Yost's Geocel 2300 tripolymer sealant is designed to combine the flexibility of urethanes, the paintability of acrylics and the long life expectancy of silicones. It can be applied year round (see below). It does not attract dust and dirt like silicone caulk and is is compatible with asphalt roofs. These 10.3 oz cartridges are used with a caulking gun.
Temperature Recommendation: The 2300 Geocel caulk is easier to apply in warmer to mildly cold climates. At 40 degrees and below, its best to take it from a warm area and caulk outside while the tube is still warm.
