- Fixed to walls at 250 mm centres by drilling through membrane studs and inserting plaster plugs. Lap sheets 90 mm and seal using tape.
- Suitable for ventilated application on walls above DPC level: Leave 20 mm gap to bottom of wall membrane and 10 mm gap to top. Insert profile strips into applied finishes or offset skirtings and covings.
- Suitable for applied coatings on walls: Use lightweight gypsum plasters or 1:1:6 cement:sand:lime render. 8 mm first coat to fill studs. 7 mm second coat. 3 mm skim coat. (Plaster or render specified elsewhere).
- Suitable for applied dry linings on walls.
- On floors, loose lay with compression studs downwards. Butt joint and seal using Overtape. Seal wall/ floor junction using Corner detail trim.
