MastaSmooth Cornice Cement Knauf

MastaSmooth is a super fine, white plaster based cornice cement. It is used to attach cornice and decorative features to walls and ceilings. It has a consistent working time of 30 minutes with a 45 minute setting time, and with its high strength and ultra-white finish is perfect for fixing ornamental cornice. Due to its ultra-white finish it is ideal for installing cornice to OPAL board.

A smooth gauge is achieved by extended mixing using an electric mixer on a low speed with the resulting consistency thinner than normal. MastaSmooth has good body and excellent initial grab. It is great to straight stop and clean to leave a smooth, white finish. MastaSmooth provides an even and gradual 45 minute set even with extra mixing.
