.

Age is also a factor. A well-maintained asphalt parking lot lasts 15 to 25 years. If your lot is past 20 years and requiring frequent repairs, the remaining asphalt is too oxidized and brittle to hold patches effectively. At that point, every dollar spent on patching is money that could go toward a new surface.

What is the best patching strategy for a commercial lot?

The most cost-effective approach for commercial property managers is a proactive maintenance program that combines regular inspection with targeted patching before small problems become big ones.

Spring inspection after winter is the most important check of the year. Freeze-thaw cycles, snow plows, and salt applications take a heavy toll on asphalt in western Canada, and damage that was minor in the fall can become a pothole by spring. Walk the lot in April or May and mark every area that needs attention.

Prioritize repairs by severity. Potholes and base failures get fixed first because they grow rapidly and create liability. Surface cracks get sealed to prevent water infiltration. Cosmetic wear gets addressed during scheduled maintenance windows.

Batch your repairs. Calling a contractor for a single pothole is expensive because of mobilization costs. Accumulating a list of 5 to 15 repairs and scheduling them as a single visit gets you better pricing and less disruption. Infrared patching is particularly efficient for batched repairs because the crew can move quickly from patch to patch without the setup time that cut-and-replace requires.

Combine patching with sealcoating. After repairs are complete, sealcoating the entire lot protects both the patched areas and the existing surface from water and UV damage. The sealcoat also gives the lot a uniform appearance, hiding the visual contrast between old asphalt and new patches.

How long do different types of patches last?

Patch longevity varies dramatically by method and conditions. Cold patches last 6 to 12 months in commercial lots and should be considered temporary. Hot-mix cut-and-replace patches last 5 to 10 years when the base is solid and the work is done properly. Infrared patches last 3 to 5 years with proper compaction and base integrity. Full-depth patches with base reconstruction last 10 to 15 years, essentially as long as a new section of pavement.

These numbers assume the underlying cause of the damage has been addressed. A patch over a failed base will fail again regardless of method. A patch over a drainage problem will fail again because water will continue to undermine it. The repair method fixes the symptom, but the root cause must also be addressed for the repair to last.

The bottom line

Patching is the right call for parking lots in generally good condition with isolated problem areas. It costs a fraction of repaving and extends the useful life of your lot by years when done proactively. The key decisions are choosing the right patching method for the type of damage, batching repairs for cost efficiency, and knowing when the lot has crossed the threshold where continued patching is throwing money at a surface that needs replacement. For most commercial properties, a spring inspection followed by a batched repair visit is the most practical and cost-effective maintenance approach.

How Much Does Parking Lot Striping Cost in Canada?

How Much Does Parking Lot Striping Cost in Canada?

Parking lot striping in Canada costs between $0.25 and $1.00 per linear foot, with most commercial projects ranging from $2,000 to $8,000 depending on lot size, paint type, and whether the lot is being striped for the first time or restriped over existing lines.

What does parking lot striping cost per linear foot?

Parking lot line painting in Canada typically costs $0.25 to $1.00 per linear foot, depending on the type of paint used and the complexity of the project. For a standard commercial parking lot with 25 to 50 spaces, expect to pay $400 to $800 for restriping over existing lines. New striping on unmarked asphalt costs 50% to 70% more because the contractor needs to measure and lay out the entire lot from scratch.

These costs vary by province. Alberta and British Columbia tend to run higher due to labour rates and shorter painting seasons. Most contractors require a minimum project size of $500 to $1,000 to cover mobilization costs, so smaller lots may pay a premium per foot.

What factors affect parking lot striping cost?

Several factors determine the final price of a parking lot striping project. The size of the lot is the biggest driver, as larger lots require more paint, more labour, and more layout time. A 50-space lot might take a crew half a day, while a 200-space lot could take two full days.

Paint type also matters. Water-based latex paint is the cheapest option at $0.25 to $0.50 per linear foot, but it wears faster in high-traffic areas. Solvent-based alkyd paint costs more but offers better fade resistance. According to Alberta Transportation's Highway Pavement Marking Guide, alkyd paints are the most common type used across the province, though they release volatile organic compounds during application. Water-based latex paints contain significantly less lead-based compounds and have comparable durability.

Other cost factors include the condition of the asphalt surface (cracks and potholes increase prep time), accessibility of the lot (tight spaces or multi-level parkades cost more), weather conditions during application (paint needs dry conditions and temperatures above 10C), and whether the lot needs to remain partially open during work.

How much do additional markings cost?

Beyond standard line striping, most parking lots need additional markings that add to the total project cost. Accessible parking symbols cost $15 to $30 each, and Canadian accessibility standards under CSA B651:23 require specific dimensions and placement for accessible spaces. Fire lane markings cost $25 to $75 per section. Directional arrows cost $10 to $100 each depending on size. Crosswalks and pedestrian zones cost $50 to $200 per crossing. Speed bump painting costs $20 to $50 per bump. Custom stencils for logos, reserved spots, or numbered spaces cost $20 to $200 each. Curb painting runs $1 to $4 per linear foot.

