SUBSTRATE PREPARATION

All surfaces must be clean, dry, free from dust, grease and other contamination.

Apply using a thin pointing trowel or putty knife, working well into the joint and ensuring no voids remain. Finish smooth to a triangular fillet. When used for fillet pointing between frame and surround, joints should be a minimum width of 10 mm with a minimum depth of 6 mm.


OVERPAINTING AND MAINTENANCE
