Smooth Finish. Paintable. Professional Result.

Decorative Caulk Mastic is a flexible, water-based mastic designed for filling and sealing internal decorative joints. It applies cleanly, tools to a smooth finish, and can be overpainted once dry — ideal for use between skirting boards, architraves, coving, and walls before the final coat of paint goes on. The 310ml cartridge is the right size for smaller jobs and touch-up work.

Supplied in a 310ml cartridge in White.
