German Engineering. Natural Ingredients. Professional Results.

Osmo is Germany's leading manufacturer of natural oil and wax-based wood finishes — trusted by flooring specialists, joiners, and finishing contractors across the UK for over 40 years. Unlike film-forming varnishes and lacquers that sit on the surface and eventually crack or peel, Osmo products penetrate deep into the wood grain, nourishing the timber from within and creating a finish that is breathable, durable, and genuinely long-lasting.

At Hart Wholesale we stock the full Osmo range at trade prices, from Polyx-Oil hardwax oils for interior floors to Decking Oils for exterior timber, Country Colours for cladding and joinery, and the complete range of maintenance and application accessories.
