The mountain marine varnish ''le robuste'' is a high quality eco-label varnish, completely colourless with very effective anti UV agents. It is a product belonging to the film-forming category, which therefore forms a film on the surface, unlike oils and saturators, which are in the non-film-forming category. This very robust varnish, hence its name, is particularly popular for protecting woodwork against weathering and UV radiation and for boats. In addition, where a tint is required for UV protection, the robust marine mountain varnish provides excellent protection even with its colourless finish. Its polyurethane binder ensures a good performance over time, and a quality protection for your wood.
