OWATROL DEKS OLJE D1 is a low-viscosity, transparent oil that is ideal for saturating wood, especially hardwoods and tropical woods. Due to its enormous penetrating capacity, it penetrates deep into the wood and displaces any moisture and air present. On the one hand, complete saturation prevents solid wood from working so that it no longer swells. On the other hand, the oil provides preventative protection against fungal and mold infestation. In the case of porous wood, treatment with D1 facilitates subsequent painting, as saturated wood absorbs less varnish or paint.OWATROL D1 can be applied to new, untreated wood or to wood that has already been weathered (with appropriate preparation). As a sole preservative, a permanently elastic, breathable, silky matt surface is achieved (e.g. for non-slip decks). OWATROL DEKS OLJE D2 is recommended as a film-forming further treatment. OWATROL D1 can also be painted over with 1-component primers and alkyd paints.Application: The product is applied in several coats until the wood is saturated. Then wait 15-20 minutes to allow the oil to soak in. Do not allow the oil to dry between coats, but work wet on wet. After the last coat, the surface should be wiped with a clean cloth after the waiting time to avoid the formation of a film.Important: To saturate wood in underwater areas, ensure that the wood is coated with a waterproof blocking primer (silver primer, CR primer). A recoating interval of at least one week (at 20°C) should be maintained between OWATROL D1 and primer, and correspondingly longer at cooler temperatures. It is also important to ensure that after the last coat of OWATROL&nbspTechnical DataSubstrate: All wood types, including dense and oily hardwoods (e.g. teak, mahogany),Application area: interior and exteriorSurface preparation:Remove old coatings completelySand wood dry with 120 grit and clean (e.g. with denatured alcohol)For decks: sand with 40 grit, brush in grain direction using brass brush for slip resistanceTopcoat: Above water: OWATROL DEKS OLJE D2, 1component-PUR varnishes, alkyd-based coatings (test first); Below water: chlorinated rubber primer + antifoulingCoverage: 1–4 m²/l (initial saturation), 8–12 m²/l (maintenance)Thinner: None Application method: Flat brush, mohair roller, spray deviceDrying times at 20 °C: Fully cured after 3 daysFurther information on applying this product can be found in the technical data sheet under "Downloads".
