BRIWAX SHELLAC SANDING SEALER 250ml

Shellac Sanding Sealer is a traditional shellac-based sealer that helps tighten up grain before sanding or applying oils or waxes. It stops oils, waxes, and polishes from penetrating deep into open-grained wood. It also prevents the acids in some woods (like Matai and Totara, or customwood) reacting with the subsequent finishes.
