Versatile CaberMDF explained

Here West Fraser answers your questions on the popular MDF range.

There are several grades of CaberMDF, can you give me an overview of which type should be used and where?

Our CaberMDF Trade is suitable for general purpose where simple profiles are needed, as is our Trade MR; while the MR can be used in humid conditions.  The Pro is for architectural mouldings like skirtings and architraves, while the Pro MR can be used for most things in damp conditions.  Our CaberMDF Industrial is the most versatile type as it can do everything, including facilitating deep routed profiles for membrane-pressed PVC doors, as well as designs which require advanced routed profiles and painted finishes.

That leads to my next question, what sort of paint can I use on MDF?

Oil-based paint is best as the material is less absorbent and customers like the quality of finish which can be achieved on the very smooth surfaces that machining leaves.

How do I secure the MDF panels once they’re ready for installation?

When it comes to fixing, most types of screws can be used, although the best results are obtained with parallel thread screws.

What thicknesses does CaberMDF come in, and is it fire-resistant?

Our CaberMDF is supplied as 6mm thick panels – and no, they are not fire-resistant.

I noticed that some of the panels are different colours – why?

To differentiate between the grades – CaberMDF is available in five main grades: Trade (Light), Pro (Standard), Trade Moisture Resistant, Pro Moisture Resistant and Industrial. Colour is a means of identification between the MR and non-MR grades and does not correlate to the boards’ performance.

Trade, Pro and Industrial grades are the traditional ‘sandy’ colour, whereas Pro Moisture Resistant and Trade Moisture Resistant are distinguished by a green hue.

I’ve heard that MDF is harmful to health – is this true?

Absolutely not – another one of those urban myths. All wood-related products create dust when cut or machined. We advise the use of appropriate PPE and ventilation when sawing, machining or drilling any timber boards including MDF. 

Okay then, if MDF isn’t harmful to actually work with, is it low in formaldehyde emissions, which can affect occupants’ health?

Yes – CaberMDF meets all the requirements of latest E1 definition for the chemical when tested according to EN120.
