Wood – the most sustainable material in earth that can forms anything and everything. Recently, wood has gained much more popularity in construction segment as engineers and woodworkers tend to prone to the woodworking. The natural look of wood lends itself both indoors and outdoors to a range of styles and it feels warm and cosy, making it building material that is popular with many customers.

But according to researchers, due to severe use of wood in indoor, outdoor and construction industry, wood is highly need to be coated properly. Therefore, appropriate and professional wood coating takes the centre stage here. Recently, WAGNER comes with the report where they clearly mentioned their ability to save wood by offering proper wood coating solutions.

To ensure that constructions can withstand stress from use or the weather, you – whether you are a painter, carpenter, joiner or woodworker – need to coat the wood. You can read here about which coating materials there are, what to look out for and how you can apply wood coatings with a WAGNER spray device.

Let’s have a proper enlightenment.

WOOD – Why does it need to be coated?

Wood is a hygroscopic material. This means that wood absorbs moisture from its environment (rain or humidity in the air). If there is too much water, the wood swells and is damaged. Accordingly, if left untreated, wood has low dimensional stability. In other words, it does not withstand changing environmental conditions well. Wood is also an ideal home for various pests. On example is the larvae of the common rodent beetle, or woodworm, a dry wood pest that eats its way through structural timber.

Outdoors, moss or fungus can attack wood by feeding on the lignin and cellulose within it, which compromises the wood’s structural integrity. This not only poses a potential danger to people nearby due to the weakened stability, but it can also be harmful to health. Additionally, wood is highly flammable. Applying a fireproof coating can mitigate this safety risk.

Since pests and weather can dramatically impact the stability and longevity of wooden components, it is essential to coat timber appropriately for its intended use. Apply coatings that are suited to the specific type of wood and its application to ensure optimal protection.

How to coat wood with our spray devices?

Nowadays, the application of varnishes and glazes to wood surfaces is primarily carried out using professional spray technology. WAGNER spray devices make it exceptionally easy for you, as a tradesperson, to spray wood coatings.

Various methods are available to help you do this: AirCoat / Airmix, Airless or XVLP / HVLP. If you carry out varnishing work on wood on a particularly frequent basis and very professional scale, we recommend the AirCoat method. Find out here how you can quickly coat and perfectly protect a wood surface in just 5 steps:

Step 1: Surface inspection and preparation
Step 2: Preparation of the selected wood coating
Step 3: Select the right gun and matching filters
Step 4: The correct coating – spraying wood preservative
Step 5: Cleaning the spray device

What makes the application of wood preservative using spray technology so professional?

Perfect surface finish

The surface’s existing structures, such as reliefs, remain perfectly preserved with spraying. It produces a homogeneous and closed structure that is high-quality, resilient and long-lasting.

Working speed

Even when accounting for the time spent cleaning the work materials, spray technology allows you to coat a larger surface area more quickly than using a brush or roller. Additionally, spray technology significantly speeds up the coating process for complex surfaces.

Ideal functionality of the coating

Spray application ensures that even the tiniest corners and edges are coated evenly, which allows the coating to be as effective as possible.

Perfect adaptation to local conditions

Varnishes, glazes and other wood preservatives need to be at room temperature for optimum processing. If this is not possible on site, temperature-controlled spraying allows the material to be heated very conveniently to the correct temperature.

What coating materials are available for wood?

There are various materials available for coating wood. They can be differentiated into film-forming wood preservatives, oils and waxes, synthetic resins and other coating materials.

The film-forming wood coatings include varnishes and glazes. The difference lies in the two coating materials’ permeability. A protective glaze for wood still allows the diffusion of water, in other words, the wood is still able to give off moisture. Varnishes, on the other hand, completely seal the surface so they become impermeable.

Both varnishes and glazes can be used to achieve cosmetic effects. Chemical substances such as UV protection, fungicides or pesticides are often added to varnishes and glazes. Today, the trend is increasingly moving towards solvent-free varnishes and water-based glazes since they are better for our health and the environment.

Oils and Waxes, however, these substances are often based on natural ingredients and are also used for coating wood: Furniture is usually treated with these types of material. They close the pores and form a seal that protects against stress, marks and moisture.

Synthetic resins are industrially manufactured resins. Once they have hardened, they form a solid plastic that does not melt. Synthetic resins, just like varnish, are also used to create a complete seal and also protect against mechanical stress. Epoxy resin is used to coat wood and make it waterproof. Coating wood with epoxy resin is a practice that is used for plywood, laminate or even in boat building.

The choice of wood coating completely depends on the number of several necessary factors:

The WAGNER spray devices are ideal for spraying all of the wood preservatives.

Which WAGNER spray devices are suitable for wood coating?

WAGNER devices like: AirCoat, Airless or XVLP are the perfect to allow to coat wood precisely and quickly.
