Can you just use sealer on the asphalt cracks?

For small cracks smaller than 25 mm, sealer can be used. For larger cracks, even a slurry seal will not fill cracks in the pavement. The aggregate in a slurry seal is meant for minor imperfections, not cracks. Cracks come in many sizes, and we repair cracks smaller than 2.5 cm wide, but ideally less than 2 cm. Larger cracks need a different application. Crack filler helps to slow the progress of pavement damage. Once it has started, the damage tends to progress at an increasing rate. The sooner cracks are filled, the longer you can delay the damage.

Do you need to clean the lot before sealing it?

Yes, the lot needs to be clear of litter, debris and sand before starting to do crack filling or seal coating to ensure proper adhesion.

Do you need to seal coat after crack filling?

No, you can only have crack filling done. However, if you have significant cracking slurry seal coating may help to prevent more cracking.

Do you seal coat driveways?

Not at this time, our focus is on parking lots.

How long after seal coating can you paint new lines?

Ideally, you should wait as long as possible to make sure there are no chemical interactions between the seal coat and the line paint. We recommend at least 12 hours between applications, but 24 hours or longer is better.

How long does it take for seal coating to cure?

After the seal coat has been applied, it must be allowed to fully cure before traffic is allowed on again. During the cure time, the sealer is still bonding to the existing asphalt, and vehicles can break those weak bonds. Curing may take between a few hours and a few days, depending on conditions such as temperature and humidity. For optimal curing rates, we recommend seal coating asphalt from July to September in Winnipeg.

What is crack fill?

Our hot-pour crack filler is a flexible, rubber-like commercial-grade product that is used to repair cracks in asphalt pavements. It starts out as a solid, rubber brick which we melt down in a special kettle and applicator that is heated to 400 Fahrenheit. Once applied in the cracks, it hardens up deep inside and helps to keep water from penetrating the asphalt and causing further damage. The fill remains semi-flexible and expands and contracts with the asphalt.

It is not a permanent solution, but just a way to buy extra time for your asphalt.

What is the difference between Asphalt Sealing and Sand Slurry Seal Coating?

Asphalt Sealing is typically the more widely offered asphalt-protection method for residential properties in Winnipeg and Manitoba. This is because it generally has a lower cost per square foot. The finished appearance has a significantly glossier look and is very slippery when wet, unlike the sand slurry seal coat which is flat black and textured for a non-slip finish. Unfortunately, even the highest quality oil-based asphalt sealer doesn’t last more than six months to one year and needs to be freshened up more annually.

Unlike Asphalt Sealing, Sand Slurry Seal Coating has a non-slip, jet black texture once it’s completely cured. Despite the fact that the upfront costs for sand slurry seal coating are higher than for asphalt sealing, the cost per year of service is much lower and will save the property owner significant maintenance costs over the long run. A well-done and properly maintained professional sand slurry seal coat application should last you for about four to six years without requiring additional applications or expensive repairs. Sand slurry seal coat has up to 2.5 pounds of silica sand blended into the water-based emulsion to give it its signature non-slip and jet black texture.

Once applied, both asphalt sealing and sand slurry seal coating need about 24 hours to cure.

Seal coating is not meant to rejuvenate deteriorating parking lots, it is meant to extend the life of your lot. Seal coating should be done 2-3 years after it is first laid down and then every 4-6 years after that.

If your parking lot is in great disrepair with a lot of giant potholes and cracks all over, then it might be a good idea to invest in a new parking lot or asphalt overlay.

Will you be able to see the repaired cracks after seal coating?

Yes, the seal coat will add a layer to the existing surface but you will still see both the previous lines and any crack repairs. Both line paint and crack fill is smoother than bare asphalt.
