CRL 321 Acrylic Latex with Silicone is a special blend of silicone and acrylic latex that provides superior primerless adhesion to building materials such as wood, brick, glass, plastic, metal and ceramics. CRL 321 is mold and mildew resistant, and is paintable with oil or latex based paint. A truly versatile caulk, CRL 321 also features easy tooling and water clean up. The Silicone gives it flexibility, the Acrylic promotes long life expectancy. Together they form an excellent sealant that can be used around window and door frames; for siding and trim work; caulking tubs and sink tops; thresholds and baseboards. CRL 321 can be tooled for approximately 30 minutes and can be painted over after two hours with oil or latex based paints.
In order to help you better select the correct sealant, we have put together a Silicone and Sealant Selector Chart.
