Everkem SilTex 40 Siliconized Acrylic Latex Caulk

The Everkem Diversified Products SilTex 40 is a siliconized acrylic latex caulk designed for long-term building envelope sealing. This 10.1-ounce cartridge delivers 40+ year durability with strong, flexible adhesion that works on both interior and exterior applications. The formula meets ASTM-C834 standards for building envelope performance and carries ASTM-G21 certification for mold and mildew resistance.

The caulk features low VOC content at just 16 g/L, making it compliant with LEED v4 emissions requirements and suitable for green building projects. You can paint over it once cured, and the mold-resistant formula holds up in high-moisture environments. The siliconized latex blend provides better flexibility than standard acrylic caulks while maintaining paintability that pure silicone lacks.

This is the go-to caulk for window and door perimeter sealing, trim work, and general construction gaps where you need both weather resistance and the ability to paint. Works well for contractors who need one product that handles both rough framing gaps and finish work where appearance matters.