For a typical 100-space commercial lot with accessible spaces, fire lanes, directional arrows, and crosswalks, the additional markings can add $500 to $2,000 on top of the base striping cost.

What is the difference between paint types for parking lots?

The choice of paint directly affects how long the striping lasts and how much you spend over time. Alberta Transportation's Approved Products List (updated May 2026) categorizes marking materials into paint systems and durable products.

Water-based latex paint is the most affordable option. It dries quickly (30 seconds to 2 minutes), has low VOC emissions, and works well for low to moderate traffic lots. Expect to repaint every 1 to 2 years in high-traffic areas.

Alkyd (oil-based) paint costs slightly more and takes longer to dry, but offers better adhesion on older asphalt surfaces. Alberta Transportation notes that alkyd paints are suitable for all types of pavement marking applications but are the least durable option and release VOCs during application.

Thermoplastic and durable markings are the premium option, lasting 3 to 5 years or more. They cost significantly more upfront but reduce long-term maintenance costs for high-traffic lots like shopping centres, hospitals, and transit hubs. Alberta Transportation maintains a list of approved proprietary durable marking products that meet provincial standards.

How often does a parking lot need restriping?

Most parking lots need restriping every 1 to 2 years, though the exact frequency depends on traffic volume, weather exposure, and the type of paint used. Alberta Transportation's Pavement Marking Guide states that re-marking programs should be based on the degree of wear to which markings are subjected, rather than a fixed time period.

High-traffic commercial lots like grocery stores and shopping centres may need annual restriping, especially in Alberta where winter conditions, snow removal equipment, and road salt accelerate paint wear. Lower-traffic lots like office buildings or medical clinics can often go 18 to 24 months between applications.

The City of Edmonton's Manual for Pavement Marking Design (2022) references the Transportation Association of Canada (TAC) standards and the Manual of Uniform Traffic Control Devices for Canada as the baseline for marking quality. Both emphasize that markings must remain legible and retroreflective for nighttime visibility, which is the practical trigger for restriping.

Is it cheaper to restripe or repave a parking lot?

Restriping is dramatically cheaper than repaving. A full restriping of a 100-space lot costs $2,000 to $5,000, while repaving the same lot runs $50,000 to $150,000 or more. Restriping refreshes the appearance and safety of the lot at a fraction of the cost.

However, if the asphalt surface is severely cracked, potholed, or has drainage issues, striping over damaged pavement is a waste of money. The new lines will crack and peel along with the surface. In that case, patching or sealcoating the damaged areas before striping is the better approach.

A proactive maintenance schedule that includes regular sealcoating every 2 to 3 years and restriping every 1 to 2 years can extend the life of a parking lot by 10 to 15 years compared to a lot that receives no maintenance.

The bottom line

For most commercial properties in western Canada, parking lot striping costs $2,000 to $8,000 per project, with ongoing restriping every 1 to 2 years. The biggest cost decision is paint type: water-based latex is cheapest upfront but needs more frequent reapplication, while thermoplastic costs more initially but lasts 3 to 5 years. Getting quotes from multiple contractors and specifying the paint type in the contract ensures you know exactly what you are paying for and how long it will last.

Frequently Asked Questions

How much does it cost to stripe a parking lot in Canada? Parking lot striping costs $0.25 to $1.00 per linear foot in Canada, with total project costs ranging from $2,000 to $8,000 for a standard commercial lot. New lots cost 50-70% more than restriping existing lines.

How long does parking lot paint last? Water-based latex paint lasts 1 to 2 years in high-traffic areas. Alkyd paint has comparable durability. Thermoplastic markings last 3 to 5 years or more, making them the most cost-effective option for busy lots.

What time of year is best for parking lot striping? Late spring through early fall is ideal, as paint needs dry conditions and temperatures above 10C to cure properly. In Alberta and western Canada, the optimal window is May through September.

Do I need accessible parking spaces in my lot? Yes. Canadian accessibility standards under CSA B651:23 require accessible parking spaces in commercial lots. The number and dimensions of accessible spaces are regulated by provincial building codes and municipal bylaws.

How long does parking lot striping take? A standard 50 to 100 space lot takes 1 to 2 days to complete, including layout, painting, and drying time. The lot typically needs to stay closed or partially blocked for 30 minutes to 2 hours after painting for the lines to dry.

Can you stripe a parking lot in the rain? No. Paint needs dry pavement and dry conditions to adhere properly. Most contractors will reschedule if rain is expected within 4 hours of application. Applying paint to wet surfaces results in poor adhesion and premature peeling.

What is the standard width for parking lot lines? Standard parking lot lines are 100mm (4 inches) wide, consistent with Alberta Transportation's pavement marking standards. Accessible space lines and fire lane markings may be wider for visibility.

