Osmo offers a natural and environmentally friendly alternative to wood finishing. The products are based on rapidly renewable, natural vegetable oils that penetrate deeply into the wood, keeping it elastic and healthy, whilst preventing it from drying and becoming brittle. The wood is allowed to breathe which means it is naturally protected, moisture can evaporate whilst the surface is very water resistant, water tightly beads on the surface which can be simply wiped off – and for exterior wood the rain will evaporate naturally, meaning little or no maintenance is required.
