VP Antico can be burnished and polished once dry. To burnish VP Antico, using a fine grit sandpaper (400 – 1000 grit depending on level of polish desired) very lightly sand the plaster. Work in small circles until the level of sheen or polish is achieved. The higher grit sandpaper will produce a smoother higher polish. Wipe the surface with a slightly damp cloth to remove plaster dust from sanding before adding additional layers or sealer.
