GSA Cornice Adhesive 2.5kg

Fixing a length of cornice is a two-part job: getting it to grab, then getting the joins clean. This cornice adhesive does both.

It's a gypsum-based setting compound. Mix it with water to a smooth paste and it grabs the cornice at the wall and ceiling junction with a strong initial hold, then sets hard. The same mix fills and finishes the mitres and joins.

Works on plasterboard and fibre cement. Mix what you'll use, since a setting compound goes off in the bucket rather than drying out slowly.
