OSB or Oriented Strand Board, has become a popular alternative to traditional plywood.
While it offers a number of benefits, many are still concerned whether it’s robust enough if exposed to water or high levels of moisture.
Image credit: Wikipedia
OSB was invented back in 1963 by Armin Elmendorf.
This wood sheeting is made from 95% wood chips and 5% adhesive.
Indeed, OSB is made by mixing resin with strands of young wood to achieve a hard board.
This is then waterproofed to increase its durability.
This is very important especially if the OSB boards will be used in outdoor applications.
OSB boards are becoming quite popular as they are considerably thicker than plywood boards, and thus stronger than its counterpart as well.
OSB boards are used in various applications, including flooring, roof decks and even to make furniture.
OSB is made using waterproof resin adhesives.
The process that such boards undergo to be manufactured makes them highly water resistant.
This is due to the fact that the voids between the strands are very small.
Whatever gaps may be present, they will be filled with heat-cured waterproof resin adhesive and wax, in order to bond the wood chipping to each other.
As a result, all the wood strands in the board are coated, making the board water-resistant.
The edges are also treated with a sealer.
This gives the board additional moisture protection.
Even though OSB boards undergo such a process during manufacturing, it’s still best to fortify them with additional moisture protection before using them in an actual application.
This is because OSB boards are not exactly 100% waterproof, but are more accurately considered reasonably water-resistant.
It’s impossible to prevent water absorption completely as at the end of the day, this is a wood-based product.
However when compared with other types of materials, such as MDF boards for example, OSB is considerably better when it comes to moisture resistance.
Yes, it is a good idea to waterproof seal OSB boards.
When buying OSB boards, make sure that they have the ‘waterproof’ mark applied.
This is found on the back of the boards.
Despite this, it is still recommended to waterproof OSB boards, especially if they are going to be in an outdoor setting.
Image credit: Wikipedia
Generally speaking OSB boards are able to withstand 4 weeks of continuous moisture exposure.
There are even some which are rated to withstand up to 200 days of exposure without sustaining any damage.
However, if untreated cut boards are exposed to rain or standing water, the moisture absorption will be too excessive, so there’s a chance that swelling could occur.
If water exposure is prolonged, delamination is highly likely to result.
Therefore, OSB boards should not be left to get wet unnecessarily.
Painting or staining, and undergoing a waterproofing treatment is highly recommended, especially if the boards will be in an exterior setting.
Long term moisture exposure should be avoided, and if possible the boards should be covered or protected.
OSB board can withstand exposure in an outdoor setting quite well.
It is important that if it’s going to be left outdoors, you choose OSB boards that are highly moisture resistant.
Hence, the boards should be packed with more strands, resin and wax to have superior moisture resistance level.
Such boards are classified as class 3 and they are the best type for humid conditions.
Such boards should also be given an additional layer of waterproofing as described above.
This offers them more resistance against moisture and water, which will inevitably be more present in an outdoor setting.
If OSB boards are going to be left outdoors, ideally they should be covered to protect them from rain and moisture.
An odd rain shower should not cause much damage.
But if they’re exposed to several hours of rain, then they could end up swelling.
Covering with tarpaulin is also a good option to protect OSB boards from rain.
Another option is to spray them with exterior grade paint or a water sealer.
This is especially important for any cut edges on the boards.
If the boards have been used on roofs, they could be covered with roofing paper.
If they are used on walls they could be covered with a weather resistant barrier before siding.
Priming, painting or staining after construction has been completed is important.

Make sure that you plan carefully before cutting the boards.
This is because whenever you cut, the sealer that was at the edges will be removed, and as a result moisture can be absorbed more easily into that area.
So waterproofing will need to be done after you’ve made the required cutting.
To make OSB boards more water resistant you can paint them.
If you are going to do this, it is best to paint them prior to carrying out the waterproofing process.
This will enable the paint layer to also be protected from water and moisture.
You may choose either latex-based or oil-based paint.
To waterproof OSB boards, choose a good quality waterproofing solution from any local hardware store.
Check that it can be applied to wood.
The solution can be applied by using a paintbrush, while making sure you coat all the board.
It is best to apply a second coating, and allow around 12 hours for the waterproofing to dry sufficiently.
OSB is a timber construction material that’s highly resistant to moisture.
When compared to other types of wood panels, it has a much slower moisture absorption rate.
Additionally, it can be water and weatherproofed for additional resistance, especially if it is going to be used outdoors.
This can be done very easily by using water repellent paints or stains.

