Indigo Sleek NC Sanding Sealer

Indigo Sleek NC Sanding Sealer is an essential preparatory coat for achieving a high-quality finish on interior wooden surfaces. Based on a fast-drying nitrocellulose resin, its primary role is not to be the final finish, but to prepare the wood for it. It penetrates the wood to seal its porous surface, which prevents the topcoat from being absorbed unevenly.Furthermore, it contains special sanding agents that make it incredibly easy to sand down to a fine, smooth powder without clogging the sandpaper. This crucial step ensures the final topcoat has a perfectly flat, uniform base to adhere to, resulting in a significantly smoother and more beautiful final appearance.

Key Features

• Nitrocellulose (NC) Formula: Ensures extremely fast drying, allowing for rapid sanding and recoating, which helps in completing projects faster.
• Excellent Filling & Sealing Properties: Effectively seals the pores in wood and MDF, providing a uniform, non-absorbent base for the application of a topcoat.
• Superior Sandability: This is its main feature. The sealer is formulated to be easily sanded to a smooth, powder-like dust, creating a flawless surface without significant effort.
• Prevents Topcoat Absorption: By sealing the surface, it reduces the amount of topcoat material needed, making the overall finishing system more economical.
• Strong Adhesion: Promotes a powerful bond between the wood substrate and the subsequent coats of lacquer or paint, improving the durability of the entire system.
• Clear Film: Dries to a transparent finish that does not hide the natural grain and beauty of the wood.

Primary Benefits

• Achieve a Flawless Finish: Creates the ultra-smooth foundation necessary for a mirror-like or perfectly matt topcoat.
• Saves Time and Labour: Its quick-drying and easy-sanding nature dramatically speeds up the most laborious part of wood finishing—surface preparation.
• Improves Topcoat Performance: Ensures the final finish has better holdout, gloss retention, and overall appearance.
• Cost-Effective: Reduces the consumption of more expensive topcoat paints or lacquers.

Role in a Finishing System

This product is an undercoat and should always be followed by a topcoat. The typical application process is:

1. Prepare the Surface: Ensure the raw wood is clean, dry, and smooth.
2. Apply Sealer: Apply 1-2 coats of Indigo Sleek NC Sanding Sealer.
3. Sand Down: Once thoroughly dry, sand the surface with a fine-grit sandpaper (e.g., 220 or 320 grit) until it is perfectly smooth to the touch.
4. Apply Topcoat: Clean the dust off and apply your desired topcoat, such as Indigo Sleek NC Lacquer, PU, or Melamine.
