MDF Primer Johnstone’s Trade MDF Primer is a high-performance, water-borne, combined primer and undercoat, specifically formulated for use on medium density fibre boards. It provides a low-odour, quick-drying alternative to conventional solvent-borne primers, and produces an ideal surface for over-coating with subsequent topcoat. Recommended for use as a primer for MDF, especially routed, to seal prior to application of a topcoat. It can also be used on chipboard, block-board, planed timber and other wood composites. Johnstone’s Trade MDF Primer has high build and excellent adhesion, and will cover approximately 12-14 square metres per litre, depending on the nature and porosity of the surface being painted.
