Wood preservative Drewnochron impregnant extra film-forming oak 4.5 L

Drewnochron impregnant extra film-forming oak 4.5 L is a wood preservative and protective coating supplied in a 4.5-litre container. Formulated for both exterior and interior wooden surfaces, this film-forming impregnant penetrates the wood, creates a protective layer that increases water resistance and reduces UV damage, while enhancing and highlighting the natural wood grain with an oak shade. The product is intended for use on elements such as doors, windows, fences, garden furniture and cladding and can be applied by brush, roller or spray.

Advantages

This film-forming impregnant combines penetration and surface coating to protect wood from moisture and sunlight. Its formulation increases resistance to weathering and helps maintain the appearance of the wood grain in an oak tone. The product is suitable for various application methods — brush, roller or spray — which provides flexibility for different project scales. The 4.5 L volume is intended to cover medium to large surfaces or multiple smaller elements.

How to use

Ensure the wood surface is clean, dry and free from dust, grease and loose particles before application. Stir the impregnant thoroughly before use. Apply an even coat using a brush, roller or spray, following the wood fibres. For highly absorbent or weathered wood, apply a preliminary coat and allow sufficient penetration time before applying the final film-forming layer. Respect recommended drying times between coats and ensure good ventilation for interior applications.

Usage recommendations

Apply at recommended ambient and surface temperatures, avoiding rain or high humidity during exterior application. Test the oak tone on a small inconspicuous area or sample piece to verify the final appearance on the specific wood species. For best durability, recoat according to exposure and wear — inspect treated elements periodically and renew the coating when signs of wear, loss of water repellency, or fading appear.
