DREVOZAHIST IMPREGNAT Antiseptic Wood Preservative, Oak, 0.7 kg

DREVOZAHYST IMPREGNAT by POLIFARB is an alkyd impregnation for the decorative and protective treatment of timber and wood-based surfaces, indoors and out.

An impregnation, not a coating

The key difference from lazures and varnishes: it soaks deep into the timber and polymerises inside the fibres rather than forming a film on top. A film eventually peels, and what it was meant to prevent starts underneath; an impregnation has nothing to peel from. It is not a finish coat, though: once dry, the surface is protected with pentaphthalic varnish, 1–2 coats for items used indoors and 2–3 coats for items exposed to weather. Indoor floors are treated only in combination with varnishes.

Three threats

The impregnation protects timber against fungi, insects and mould, and against rain and temperature swings.

The colour of fine timbers

Eight options: clear, pine, teak, oak, mahogany, walnut, wenge and classic rosewood. The pigments are UV-stable and the colour is durable.

It still breathes

The treatment does not block vapour permeability, so log walls, gazebos and cladding keep releasing moisture rather than storing it.

Where it is used

Timber facades, log houses, gazebos, fences, furniture, windows, doors, cladding, skirting, natural timber panels, plywood, OSB, MDF, chipboard and hardboard, and the outside of beehives.

Conditions

Stir thoroughly before use; thin with white spirit. No primer needed. Two or three coats, 80–100 g/m² per coat, the next coat after 8 hours. Apply with a soft brush, pad or sponge along the grain; do not spray. Air and substrate +5 to +30 °C, humidity no more than 60%. Clean tools with white spirit. The impregnation is flammable. 18-month shelf life, do not freeze. Packed in 0.7 kg.
