Decorative Caulk Mastic 380ml – White

Smooth Finish. Paintable. Professional Result.

Decorative Caulk Mastic is a flexible, water-based mastic designed for filling and sealing internal decorative joints — the finishing touch that separates a professional installation from an amateur one. It applies cleanly, tools to a smooth finish, and can be overpainted once dry, making it ideal for use between skirting boards, architraves, coving, and walls before the final coat of paint goes on.

Supplied in a 380ml cartridge in White.
