Zinsser Seal Coat - 1 Litre

Zinsser Seal Coat is the perfect sanding sealer for interior woodwork. It deeply penetrates the surface and dries quickly to give wood surfaces a rich tone. It is recommended to use under strong solvent-based topcoats to protect and ensure superb adhesion. Seal Coat also ensures the adhesion of solvent-based polyurethane, water-based polyurethane, lacquer, and other clear finishes. This product can also be used to create a barrier that seals in odours from certain types of woods and chipboard. As well as giving extra beauty and warmth to water-based polyurethanes.

• Does not darken or yellow
• Compatible with clear wood finishes
• Seals ALL interior wood
• Quick drying

Always ensure the surface to be treated is clean, dry, and free from any dust, grease, oil, wax, mould, or possible contaminants that may interfere with adhesion.
