The Best MDF Board: Our Picks
Guide: Questions you should ask yourself before buying an MDF board
What is MDF board and what is it made of?
The fine wood fibre boards are characterised by their smooth yet firm edges. MDF boards are available in thicknesses from 2mm to 60 mm and densities from 600 kg/m³ to 1000 kg/m³. The wood fibre boards are produced by a dry process with the addition of an artificial binder. After production, the boards are differentiated according to their respective raw density range:
- high-density fibreboard (HDF) with a density ≥ 800 kg/m³
- light MDF (L-MDF) with a density ≤ 650 kg/m³
- ultra light MDF (UL-MDF) with a density ≤ 550 kg/m³
The MDF boards can be given additional properties by adding synthetic binders. This can give the boards additional properties such as fire protection, moisture resistance, resistance to biological infestation.
What is the intended use of an MDF board?
The smooth surface of the MDF board, which allows easy processing with paint and varnish, is mainly found in the kitchen. Especially as profile decorations for kitchen furniture. In addition to kitchen furniture, MDF panels are also used as secondary decorations for doors, window frames and prefabricated houses. In powder-coated form, table tops and cover plates have also been made from fibreboard for several years now.
What alternatives are there to MDF boards?
Multiplex board & plywood
Multiplex boards and plywood boards are very similar, both consist of several thin layers of wood that are glued together. The difference between the two boards is the thickness, whereby plywood boards usually only have three to five layers of wood, which are also usually only less than one centimetre thick. Multiplex boards, on the other hand, only start at a thickness of twelve millimetres and consist of at least five layers of wood. Put simply, plywood panels are the light version of multiplex panels.
Experience has shown that birch is used for the individual layers of wood, as birch wood is waterproof. However, layers of birch and poplar are also possible.
The boards are used in the following areas: Vehicle and machine construction, furniture construction, partition walls, stairs and worktops.
OSB boards (coarse chipboard)
Coarse particle boards were originally intended as a waste product of the veneer and plywood industry. However, a use for the coarse boards was found after all. OSB boards consist of coarse chips which are pressed into boards under high pressure and temperature. Due to their characteristic appearance, OSB boards are often used as flooring or decorative elements. However, the most common use of OSB boards is for interior finishing. The strengths of OSB panels include high flexural strength and good water vapour diffusion resistance. In contrast, OSB boards have a high moisture absorption and cannot be painted due to their rough surface.
Chipboard is very versatile in its use due to its fine structure. This is why chipboard is often used in furniture construction as well as in carcassing as a damping material. The production of chipboard is very inexpensive, as it mainly consists of wood residues that are glued and pressed into boards. Chipboard is characterised by its good load-bearing capacity and is available in almost all dimensions.
Similar to OSB boards, chipboard cannot be painted and is highly moisture-absorbent. Nevertheless, they are excellent for not too demanding applications because they offer such good value for money.
The GFM board is a glue-free, building biology alternative to the other boards. The GFM board does not contain any chemical substances, vapours or foils and is still twice as strong as an OSB board. Learn more about the GFM board in the following video.
Cement-bonded wood-based panels
Cement-bonded wood-based panels are, as the name suggests, bonded with cement instead of glue. This gives the boards a smooth cement-grey surface, which is largely resistant to frost, insects and fungus. The cement-bonded slabs are available either in a single layer with a homogeneous structure or in several layers as a composite material. Depending on the density, the cement boards are used for sound and heat insulation or as insulation boards.
Decision: What types of MDF boards are there and which is the right one for you?
We distinguish between the following types of MDF boards:
- MDF board without formaldehyde
- MDF board with primer film
We have listed the advantages and disadvantages of each type below to make your purchase decision easier.
What distinguishes an MDF board without formaldehyde and what are its advantages and disadvantages?
