Description
Coovar Shellac Primer is a premium, fast-drying shellac-based primer designed to provide exceptional stain blocking, adhesion, and sealing performance across a wide range of interior surfaces. Formulated for professional decorators and demanding refurbishment projects, it is particularly effective where persistent stains, odours, or difficult substrates must be sealed prior to topcoating.
