MDF is a special type of wood-based material made from waste material from the timber industry mixed with adhesive. MDF is dimensionally stable and easy to work with. This type of MDF is mixed with black pigment and is therefore black right through.

Good to know
This type of MDF is mixed with black pigment and is therefore black right through. Untreated, it appears dark grey, but with a little oil it takes on a beautiful black colour. MDF is often used for models and prototypes. Black MDF is not suitable for outdoor use or in damp environments without a finish.
Line and surface engraving
Both line and surface engraving are possible on MDF. The material takes on a slightly darker shade where it is engraved. Surface engraving, however, is only possible in A-sizes.
Avoid burn marks
Protective film on the top and/or bottom can be selected as an option when ordering, which helps to avoid the worst soot and burn marks caused by the laser. However, protective film is not available for flat engraving.
Laser cutting
Top – Along the cut line, the wood will take on a slight dark discolouration.
Edges – The edges will turn dark and may stain other surfaces. Excess soot can be wiped away with a slightly damp cloth, but the edges will remain dark even afterwards. The thicker the MDF, the more soot deposits will form on the edges.
Bottom – Discolouration will occur on the bottom after cutting. This usually takes the form of a hexagonal pattern, depending on the surface on which the cut is made. A film that removes most of this can be selected as an option when ordering. For A-sizes, it is also possible to choose a double-sided adhesive backing, which makes it possible to hang the pieces on, for example, the wall without using nails or screws.
Finishing
Black MDF can be painted, just like standard MDF, but it is usually left untreated, oiled or varnished to protect the surface.
Oiling gives black MDF a beautiful and more intense colour.
