Outdoor woods (cladding, garden furniture, shutters) are subject to climatic aggressions (UV, bad weather). If the wood is not treated, it will deteriorate over time (deformation, swelling, cracks). To prevent this, you can protect them with wood paint. In addition to providing protection, paint allows you to colour and gives your wood a unique appearance. In this article, we will present the advantages of paints and explain which paint to choose for exterior wood.
THE ADVANTAGES OF EXTERIOR WOOD PAINTS
Specialised paints for exterior wood have several advantages :
They protect outdoor surfaces from UV, weather or deformation. Paints are products that opacify the wood, which helps to protect outdoor wood against UV rays. Painting outdoor wood means protecting it to increase its lifespan.
In addition to protection, they can add a decorative touch to your outdoor woods by customising them to your desires. Anova Bois' Exterior Wood Paint PBE900 is available in more than 200 shades of colour. It is a ral paint for exterior woods (RAL colour chart) that allows you to find exactly the shade that suits you. If you want a white colour, Exterior Wood White Paint BLE900 is for you.
Generally, paints for exterior wood such as the Anova Bois range are microporous. They allow gas exchanges between the wood and its external environment. The wood can thus evacuate the natural humidity it possesses.
They have a fluid, elastic consistency, which allows the product to become impregnated into the wood and not flake off over time.
Good to know : paints are products that opacify the wood and mask the natural grain of the wood. If you wish to preserve the natural grain of the wood, we advise you to turn to the saturators in our range..
HOW TO CHOOSE A PAINT FOR EXTERIOR WOOD ?
THE CHOICE OF THE TYPE OF PAINT FOR EXTERIOR WOOD
For painting exterior woodwork, there are different paint formulations available :
Acrylic paints for exterior wood are water-based (water-based formulation) and microporous. These paints such as Exterior Wood Paint PBE900 or the Exterior Wood White Paint BLE900 are neutral for the environment and the applicator. They are the most environmentally friendly wood paints. During application and drying, they do not emit volatile organic compounds. Tools are cleaned with water, without chemicals, without White Spirit.
Glycerol paints for exterior wood are oil-based. They offer maximum resistance to UV, weather and mould. However, they are diluted with white spirit, have a long drying time and emit a strong odour. These paints emit volatile organic compounds and are therefore not neutral. They are the most polluting paints. Glycerol paints are not microporous, so there is a greater risk of flaking over time. Tools must be cleaned with white spirit. These are the paints with the strongest hold, so they will be the most difficult to remove if you wish to strip them.
Alkyd paints for exterior wood are the intermediary between acrylic paints and glycerol paints. Like acrylic paints, they are water-based and microporous. Tools can also be cleaned with water. On the other hand, they take a long time to dry and turn yellow over time. However, alkyd paints contain synthetic resins in their composition.
THE CHOICE OF THE COLOUR OF THE EXTERIOR WOOD PAINT
Outdoors, the paints are exposed to UV light. They can lighten over time under the effect of the sun. We advise you to choose a shade one tone above the desired result.
An intense shade contains more pigments than a lighter shade, so it will protect the wood more. In fact, the more pigments the paint contains, the more it will protect the wood.
THE APPLICATION OF EXTERIOR WOOD PAINT
CHECK THE CONDITION OF THE EXTERIOR WOOD
Before painting your exterior wood, it is recommended that you carry out a few checks on the wood :
Is the wood healthy? Outdoor wood paints are applied to clean, perfectly dust-free wood. If your wood seems to have deteriorated, you can restore it by filling any cracks, for example. If the wood is attacked by wood-eating insects, termites or fungi, you can pre-treat it by applying an insecticide-fungicide.
Has the wood been finished in the past? If the wood has already received a previous finish such as stain, you must remove this finish by sanding. If the wood has already been painted, it is advisable to strip off old paint that is chalky, flaky or not very adherent. Well adherent paints can be sanded or simply washed, depending on the type of paint used. If you have any doubts, do not hesitate to contact us from our contact section.
APPLY THE PAINT
Wood paints are easily applied in layers in the direction of the wood fibres. Paint the exterior wood evenly for a better finish. The paints in the Anova Wood range, such as Exterior Wood Paint PBE900 are designed according to rich formulations and are of professional quality. They can be applied without an undercoat.
Avoid applying exterior wood paints when the weather is too wet. From a technical point of view, the moisture content of the wood should not exceed 17%. Having good weather conditions will help to avoid problems with adhesion of the product during application and ensure that drying will be optimal.