Sources

How Often Should Parking Lots Be Restriped?

Most commercial parking lots should be restriped every 12 to 24 months, depending on traffic volume, weather exposure, and the type of paint used. High-traffic lots like shopping centres and grocery stores often need annual restriping, while lower-traffic office or medical lots can go up to two years between applications.

Why do parking lot lines fade?

Parking lot lines fade because of a combination of traffic wear, UV exposure, and weather. Every vehicle that drives over a painted line removes a microscopic layer of paint. In western Canada, the problem is compounded by snow removal equipment, salt and sand applications, and freeze-thaw cycles that crack and lift paint from the surface.

The type of asphalt also matters. Older, rougher surfaces absorb more paint during application, which means less paint sits on the surface where it is visible. Smoother, newer asphalt holds paint better and lines last longer.

Faded or missing lines create real problems. Drivers lose visual guidance, parking becomes chaotic, and property owners face increased liability if an accident occurs in a poorly marked lot.

How do you know when it is time to restripe?

The simplest test is visibility. If you can stand at one end of your lot and struggle to see the lines at the other end, especially at dusk or in wet conditions, it is time to restripe. Specific signs that your lot needs attention include lines that are more grey than white or yellow, gaps where paint has worn away completely at turn points and high-traffic lanes, accessible parking symbols that are faded or incomplete, fire lane markings that are no longer clearly visible, and directional arrows that drivers are ignoring because they cannot see them.

For property managers who oversee multiple lots, a simple annual walkthrough in spring after snow season is enough to assess which lots need restriping that year.

What affects how long parking lot lines last?

Traffic volume is the biggest factor. A grocery store lot with hundreds of vehicles per day will wear through paint much faster than a medical office with 30 cars. Drive aisles and entry lanes wear fastest because every vehicle passes over the same lines.

Paint type determines the baseline durability. Water-based latex is the most affordable option but wears fastest, typically lasting 12 to 18 months in moderate traffic. Alkyd (oil-based) paint offers similar durability with better adhesion on older surfaces. Thermoplastic markings are the premium option, lasting 3 to 5 years even in high-traffic areas, but they cost significantly more upfront.

Climate plays a major role in western Canada. The painting season runs from May through September when temperatures are consistently above 10C and rain is less likely. Lines painted late in the season get less curing time before winter, which can shorten their lifespan. Snow plows, graders, and ice scrapers are hard on painted surfaces, and lots that are plowed frequently lose their markings faster.

Surface condition also matters. Paint applied to cracked, potholed, or oil-stained asphalt does not adhere well and peels prematurely. Addressing surface repairs before striping extends the life of the new markings.

What is the best time of year to restripe a parking lot?

Late spring is ideal. The asphalt has dried out from winter moisture, temperatures are warm enough for proper paint curing, and you get the full summer and fall of use before winter weather starts wearing the lines down again. In Alberta and BC, the optimal window is May through September.

Avoid striping too early in spring when overnight temperatures still drop below freezing, or too late in fall when rain and cold can prevent proper curing. Paint needs at least 30 minutes of dry conditions above 10C to set, and ideally several hours without rain.

If your lot absolutely needs restriping outside the optimal season, some contractors offer cold-weather formulations, but these cost more and may not last as long as paint applied in warm conditions.

Can you restripe over existing lines?

Yes, and this is standard practice. Restriping over existing lines is faster and cheaper than removing the old lines and starting fresh. The contractor cleans the surface, may do light prep work, and applies new paint directly over the faded markings.

The exception is when you are changing the layout of the lot. If you need to move lines, add spaces, change traffic flow, or reconfigure accessible parking, the old lines need to be removed first. Line removal is done by grinding, blasting, or chemical stripping, and it adds cost to the project.

If you are restriping without changing the layout, the existing lines serve as a guide for the new application, which speeds up the work and reduces layout costs.

How to extend the life of your parking lot lines

Regular sealcoating every 2 to 3 years protects the asphalt surface and creates a smoother base for paint to adhere to. Fix cracks and potholes before restriping so the new paint has a solid surface to bond with. Use higher-quality paint or thermoplastic for high-traffic areas like drive aisles and entry lanes, even if you use standard paint for individual parking stalls. Adjust snow removal practices to minimize blade contact with painted surfaces where possible.

A proactive maintenance schedule that combines sealcoating, crack repair, and regular restriping can extend the useful life of a parking lot by 10 to 15 years compared to a lot that receives no preventive maintenance.

What about accessibility markings?

Accessible parking space markings have specific requirements under Canadian standards. These markings need to be clearly visible and properly dimensioned, including the international symbol of access, access aisle markings, and signage. Faded accessible markings are not just an aesthetic issue, they can result in bylaw violations and fines.

When scheduling a restriping project, always include accessible markings in the scope of work. These are typically the first markings to be noticed by inspectors and the most important for compliance.
