Are your shutters, partitions, cladding, gates, fences, garden sheds, windows, pergolas looking gloomy… Do you have a free weekend and the good weather is with you? Now is the ideal time to intervene! Take the opportunity to impregnate your vertical wooden cladding. Thanks to the use of high-quality resins, impregnation varnishes offer excellent resistance while providing an elegant and refined decoration. There are different types of wood impregnation varnishes depending on exposure to UV radiation and weather conditions. So follow our advice to choose the right impregnation varnish for your wood.

Before painting your exterior woodwork, make sure that the impregnation varnish will be applied to the desired surface. Impregnation varnish is only applied to vertical surfaces such as gates, doors, shutters, beams, windows, etc. Do not apply impregnation varnish to a horizontal surface (e.g. wooden table, verandas, etc.). Impregnation varnish is applied to vertical surfaces and is therefore not very resistant to scratches and abrasions due to repeated use. We advise you to apply floor varnish to interior wooden floors and floor impregnation – Saturateur/Decking Oil to your exterior veranda.

Application tips

Sand lightly between coats (grit 120 sandpaper) to remove minor roughness in the wood and achieve a beautiful appearance.

Slightly round off (grit 80 sandpaper) sharp corners and edges of exterior woodwork to facilitate the application of the impregnation varnish and ensure better protection.

On soft woods (very porous) subject to high exposure, a final coat of colorless impregnation varnish will ensure a noticeable and more durable finish. In renovation, colorless also helps to protect the wood without darkening it.

Recommendation: for exteriors, colorless finishes should be used in combination with one or two coats of colored impregnation varnishes.

If the wood does not look healthy (larvae traces or holes from wood-eating insects), you must treat them beforehand with a suitable wood treatment product such as  Timpest Aqua Antitarlo (or a non-greasy treatment product), which will deeply impregnate and protect the wood. Let it dry for 48 hours before applying the impregnation varnish.

The impregnation varnish does not peel off, but over time the protective film degrades. Sand lightly and dust off. Then apply two new coats.

Precautions must be taken before applying to teak, iroko (exotic wood) etc.. Teak wood (and exotic wood in general) exhibits an accumulation of oily wood tannins that significantly reduce the adhesion of finishes. It is recommended to degrease the surface of the wood with acetone before applying the impregnation varnish of your choice.

The durability on lightly impregnated hardwoods such as Oak, Red Cedar, Iroko etc. is limited and reduced, as well as in the case of surfaces facing South or West.
