StyroCaulk is a Heavy Sand based material that seals StyroTrim treatments to any home or structure. StyroCaulk is not to be used as the adhesive for trims.(normal construction adhesive is required) It is a 70% solid mixture of high-performance acrylics and sand specially blended for breathability, adhesion, flexibility, texture and toughness made to fill seams and cracks in stucco walls as you would with regular caulk. It is not affected by water or moisture-penetration and is designed for a long bonding life without cracking and peeling. Coverage: a 3/16 inch bead will cover approximately 50 linear feet.

'StyroCaulk was easy to use and took the texture of the stucco well'
