      For the best results, all finishing materials should obtained. as a complete system from one supplier. Most coatings will built up with a primer followed by basecoat and one or two topcoats. Particular attention should. given to the application of primer to all exposed edges and any face mouldings. as the edges of MDF are more porous than the surfaces. All surfaces and edges should receive the full finishing treatment.

      Several different exterior durability coating systems are available for use on moisture resistant. or exterior grade MDF including masonry and non porous high gloss paints. Microporous paints are not considered to be suitable for finishing moisture resistant. or exterior grade MDF.

      Plaster type finishes can applied to moisture resistant. and exterior grade MDF subject to pre-sealing with an appropriate sealer.

      Companies using moisture resistant. or exterior grade MDF for outside applications in exposed situations. should discuss the suitability of a particular grade of MDF. and the selected finishing system with the materials suppliers. 

water resistant MDF

      Medium density fiberboard, or MDF, is a versatile, inexpensive wood product. that has many applications, including shelving, cabinetry, furniture and moulding. Made from heat-pressed recycled wood fibers and resin. it is available in laminate, veneer and paint finishes, is very strong, easy to work with. and is less likely to tear and chip.

It should noted that whichever method you use, MDF is moisture-resistant. not water-resistant, nor waterproof. and is still prone to swelling and warping if in direct contact with the elements.

      The first and easiest approach is to buy MR MDF. which designed to work well in interior applications where moisture is a concern. Compared to the standard MDF, moisture-resistant MDF is still easy to sand and mill. takes well to most adhesives, veneers and paints. but made with a moisture-repellent resin.

     Step two is to apply the sealant or water-resistant paint, using a 3/8-inch roller. Use a paintbrush to paint the corners and edges. This layer should take about four hours to dry.