Nowadays, MDF is a commonly used material for furniture as well as for various construction projects.
This affordable engineered wood material is very versatile, easy to cut and quite durable too.
Thanks to its smooth surface it can also be painted, and that is just what we will be focusing on here.
Painting MDF calls for a good understanding of the material itself, as well as being aware of certain things to make sure that it produces a good looking finish.
Image credit: Pexels
Often the answer to this question is debatable.
MDF can be painted as long as you are careful how to go about it.
MDF is basically made up of a combination of sawdust and resins.
These are bonded together by means of a process involving very high heat and pressure.
MDF is free of knots, rings and grains which are present in real wood.
Consequently it has a smooth surface which can be painted.
However one needs to be extra careful when it comes to the uniformity that can be achieved when painting MDF.
This is because the edges are considerably porous, and so they require more prep to achieve the best results.
Moreover, since MDF is porous it is not a good idea to use water-based products for the first coating.
Any painting project requires some preparation to ensure the best results.
And one needs to make sure that the right paint is used, coupled up with the right approach.
MDF has a 150 grit on the front and back, whereas its edges are more rough and porous.
So it is crucial to ensure that they are properly prepared in order to create a uniform substrate which is ideal for the paint to be applied upon.
We shall be tackling this in more detail hereunder.

The following are some tools and materials you will need to prepare MDF for painting, as well as to proceed with painting it.
The first step is to make sure that you carry out preparation of the surface properly.
This includes sanding, cleaning and sealing.
Sand down the MDF surface using a light key sandpaper, such as 120 grit.
Sanding will improve the adhesion of the MDF to paint.
The MDF boards will have dust, dirt or other grime on them, and so it is important to clean them before moving onto a second coating of priming and subsequently, painting.
You can use a universal cleaner which can work as a degreaser as well as a cleaner.
This can be wiped down with a cloth, so as to properly clean the surface of the MDF boards.

It is very important to prepare the edges properly, especially since as mentioned earlier, MDF boards’ edges are rougher and more porous.
Hence they will absorb more moisture than the back or the front of the boards.
Preparing the edges well also ensures that they will be sealed and better able to accept the paint in a way that will better match the smooth surface of the MDF.
Prior to sealing, it is important to sand them by using a 120 grit sandpaper.
Make sure to wear protective goggles and a mask while doing so.
When the edges have been sanded, apply prime the MDF so as to seal them.
This is an important procedure before painting MDF boards.
Once the primer has been given enough time to dry, sand down the edges again.
If the edges are going to be visible, you will want to keep them as smooth as possible.
So, if there are any parts which need to be smoothed out, you may wish to apply some wood filler and rub it down.
Alternatively, you may wish to apply some MDF edging tape.
Apply a second coat of primer, while making sure you apply it as evenly as you can.
This will be the final base before the painting and so a smooth result is important.
It is best to use a solvent-based primer.
This is because a water-based one might cause the wood fibres to swell, and as a result the surface might appear to have a raised grain even though you sanded it.
The primer can be applied using a roller, a brush or a spray gun, depending on your preferences and the type of project.
Image credit: Pexels
Painting can be carried out by means of a mini roller or a paintbrush, depending on what you prefer.
A 4 inch roller is generally the best option for most MDF painting jobs.
A foam roller will give a smooth finish, whereas a short pile roller will add some texture to the coating.
On the other hand, if you are painting MDF with detail it is better to use a 1 or 2 inch brush so as to attain a better finish and a thin, even coat.
Allow the first coating of paint to dry completely.
Generally it is better to apply a second coating of paint so that the MDF has a good paint film.
Considering that MDF is porous, you may require more paint than you thought was necessary.
Hence, at least two coatings of paint are necessary in most cases.
You may also need to apply a third coating, especially to the edges.
If the paint looks a bit patchy across the board, this is a sign that another coating of paint is required to achieve a better result.
It is also a good idea to lightly sand between each coating, and wipe down the boards every time so as to remove the dust.
Applying a sealant is optional, however it is recommended especially if the MDF will be subjected to heavy traffic or exposed to scuffs.
Sealing will help to preserve the finish, as well as add sheen to the MDF.
Painting MDF does not mean that it will make it waterproof.
However, since you will be applying a film on the surface, it will help to considerably reduce water damage as it will be better able to resist moisture.
In order to fully waterproof MDF you will need to paint it with a dedicated water-repellant.
This is recommended in case the MDF is going to be outdoors, for example.
Since painting provides additional water resistant to MDF, it can help to prevent it from remaining damp when exposed to water.
Hence, it could prevent mould from emerging.
Painting MDF is thus highly recommended if the MDF furnishings will be placed in rooms that are prone to high levels of moisture, such as bathrooms and garages.
Priming MDF is optional.
You can paint MDF without having applied a primer before, however results will not be as good as they would be if primer were applied first.
This is because the MDF will absorb the paint much more quickly, and so you will end up using more paint.
Applying primer before painting can lead to smoother and better results.
MDF is made up of a mixture of dust, fibres and glues.
As a result, when it is cut, these will become airborne.
Should they be inhaled, they could be harmful.
Therefore, when sanding or cutting MDF it is very important that you wear a mask and eye protection to safeguard yourself.
Both oil based and water based paint can be used for MDF.
And as with anything else they have their respective pros and cons.
Oil based paint is considered to be more suitable than water based paint for MDF.
This is because oil based paint can lead to a higher quality finish, more sheen and better durability.
Conversely, water based paints dry more quickly and contain less VOCs. They are also easier to use and to clean up than oil based paints.
Making sure that you follow the various steps mentioned to properly prepare the MDF prior to painting will help you to attain a better result.

