With a permanent, waterproof coating on both sides, the flooring is BBA-certified for exposure to construction work and the elements for up to 60 days when fixed with Caberfix D4 adhesive. After work is complete, the floor can be wiped clean so that it is ready for finishings such as carpet and laminate.
