FS Mastic Soft is a two-component, UV-stable polyester filler and adhesive for bonding and filling natural and engineered stone. It is made of unsaturated polyester resin in styrene with mineral fillers, and its soft consistency makes it well suited to vertical surfaces. It gives a seamless, defect-resistant finish that can be machined, sanded, and polished to a smooth sheen, and it is available in matching shades so filled joints blend with the stone.
Suitable for natural and engineered stone.
Mix the two components before use. Clean tools of residual resin with Epoxy Remover.