If you’re planning to design a kitchen renovation, or you’re in the process of ordering a new kitchen, you may be be considering the types of materials that you can choose from.
While kitchen cupboards can be made from a variety of materials, it’s important to be aware of the pros and cons of each.
This will help to better position yourself when choosing a material that suits your needs and budget, as well as offering good value for money.
After all, buying or renovating a kitchen is not something that you do very often.
So it’s best to choose appropriately for your circumstances and needs.

Melamine faced chipboard is the most popular material for kitchen cupboards.
In fact, the majority of kitchen cabinets in the UK are made from MFC.
Chipboard, or particle board as it’s sometimes referred to, is made from small chips of wood.
These are glued together, and compressed under high pressure to ultimately form a panel.
Then this is laminated with a melamine outer surface.
Melamine is essentially decorative printed paper.
This layer is soaked in melamine resin and then fixed to the chipboard to achieve the final product.
MFC strikes a good balance between several advantages, while remaining considerably affordable.
Let us delve a bit deeper into this type of material.

Polyester kitchen cupboards are another option, though not quite as popular as MFC.
This material is made up of melamine which is blended with pine fibres, and then coated with polyester film.

Solid wood is not a particularly popular construction material for kitchen cupboards.
This is mainly due to the fact that natural growth and contraction of solid wood makes them rather unfeasible for kitchens.
Having said that, solid wood kitchens which are freestanding, and not made to be fitted from wall to wall, are sometimes made from solid timber.

Plywood is becoming increasingly popular for kitchen cabinet carcasses.
Even though it generally costs more than MFC, it is structurally far stronger.
This offers advantages for fixing and assembly.
Moreover, thanks to this flexibility, it is easier to make modifications.

Chipboard kitchen cupboards can also be covered in real wood veneers.
That is, by a thin layer of real wood which is glued onto the chipboard panel.
As a result, besides the stability that chipboard can offer, there is also the added advantage of the natural variations of real wood.

MDF is made from small particles of wood fibre.
These are mixed with wax and resins.
Using MDF offers various benefits, and it looks very nice.

High pressure laminate is quite similar to melamine.
It is manufactured in multiple layers, which are pressed together by means of very high pressure, thus the name.

While definitely not as popular as the other materials mentioned above, metal is also used to make kitchen cabinets, especially for professional catering establishments.
Now that we have comprehensively covered every type of kitchen cupboard material available, including their pros and cons, we hope that you are now in a better position to make a well informed decision to choose the best kitchen cabinets.
As you will have discovered, each material has certain advantages over the other.
So it’s important to choose wisely so you fully benefit from longevity and value for money, plus get the look and finish you desire.

