The Trade Coatings Internal MDF Wood Sealer is designed for professional joiners, furniture makers, and DIY enthusiasts who require a reliable base coat to ensure a flawless topcoat finish on Medium Density Fiberboard. Its primary benefit is providing a smooth, non-swelling surface that protects the integrity of the board during the painting process, though users must note that it requires proper sanding preparation to achieve optimal results.

No, this product is formulated specifically for interior MDF joinery and furniture projects.
It provides an excellent base, but you must sand it properly to ensure the texture is leveled before topcoating.
Usually, one to two coats are sufficient, depending on the porosity of the MDF edges.
It is designed to be compatible with most standard interior topcoats, but always test on a scrap piece if using specialized finishes.
You can expect approximately 12m² per litre, though this may vary based on the absorption rate of the MDF.
This is normal for MDF as moisture raises the wood fibers; simply sand the surface lightly with fine-grit sandpaper until smooth.
Ensure the sealer was fully cured and that the surface was wiped free of sanding dust before applying the final topcoat.
Before application, ensure the MDF surface is clean, dry, and free of dust. Sand the raw MDF lightly to remove any fuzz or loose particles. Apply the sealer using a high-quality synthetic brush, a short-nap roller, or a spray gun. Once the initial coat is dry, inspect the surface for any raised fibers and perform a light sand before applying your chosen topcoat. Store the container in a cool, dry place, ensuring the lid is sealed tightly to prevent skinning. Clean your brushes or spray equipment promptly after use with the appropriate solvent as recommended for single-pack systems.
