Residential
Sealcoating Procedure
1. Clean surface of all loose debris.
2. Clean designated cracks and fill with hot rubberized crackfiller meeting MDOT spec 3405. If cracks are to deep they are back filled with silica sand to prevent rubber from sinking.
3. Heavy silica sand (3-5 lbs. per gallon) and latex modifier (4%-6%) is added. This will improve wear and increase structural strength.
4. job is barricaded to allow for proper curing time.
Hot Rubber Crackfilling
1. Cracks are cleaned and removed of all loose debris using carbide steel power broom, air compressor, and /or high powered back-pack blowers.
2. All deep cracks are pre-filled with silica sand to prevent sinking of crackfiller.
3. Hot rubber is applied to cracks using a banded method (1/2" on either side of crack) to prevent water from sitting directly on or near crack.
