Rustins Quick Drying MDF Primer is a water-based primer suitable for new and bare MDF, designed for both indoor and outdoor use. It offers high opacity and can be applied as an undercoat on previously primed or painted surfaces. This primer can be over-coated with water or solvent-based finishing paints. It is available in white or grey. The primer provides exceptional surface sealing for porous MDF, preventing excessive paint absorption and ensuring an even topcoat coverage with fewer coats. Its smooth finish enhances the final appearance of paint jobs by preventing patchiness and uneven absorption. Specifically formulated for interior MDF and bare wood applications, it is ideal for furniture, shelves, crafts, and panelling to achieve a long-lasting finish. The water-based formula offers excellent coverage with minimal odour and can be applied using a brush or roller, making it suitable for both professionals and DIY enthusiasts.
