If you don’t want to allow Ayous wood to turn gray or want to give it an opaque treatment, you have several options. The various options are described below. If you leave the wood untreated, it will gray to a beautiful, uniform gray color with the wood grain remaining visible.

• Treat with oil

The first option is to treat the wood with oil. An oil creates a non-film-forming layer that leaves the wood structure beautifully visible. It should be noted that the wood is best treated with a non-transparent oil. A transparent layer is still very vulnerable to UV rays from the sun and other weather influences. However, treating the wood with a pigmented product will block sunlight from direct contact with the wood.

Repetition: It is recommended to repeat the treatment every 1 to 2 years.

Benefits of an oil:

• Preserving the appearance of the wood. The wood grain remains visible.
• Since it is not a film coating, it cannot crack.
• Easy to apply.

Tip: To ensure good durability, you should treat the wood completely all around.

We recommend Woca Exterior oil. Further information can be found on this page this page.
Usage: 8-10 m2/l Packaging: 750 ml and 2.5 liters Colors: available in 12 colors

• Treating Ayous with a wood stain

We work with Remmers. Our wood stain has a 3-in-1 effect: impregnation, primer and primer and top coat. The stain protects your wood from moisture and has a preventive effect against blue rot, mold and algae. The stain should be applied in at least 2 coats and has a drying time of 2-3 hours.

We recommend the Remmers Aqua HSL-35/m 3in1.

Usage: 5 m2/l Drying time: dust dry after approx. 1 hour, can be painted over after approx. 2-3 hours Packaging: 2.5 liters Colours: available in Ayous colour.

• Impregnating Ayous wood

Another way to prevent the wood from turning gray is to pressure treat the wood. The wood receives the same treatment as garden wood, which is impregnated green. With Ayous, however, due to the dark color of the wood, the effect is not green, but rather dark brown. The impregnation is done mechanically. The wood is placed in a cauldron and the impregnating agent is pressed into the wood under pressure. Due to the brittle structure of the wood, this happens very effectively and the wood is soaked quite well with the agent.

The reason this is often done is because it is inexpensive. The cost of impregnation depends on the volume. For a small facade under 1 m3 the cost is from €150 plus VAT. This impregnation is done externally, so additional transport movement should be taken into account.

For comparison, for a facade of 100 m2:

• Treat the wooden facade yourself with oil: 4 cans of Woca oil at €75 each, a total of €300
• Machine coated/painted in a color of your choice. Per m2 €18 = €1800 in total
• Impregnation of 1.8 m3 = approx. €240 in total plus additional transport of €125 each

WARNING: This will delay graying by a few years. This depends heavily on the direction in which the facade is located. On the north side the brown color will remain for more than 5 years, while on the south side it will fade more quickly in full sun and the first signs of graying will become visible after just 2/3 years.

Should you do it yourself or outsource?

You can carry out the treatment of your Ayous wooden facade yourself by adding our stain or oil to your order. You can also choose to have your wooden facade treated by machine. The advantage of this is that the wood can be treated more evenly by machine than by hand, and you don’t have to work with it.

Machine treatment of your wooden facade is possible starting from 25 m2 at a price of €15 per m2.
