Sadolin Extra Durable Clearcoat

Sadolin Extra Durable Clearcoat is a premium-quality, solvent-based clear woodstain specifically developed as a durable finishing treatment for exterior joinery. Forming a flexible, microporous film, it is designed to accommodate the natural movement of timber, helping to prevent common coating failures such as cracking, blistering, or peeling. Its transparent satin or gloss finish enhances the natural grain and colour of the wood, offering a refined appearance while delivering robust protection against environmental elements.

Ideal for use on exterior timber such as windows, doors, conservatories, cladding, and garden buildings (excluding decking), Sadolin Extra Durable Clearcoat acts as a breathable yet weather-resistant barrier. It contains advanced UV filters to combat the damaging effects of sunlight, helping to reduce greying and surface degradation, while also repelling rain and moisture. Though clear in appearance, it behaves much like a lightly pigmented stain in terms of performance, providing excellent adhesion and long-term durability.

This clearcoat is especially effective when used as a finishing layer over base coats such as Sadolin Classic Wood Protection or Sadolin Extra Durable Woodstain, sealing in colour and further extending the life of the woodcare system. It is the ideal solution for those seeking a natural-looking, low-maintenance finish that doesn’t compromise on performance or protection.
