Wet Area Tips

  • For protection against steam and moisture damage use GIB Aqualine®. It also offers added fire protection with a superior fire rating to GIB® Standard plasterboard.

  • If you are renovating consider removing the old linings. Check the condition of existing plumbing and framing.

  • Tiled surfaces are not totally impervious to moisture so tiled 'splash' areas should first be coated with a waterproof membrane (a special coating that helps seal the plasterboard surface) for added protection.

  • Make your bathroom look bigger by using light wall colours, adding more lights and mirrors; and de-cluttering the room (example: replace floor cabinets with wall cabinets).

  • In kitchen areas include a glass or tile splash-back and range hood to help minimise moisture build up.
