MDF Sealer for Cabinets, Furniture & Interior Joinery
Trade MDF Sealer is a single pack MDF sealer designed for use before applying coatings, helping create a smoother, more professional finish on prepared board surfaces. It is intended to seal MDF effectively without swelling the board or compromising its integrity, making it a practical base coat for joinery, cabinetry and furniture work.
Suitable for brush, roller or spray application, this fast-drying sealer is easy to use and easy to sand before overcoating. The technical data sheet states that it does not affect the glue that binds the fibres of MDF board and provides an effective seal while maintaining the structure of the panel.
