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.