Originally, formaldehyde was only used as a preservative, but now the substance is also used as an adhesive component in woodwork. Formaldehyde is also used in the production of MDF boards. After the wood fibres have dried, they are glued with formaldehyde resins, which are supposed to hold the boards together and make them resistant to moisture. However, the chemical substance is highly harmful to health; formaldehyde has now been classified as a carcinogen.
What are the advantages and disadvantages of an MDF board with primer film?
An MDF board with an additional priming film enables easy lacquering because the priming film is made of high-quality noble cellulose. Priming foils can be applied to particleboard, hardboard or MDF.
Buying criteria: You can use these factors to compare and evaluate MDF boards
We have formulated the following buying criteria for you:
- Intended use
- Additional capability
We will now explain in more detail what is important in the individual criteria.
MDF boards can be purchased already coated, which has the advantage that you do not have to do it yourself and the MDF board has already been professionally coated.
In addition to medium-density fibreboard, there are two other variants of pressed wood panels:
We have already discussed MDF in detail at the beginning of this guide.
Due to its high density of at least 800 kg/m³, HDF board is mostly used in laminate flooring. Due to the high density, HDF boards have an enormous bending strength and a strong tensile strength. Furthermore, HDF boards are sealed on the surface, which facilitates veneering, printing and lacquering.
Ultra Light MDF board has the same capabilities as MDF board, the only difference being that it weighs less and has a lower load capacity.
You don't buy an untreated MDF board without a reason. Depending on the intended use and preferences, the board should be selected. If the board is to be used as floor support, it makes sense to choose an HDF board over an MDF board.
The MDF boards can be given additional properties, e.g. fire protection, moisture resistance, resistance to biological attack, by changing the composition of the synthetic binder or by adding other additives. The price varies depending on the additive.
Facts worth knowing about MDF board
What do I have to pay attention to when laminating my MDF board?
The foiling of MDF boards is basically relatively simple, only the corners and edges can cause problems for some hobbyists. The following video shows you how to master these without any problems.
How do I paint my MDF board correctly?
In the next 5 steps you will learn how to paint the MDF board correctly.
- Preparation: First, the MDF board must be thoroughly cleaned and sanded. It is best to clean the boards with a silicone and grease cleaner. Before priming, wipe the boards again, as the boards must be absolutely clean.
- Priming the MDF boards: Now apply the insulating primer with a foam paint roller. These paint rollers achieve a painted surface that looks as if it has been varnished. This way you will have to sand much less later. After painting the MDF panels, allow the insulating primer to dry completely.
- Sand primed MDF boards: After the boards have dried completely, sand them again. It is best to use fine-grit sandpaper for this. After sanding, the boards should be cleaned again.
- Paint the MDF boards: Now you can paint the MDF boards. Either with a spray gun or alternatively you can use a foam roller.
- Lacquer the MDF boards with transparent top coat: Now that the lacquer has dried, you can apply another coat of clear lacquer. You can also apply this with a spray gun or foam roller.
How can I screw my MDF board correctly?
If you want to screw your MDF board together, there are a few things you should bear in mind. MDF boards can be screwed together just like any other wooden object.
You should be aware that MDF boards are sensitive, which is why a screw should never be screwed in directly.
Therefore, always pre-drill MDF boards first! Pre-drilling prevents the board from cracking when the screw is screwed in. Alternatively, you can use wooden dowels into which you then screw the appropriate screws
What can I do if my MDF board smells badly?
Wooden objects tend to have a strong smell, especially when they are new, which can be perceived as unpleasant by some people. With MDF boards, there is also the formaldehyde glue. This chemical substance has a very intense smell. So what can be done to counteract the smell?
One way to stop emissions from MDF is to enclose it in paint or varnish. This way, the bad smell can be masked. If you don't want to varnish the MDF board, you can use common household remedies such as coffee or baking soda to neutralise the smell. Rubbing in vinegar also helps against the penetrating odour. In the case of strong acrid odours, the manufacturer should be contacted, as a strong acrid odour may indicate that too much formaldehyde has been used. This can be very harmful to health.
