Wood preservative Drewnochron impregnant extra film-forming walnut dark 9L

Drewnochron impregnant extra film-forming walnut dark 9L is a pigmented wood preservative formulated for both exterior and interior wooden surfaces. Supplied in a 9-litre container, the product creates a continuous film that penetrates and coats wood fibres while providing a decorative dark walnut tint. It is intended to protect wooden fences, garden furniture, cladding and joinery from moisture and weathering, while evening out appearance and enhancing surface durability.

How to use

Prepare the wood by cleaning it from dust, dirt, old flaking coatings and any fungal growth; sand smooth and remove sanding dust. Apply the impregnant at recommended ambient and substrate temperatures, stirring the container before use to ensure uniform pigment dispersion. Apply evenly using a brush, roller or low-pressure spray, maintaining wet edges to avoid lap marks. Allow adequate drying time between coats as indicated by product data, and apply additional coats when greater coverage or deeper colour is required. On previously coated surfaces perform an adhesion test and remove incompatible or poorly adhering layers before re-coating.

Usage recommendations

For best results, apply the impregnant on dry, well-prepared wood and avoid application in direct rain or high humidity. Use at least two coats for exterior exposure and follow ventilation and drying time guidance. Store the product in a cool, frost-free place and protect from direct sunlight prior to use.
