Jotun Demidekk Decking and Garden Stain is a water-based wood oil for outdoor use. It is a special product for treating outdoor wood and pressure impregnated woods that are used, for example, in the construction of patio decking, balcony floors, garden furniture and pergolas. The coating protects the wood against the penetration of water, delays the process of greying due to harmful UV rays and has preventive action against surface fungi and algal growth.

Tinted in special grey shades, Jotun Demidekk Decking and Garden Stain can also be used as a weathered-grey stain, to provide the appearance of natural, even greying of the wood surfaces right from the start. Depending on the environment in which it is used, Jotun Demidekk Decking and Garden Stain can have a long service life of up to 3 years.

Cleaning/preparation: Weathered wood fibres or old coatings must be removed right down to the healthy wood. Use Jotun Demidekk Terrassfix beforehand to clean and brighten up the dirty and grey wood wood surfaces.


Surfaces that are to be coated must be clean and dry. Depending on the temperature and air humidity, Jotun Demidekk Decking and Garden Stain is touch dry after 4 hours and can be walked on after 12 hours. Freshly impregnated wood should dry for 2-4 weeks, depending on the weather, before Jotun Demidekk Decking and Garden Stain is applied. Remove the salt crystals that are on the surface of the wood with a brass brush and then wash the surface thoroughly with clean water (e.g. with a pressure washer - ensure nozzle is not too close).


When wood is dry, apply Jotun Demidekk Decking and Garden Stain to the surface once, wet-on-wet, until it is saturated. Work on only 1-2 boards at a time, but treat them along the full length. Excess material must be wiped off with a soft, lint-free cloth or with the brush. No film must be allowed to form.
