Particleboard , by contrast, makes use of ordinary sawdust rather than fibrous wood, and as a result, is less water-resistant and offers less structural strength than MDF. Medium density fiberboard, or MDF, is a manufactured product composed of wood fibers mixed with resin and wax, and pressed into flat panels under high temperatures and pressure.
It is used as a building material in residential and commercial buildings. Keep this in mind when building with it. Other than this slight drawback, MDF is an excellent building material, as it accepts glue bonds very well and joins securely with nails and screws with minimal chances of fracturing. It is best to cut MDF outdoors, as it creates a lot of dust. It is also smart to wear a respirator when cutting or sanding MDF, to avoid expose to fine dust and to the resins used in manufacture.
When exposed to moisture, unfinished MDF can swell and lose strength, so in applications where moisture expose is a possibility, exterior-grade plywoods are a better choice.
Because MDF accepts paint so well, it is often used in visible applications, such as in cabinet carcasses that will be painted. Particleboard , on the other hand, does not accept paint very well, and so is more commonly used in hidden locations, such as for underlayment for carpeting or other types of flooring. Use solvent-based primer The face of MDF is smooth, but the edges are fuzzy and need to be primed before painting to avoid a sandpaper effect.
Protect your face MDF work produces a sandstorm of fine, powdery dust that infiltrates everywhere and everything, so try to cut and rout MDF outdoors.
Keep an extra saw MDF tends to dull saw blades quicker than most woods or plywood so have an extra saw blade handy. Sand your edges Cutting MDF creates sharp, open edges, so you will need to sand all cut edges, which can usually be accomplished with a fairly light-grit sandpaper, such as grit. Get Social.

The best way to cut the risk of infestation is proper chemical treatment. Make sure that the unit has an up-to-standard finish or otherwise your investment might be at stake. Woodworms, anobiidae deathwatch beetle and the common furniture beetle , bostrichidae false powderpost beetles; powderpost beetles , longhorn beetles old house borer, house longhorn beetle; anoplophora longhorn beetles known as fera; wharf borer , bark beetles, moths, carpenter bees, carpenter ants and wood wasps are the most wide-spread.
Bare in mind that even getting rid of a woodworm is a hefty battle alone! Imagine if you have to deal with two, three or more pests at the same time! Inspect the finish! The price tag can be hefty. While not all types of solid wood are expensive, most are. Species like white oak and walnut and cherry will surely cost you a chunk, not to mention that others are scarce in supply, such as teak and mahogany.
Generally, pricing depends on durability, aesthetics and availability. In theory, it is a material that consists of recycled leftovers from when solid wood was cut — fibres and resin all mixed up with wax. In terms of consistency, MDF is more compact that plywood but not when it was initially presented as a product.
A few years back, MDF was less durable than solid wood, but technology and manufacturing have advanced and high-end MDF boards are as durable as natural wood. Different classes of engineered wood are based on the size of the board, its consistency, the type of glue and of course, the type of fibers used. MDF is hard to both flex or crack. Although MDF is technically made out of wood, its structure is absolutely different. If you try to bend a MDF board it would rather snatch then warp.
This is why engineered wood has the advantage of being resilient to moisture unlike its opponent. Of course, if you sink it in water, sooner or later the board will succumb to damage.
But if you expose it to airborne moisture, the piece will expand and shrink as a whole while keeping the overall integrity and shape intact. MDF is more affordable and easier to supply. Generally, MDF boards come at a lower price than natural wood. Of course, there are a few exceptions if you compared high-end MDF with some of the less pricey types of timber. Another great benefit of engineered wood is the fact that you can find it easier than i. MDF is easier to paint and seal.
Contrary to solid timber, engineered wood lacks any specific grain or texture. The advantages of engineered wood for cabinet doors are undisputable. The flexibility of manufacturing has offered interior designers to choose between flat-paneled, partially, fully overlay, inset, euro-styled and raised designs. Many types of MDF offer extra resistance to moisture, which is crucial for kitchen and bathroom furnishing.
Engineered wood is easy to damage. One of the main differences between solid and engineered wood is the surface. If you try to sand it you will reach the fibre-waxed core and thus hurt the overall integrity of the board. Repainting flat pack units requires a gentle and delicate approach.
Contrary to solid wood, where a bit of sanding can hide dents and scratches, damage on MDF is permanent. MDF is heavier. Many falsely assume that solid wood is heavier but truth is MDF does weight more. This is the main reason why fitting a flat pack kitchen requires more anchors and extra support, especially when wall-mounting cupboards and shelving.
It is also the reason why many furniture designers will only leave cabinet doors MDF and design the rest from solid wood. This is why you should not leave MDF units in proximity of heaters, radiators, fireplaces, ovens, stoves as well as out in a hot summer.
