Lightweight – Easy to Shape
Our panelling grade MDF comes in high-quality, lightweight boards with an optimised bulk density for panel applications. It excels with low weight, long tool lives and easy shaping. This wood-based material is ideally suited for creating laminated, milled products for interior uses.
- Optimised bulk density
- Easy to shape, tools last longer
- Homogeneous horizontal structure
- A complete, affordable substitute for solid wood for making strips and mouldings
- Special MDF for shaped strips, mouldings and panels and for making milled, laminated panels for interior uses

General Information on Use of All SWISS KRONO MDF Product
Transport and Handling
- Protect edges to prevent damage.
- These products are for interior use and must therefore be protected from moisture and the weather.
- Do not store outdoors.
- To prevent rising moisture, stack on top of wooden sleepers.
- Acclimate boards before by storing them for about three days beforehand uncovered under the climatic conditions prevailing at the installation site.
- Install only when dry.
Sawing, Milling and Drilling
SWISS KRONO MDF can be sanded, sawn, milled and drilled just like solid wood and using all of the same tools.
- To prevent splitting, it is advisable to predrill holes before using screws. It is standard practice for the holes to be 80% of the screw shaft diameter.
- Do not attach screws to the plate surfaces closer than 20 mm from the edge.
- When attaching screws to the edges, maintain a distance of at least 70 mm from the corners and space them at least 30 mm apart.
- All commercially available wood glues can be used with SWISS KRONO MDF.
- Because the surface layer is denser, it is enough to apply between 80 and 120 g of glue per square meter.
Sanding and Smoothing
- SWISS KRONO MDF comes sanded to a fineness of 150 grit.
- To meet very high quality requirements, eg for coating and painting, the boards should be sanded before and /or after treatment, depending on the application.
Painting, Coating, Waxing and Lamination
- Applying a coating or suitable will minimise the risk that exposure to light will alter the colours, provided that appropriate UV blockers are added.
- Sanded surfaces can be coated just like ordinary wood (with paint, oil, wax etc.).)
- All commercially available paints, coatings and waxes that are suitable for MDF may be used.
- Greatly thinned paint or coating, a low solids content and/or insufficient application can detract from the results.
- Before coating, make sure that the surface is absolutely free of oil, grease, silicone and dust.
- It is strongly advised to carry out a test before proceeding.
- Optimal results are achieved by brushing with strokes at right angles to one another.
