NC Sanding Sealer is a type of Nitrocellulose (NC)-based paint commonly used as an undercoat in wood finishing processes. It serves to seal the pores of wood, providing a smooth and uniform surface that enhances the application of subsequent layers of paint or polish.

• Composition: Made of nitrocellulose resin, plasticizers, and solvents, often combined with other additives to improve adhesion and sandability.
• Purpose: Acts as a filler and sealer to prepare wood surfaces for finishing.
• Appearance: Usually dries to a clear or semi-transparent film, retaining the natural appearance of the wood grain.
