Silicone Joint Sealant

Dow Corning Self-Leveling Silicone Joint Sealant is designed to perform as a durable long-term joint seal for asphalt and/or concrete pavements. It firmly adheres to asphalt and concrete pavements.

Dow Corning Silicone has good weather-ability – its 100 percent silicone rubber is virtually unaffected by sunlight, rain, snow,ozone or temperature extremes. Most organic sealants stiffen in cold temperatures and soften in warm weather. Organics can degrade and crack in sunlight.

Fully elastic – the sealant can be stretched to 100 percent or compressed to 50 percent of the joint width and held there. When released, it will recover 95 percent or greater of the original dimension. The extension and/ or compression can be repeated many times and the sealant will resume its original shape without splits or cracks.

Resilient – once cured, the sealant prevents stones and other non-compressibles from entering the joint by “squeezing” them out as soon as the force pushing the non-compressibles into the sealant is removed. It lasts 3 times longer than any other concrete joint sealant. Applicable standards meet Department of Transportation (DOT) specifications that require a low-modulus, self-leveling sealant with high movement capability

Use of silicone as a joint and crack sealant is HOA approved and recommended
