Antiseptic Valtti Color colorless 2.7 L, Tikkurila – wood preservative and primer

Tikkurila Antiseptic Valtti Color colorless 2.7 L is a transparent wood preservative and primer formulated for exterior timber protection. Designed to penetrate wooden substrates, it helps prevent decay, inhibit fungal growth and increase resistance to weathering while leaving a clear, non-pigmented finish. The product is intended as an initial treatment before applying decorative topcoats or as a protective maintenance layer for facades, fences, garden structures and other outdoor wooden elements.

Advantages

Its antiseptic properties reduce the risk of rot and fungal attack, and the primer function improves adhesion and durability of subsequent coatings. The composition is suitable for use on a variety of exterior woods and supports efficient surface preparation and maintenance operations.