Whilst you design a kitchen, you will need to make an important decision - which type of kitchen cabinets should you choose?
You want a material that can offer you quality and durability, but also be within your budget.
The following guide should offer you some insight about different types of kitchen cabinets you could consider, along with their respective pros and cons.
When it comes to kitchen cabinet materials, there is a wide range of options.
You will need to take into account the density of the material in particular, as this will have a considerable impact on their lifetime.
MFC is the most basic material you can opt for.
It is one of the most affordable options, and yet it is relatively strong.
The chipboard core is composed of scrap wood, sawdust and paper.
It is then faced in a melamine laminate.
The surface is moisture resistant.
However, it is important to avoid moisture getting in because even if the carcass is generally well sealed to prevent the possibility of expansion, it is still best to be careful.
MDF is a popular option.
It is considered to be somewhat better than chipboard, and it is generally slightly more expensive than MFC too.
The main reason for this is that MDF is denser and more durable.
It also has a smoother and more moisture-resistant edge.
MDF is made from felted wood fibres.
These are bonded together by means of extremely high pressure.
MDF is free of saps and knots, and one can find various finishes to choose from.
Another variety of MDF is Veneered MDF.
This consists of MDF boards which have been improved with a thin veneer of timber applied on either one or both sides.
This reduces the chances of warping and gives a nice look to the cabinets which will look as if they are made from a single piece of wood.
Plywood is made from layers of hardwood which run both lengthwise as well as crosswise, thus making it stronger.
It is a stable and solid material which is often used by bespoke cabinet makers.
Plywood is very resistant to damage such as dents, dings and blow-outs.
One can also find MR ply, which is moisture resistant.
This is important especially for a kitchen, particularly in close proximity to the sink and taps.
Plywood is generally faced with birch or oak. It can also be laminated or painted.
In many cases the cabinet boxes are built either of plywood.
For robustness purposes, cabinets that have full plywood sides and backs are the best.
This is because they will be better able to resist any damage caused by moisture as well as better handle the weight of the countertops.
Kitchen cabinets can also be made from solid wood.
However, it is worth noting that this is not such a popular option for the carcasses as they could warp over time.
Other than that solid wood such as solid oak and beech are considered to be popular options as they are durable and of superior quality.
The type of cabinet construction you are going to opt for is another key decision.
Flat pack kitchen carcasses are inevitably cheaper and easier to transport and store.
As a result, they will cost much less than solid carcasses.
These are generally made on a CNC machine, and consequently all holes and screws will line up.
Hence they are very easy to assemble.
Flat pack carcasses may be cheaper.
However, it is important to note that the cost of assembly will need to be factored in, unless you are willing to see to it yourself.
Speaking of installation, there is a higher risk that this could be done incorrectly.
As a result, the joints will be less solid.
In some flat packed kitchens, the joints are wooden dowels that are glued into holes, or secured in the holes by means of two or three screws.
In both cases, one cannot really say that they are that strong.
However, if the wooden dowels are secured in holes by means of two sets of metal studs and cams, they will be considerably strong as the dowel will be well secured in place.
There is also the problem that if there are any missing parts there will be problems as well as delays.
Solid or rigid carcasses are structurally better.
They will also be fitted quite easily.
Generally if one is looking for less downtime between removing an old kitchen and having a new kitchen fitted, rigid carcasses are preferred.
There is also much less risk that there will be missing parts or components, and so delays can be avoided.

Many kitchen companies nowadays offer a kitchen with standard units, available in diverse sizes.
Carcasses are generally made in standard European sizes which are labelled by width, such as 300mm, 500mm, etc.
The main advantage of standard units is that they will generally conform with appliance sizes, making it easy to fit them in the cabinets.
Alternatively, you may wish to opt for a kitchen manufacturer who will be able to design and make bespoke cabinets.
In this case the carpenters and joiners will be able to fit the cabinets according to the requirements of your room.
Needless to say, if you opt for bespoke cabinets you will need to be willing to pay a bit more.
However there is the advantage that you have more freedom of choice and greater flexibility.
There are various styles you may wish to consider for your kitchen cabinets.
This is probably the most timeless option.
The cabinet doors will be solid and painted, featuring a frame and veneered centre panel.
There are inevitably several different colours that you can choose from, depending on your particular preferences.
Be it a fresh white, cream or soft pastel colours, or relatively cooler tones such as blue or green, the sky is your limit with shaker kitchen cabinets.
Slab kitchen cabinets consist of a smooth canvas which is then customised according to one’s preferences and budget.
A matt finish over gloss is a popular option as it calls for little maintenance.
Slab door designs which are handleless are becoming quite popular.
They are easier to keep clean and look smooth and sleek, which is a style many prefer.
High gloss finishes are considered to be favourites too.
With flowing lines, and free from any fussy features or finishes, high gloss cabinets stand out with their colours and finishes.

