Penta N.C. Sanding Sealer – Clear Quart – Fast-Drying Foundation for a Flawless Wood Finish

Penta N.C. Sanding Sealer is a premium, clear Nitrocellulose (N.C.) based coating specifically engineered to prepare interior wooden surfaces before the application of final topcoats like lacquer or varnish. The formula is designed for fast drying, allowing for quick project turnaround. Its primary function is to deeply penetrate the wood fibers, effectively filling wood pores and slightly raising the grain. This action provides a high-solids film that is easy to rub down, ensuring a perfectly smooth, level, and sealed foundation. By using this sanding sealer, you minimize the amount of final topcoat absorbed by the wood and guarantee the topcoat adheres uniformly, resulting in a deeper, richer, and more professional final finish.

Key Benefits

• Fast-Drying NC Formula: Allows for rapid sanding and recoating, significantly speeding up the finishing process.
• Excellent Pore Filling: High solids content quickly fills open wood pores, eliminating imperfections.
• Smooth Base Coat: Easy to sand to a fine powder, creating an ultra-smooth, level surface for the topcoat.
• Seals Wood: Prevents excessive absorption of the final lacquer or varnish, maximizing its aesthetic value.
• Clear Finish: Maintains the natural appearance of the wood grain before the final protective layer is applied.

Application Instructions

• Preparation: Ensure the wood is fully sanded (typically 180-220 grit), clean, dry, and free of dust, grease, and moisture.
• Application: Apply 1 to 2 coats evenly by brush, cloth, or spray.
• Thinning: Thin with N.C. Thinner if necessary for spray application or better penetration.
• Sanding: Allow the coat to dry fully (typically 30-60 minutes). Sand lightly with fine sandpaper (e.g., 220-320 grit) to achieve a smooth, powdery surface.
• Topcoat: Remove all sanding dust completely and apply the final lacquer, varnish, or polish.

Pro Tips

• ALWAYS use N.C. thinner (Lacquer Thinner) for thinning and clean-up, as this is a nitrocellulose-based product.
• Work in a well-ventilated area due to the strong solvents in the N.C. formula.
• The purpose of sanding sealer is to be sanded off; only leave enough to fill the pores and seal the wood.
• For very porous woods, apply a thin first coat, sand lightly, and then apply a slightly thicker second coat to ensure all pores are filled.
• Wipe down with a tack cloth or compressed air after final sanding to ensure zero dust remains before the topcoat.
