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.

Product Advantages

• Optimised bulk density
  
• Easy to shape, tools last longer
  
• Homogeneous horizontal structure
  
• A complete, affordable substitute for solid wood for making strips and mouldings
  

Applications

• Special MDF for shaped strips, mouldings and panels and for making milled, laminated panels for interior uses
• Furniture

Easy-to-Use Lightweights

SWISS KRONO MDF – panelling grade boards are easy to work and use. Their homogeneous structure ensures precise milling results. They are easy to veneer, laminate or thermofoil.

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.

Screws

• 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.

Gluing

• 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.