Sometimes the importance of planning for the fixtures and fittings goes underestimated.
The plinths or kick-boards for instance, are important as these will ensure that the unit legs are covered.
These will run all along the floor beneath the kitchen units.
Higher up, you will need to think of the cornices.
These will make the upper frame look neater as they will hide the cabinet tops.
The drawers and runners are very important.
You should consider how these will be located, so as to have a neater layout.
It will also ensure that any items stored within do not end up going all the way to the back and be hard to locate.
It is recommended that you always check the load capacity of the runners as this will affect the size of the drawers.
Inner storage solutions are another important consideration.
Nowadays there are a variety of options, some of which are functional as well as decorative.
Some ideas include corner storage carousels, pull-out swing ladders and wicker drawer baskets.
It is also a good idea to consider soft close cabinet hinges to safeguard the doors and drawers from getting damaged in case they are slammed shut a bit too forcefully.
Such hinges and runners are not expensive and so they are worth considering.
Last but not least you will need to choose the handles or knobs.
You may also wish to consider bars.
Otherwise there is also the option to go completely free of any handles too of course!
While traditionally solid wood used to be considered as one of the best materials for cabinetry, nowadays there are other options.
Engineered wood products are considerably reliable as well as more affordable.
There are also numerous fixtures and fittings to choose from, and needless to say, countless styles too.
While the aesthetic features of cabinet doors are important, it's highly recommended that you pay close attention to the properties of the materials used as well as the interior construction of the cabinetry.
Indeed, while the doors are the most visible and character-defining parts of the kitchen, the structural body of the cabinets is of great importance too.

In the past, plastic laminate was very popular due to its various positive attributes.
Later, High Pressure Laminate (also known as HPL) was introduced to the market.
One can say that HPL is a descendant of the original plastic laminate as both have various things in common, but with some added benefits.
Read on to find out more, or use a jump link below to skip to a desired chapter:
High Pressure Laminate board is a decorative surface material which is considerably durable and resistant to wear.
HPL boards are also great in terms of their properties, as they are fire resistant and chemical resistant.
HPL is laminated to panels or boards by applying various adhesives.
Generally MDF or particle boards are used as they are considered to be ideal substrates due to their composition, stability and durability.
Some HPL can also be post-formed around the edges by applying heat.
High Pressure Laminate belongs to the high-tech group of high pressure decorative laminates.
The highly compact and aesthetically appealing composite sheet that results from the production process offers a highly resistant surface that is ideal for various applications.
High Pressure Laminate is produced by saturating several layers of kraft paper with phenolic resin.
Afterwards, printed decor paper is placed over the kraft paper, and a pressing process commences.
Due to the heat and pressure applied, which exceeds 1000 PSI, the two become fused together.
Phenolic resin and melamine resin are thermoset plastics.
As a result, the curing process leads the resin to turn into plastic.
This happens due to a cross-linking process, whereby the paper sheets are converted into one laminated sheet which is considerably rigid.
This bonding process is strong and irreversible.
This is the main reason behind the durability of HPL boards.
The key properties of HPL boards are:
These are some of the reasons why HPL is considered to be a good choice when compared to other materials.
In recent years, Double Belt Press processes are used to produce Continuous Pressed Laminate (CPL).
This is a decorative paper that is impregnated with resins which have been fused together with high heat and pressure.
The thickness ranges between 0.4mm to 1mm, and they come in various lengths or in the form of a continuous roll.
Another variety is the Flexible CPL.
In this case, flexible thermosetting resins are impregnated in the decorative paper.
Like CPL, these are fused together by applying very high heat and pressure with resin-impregnated backers.
However, this type is intended for formable decorative laminates such as edge banding and profile wrapping.
The thicknesses are between 0.2mm and 0.4mm.
There are various types or grades of HPLs.
They are intended for different uses and for particular performance requirements.
General purpose is the most common and widely used HPL board.
They are used both for horizontal as well as vertical surface applications.
The thicknesses range between 0.71mm to 1.22mm.
These can be formed around the curved edges by applying high heat and restraint.
The maximum thickness of this type is around 0.97mm.
They can be formed to very small radii of as little as 9.5mm.
This type of HPL is used for backing, so it doesn’t include a decorative surface.
It tends to be slightly thinner than the decorative HPL varieties.
Backer also includes the regrind, that is reclaimed HPL that has had the decorative sheet sanded off.
Special purpose HPLs include laminates that are chemical resistant, fire-rated and electrostatic dissipative.
An example is cabinetry liners which have these properties and are very high-wear.
In order to increase the resistance of particleboard or MDF, HPL can also be applied.
Hence it not only helps to improve the aesthetic appeal thanks to its decorative value, but it also improves the physical performance of the substrate.
For instance, a standard shelf made from particleboard can carry 45 lbs per square foot.
This same shelf is however able to hold 85 lbs if it’s overlaid with HPL.
Considering the various positive properties and advantages of High Pressure Laminate (HPL), it is used in various applications and products, including:
With various colours and finishes to choose from, and offering a myriad of positive properties, HPL has become a very popular material.
It’s increasingly being used in a variety of applications, both indoors and outdoors.
Easy to clean and virtually maintenance free as it is highly durable and resistant, this material is a relatively recent innovation which is gaining considerable popularity.
One can safely conclude that it is a superior quality material which, thanks to its positive attributes, has gained a considerable advantage over traditional alternatives.
