Rust-oleum 224740 Varathane Sanding Sealer 1 Gallon

Product Description

The RUST-OLEUM 224740 is a gallon-size sanding sealer designed to prepare bare wood surfaces before a topcoat finish. It seals wood grain, raises the fiber structure slightly, and cures to a film that sands easily — reducing the effort required to achieve a smooth surface before applying the final coat. Low odor formula makes it suitable for use in occupied or enclosed spaces. Cleanup requires only soap and water, making it a practical choice for professional finishing work and production cabinetry shops alike.

This sanding sealer is appropriate for residential and light commercial woodworking applications, including furniture, cabinetry, millwork, and interior trim. It is formulated to work as a base coat under oil-based polyurethane, water-based polyurethane, lacquer, or shellac topcoats. Finish carpenters, cabinetmakers, and woodworking professionals typically apply this product by brush, roller, or spray equipment before final sanding and topcoat application.

Compatibility

Installation Notes

Application should be performed by finish carpenters or woodworking professionals following standard surface preparation practices. Ensure the wood surface is clean, dry, and free of dust, wax, and contaminants before applying. Allow each coat to dry fully before sanding with fine-grit sandpaper, then remove all sanding dust before applying the topcoat. Work in a well-ventilated area even with low-odor formulas, and follow local VOC regulations where applicable.
