MK-approved waterproofing membrane system (wet room)

Complete system: primer → membrane → adhesive → grout

Complete MK-approved (ETA-Danmark) or ETA/TGA-documented wet-room system. Liquid membrane is typically applied in ≥ 2 coats to a total thickness of ≥ 1 mm. The system is only used as one complete approved system — not by mixing components across approvals. Corners and transitions are secured with sealing tape; penetrations with sleeves. Guide price for a whole wet room (labour + materials): ~600–900 kr./m² (Badeværelsepriser.dk, accessed 2026-06-16). Source: the specific system's MK approval (ETA-Danmark); BR18 § 339; SBi 252.
