Marmox Multiboard

Made of extruded polystyrene that is covered with close woven fibreglass mesh embedded in a cement polymer mortar, Marmox Multiboard is a lightweight tile backer board that can be used to create a waterproof core, or to provide insulation either with underfloor heating or by dry lining exterior walls. They provide an even, smooth surface for tiles to be laid on and are strong enough to support even the heaviest of tiles and grout.

Uses for Marmox Multiboard

  • As a base for tiling - the basic function of a tile backer board is to provide a smooth, even surface for tiling on. Marmox Multiboards are specially designed to be able to hold the weight of even the heaviest of tiles and grout, and can hold 60kg/mē.
  • Insulation under underfloor heating - placing the boards below underfloor heating helps to reflect the heat upwards and minimise heat loss.
  • Dry lining insulation - the insulating properties of the boards make them ideal for dry lining exterior walls.
  • Waterproofing - the waterproof core of Marmox Multiboard makes it ideal for use in wet rooms and bathrooms on floors and walls to provide a waterproof layer prior to tiling. The joints between the boards will need to be waterproofed with Marmox waterproofing tape.

Waterproofing Wet Room Walls With Marmox Multiboard

Plasterboard walls or plywood walls are not suitable for tiling in wet areas and should be removed and replaced with Marmox tile backer boards (excluding 6mm). See fixing instructions below.

Plaster walls are not suitable for tiling in wet areas. The plaster should either be removed and Marmox boards installed, or Marmox boards should be mechanically fixed through the plaster surface into the studwork or brick/block surface behind. See fixing instructions below.

Fixing Instructions For Marmox Multiboard

Fixing to studwork partition walls - secure 10mm or 12.5mm thick Marmox tile backer boards. Each board should be fixed with fifteen 1.5" screws and tile backer board washers. All board edges should be supported. Each board should be butted together with DOW silicone sealant and the joints taped with Marmox self adhesive reinforcing tape roll, topped with a thin coat of a flexible fast-set cement-based adhesive. The boards should be fitted closely around any extruding pipe work, shower fittings or gaps and filled with DOW silicone sealant. If the gaps are larger than 1.5mm, use BAL WP1 waterproofing kit instead.

Fixing to brick or blockwork walls - secure 10mm or 12.5mm thick Marmox tile backer boards using one of the two methods below:

  1. If the walls are flat and true, the boards can be fixed using a flexible fast-set cement-based adhesive. After the boards have been fixed in position, drill nine 10mm holes through the board and hammer in the Marmox 60mm spankers.
  2. Fix the boards using the dry lining method. Each board should be fixed with fifteen 1.5" screws and tile backer board washers. All board edges should be supported. Each board should be butted together with DOW silicone sealant and the joints taped with Marmox self adhesive waterproofing tape roll, topped with a thin coat of a flexible fast-set cement-based adhesive. The boards should be fitted closely around any extruding pipe work, shower fittings or gaps and filled with DOW silicone sealant. If the gaps are larger than 1.5mm, use BAL WP1 waterproofing Kit instead.

Fixing to plaster walls - secure 10mm or 12.5mm thick Marmox tile backer boards using a ready mixed wall tile adhesive, suitable for use on plaster. After the boards have been fixed in position, drill nine 10mm holes through the board and hammer in the Marmox 60mm spankers. Fix the boards using the dry lining method. Each board should be fixed with fifteen 1.5" screws and tile backer board washers. Each board should be butted together with DOW silicone sealant and the joints taped with Marmox self adhesive reinforcing tape roll, topped with a thin coat of a flexible fast-set cement-based adhesive. The boards should be fitted closely around any extruding pipe work, shower fittings or gaps and filled with DOW silicone sealant. If the gaps are larger than 1.5mm, use BAL WP1 waterproofing Kit instead.

Fixing to floors - Marmox Tile Backer and Insulation Boards are fully waterproof and have the added advantage as acting as an insulation layer under an underfloor heating system, significantly improving the efficiency of heat output. The boards should be fixed to the wet room sub floor with a flexible fast-set cement-based adhesive (if fixing to a wooden floor, should also be fixed with fifteen 1" screws and tile backer board washers). Marmox boards should be butted together with DOW silicone sealant in all the joints. Marmox self adhesive waterproofing tape roll should then be fixed over the joints between the Marmox boards and the shower tray and between the wall and floor surfaces. Internal and external corners should be waterproofed with Marmox waterproofing corners and fixed with a flexible fast-set cement-based adhesive.

Marmox Showerlay Tray and Drain

The Marmox showerlay tray is a preformed shower tray that has a fully waterproof closed cell polystyrene core with a cement scrim to back and front for strength. The wet room shower tray can be placed directly onto the existing wooden or concrete floors, however if the desired shower area is to be level access, the shower tray must be cut into the floor, reinforced and fully supported beneath.

The Marmox showerlay can easily be cut to fit the shower area or to produce an irregular or circular shower base. The showerlay is compatible with Dallmer shower drains, which at 87mm deep are easily accommodated under most floors. It is recommended to encase the drain using polyurethane foam to provide additional support.

The Marmox Showerlay is sufficiently robust to be surfaced with mosaic tiles (minimum of 50mm) and is ready to receive a tiled finish of the customer's choice.

Marmox Showerlay Sizes

Marmox Drains

The Dallmer shower drain with removable trap is compatible with the Marmox showerlay. It is available in both a vertical outlet and a horizontal outlet design. The horizontal drain has a slim profile, at just 83mm depth below the shower tray, to maximise space usage and accommodate buildings with a reduced floor depth level. The Dallmer drain has an exceptional discharge rate of 0.5 litres per second. Each drain is supplied with a 137mm stainless steel drain plate and DN50 connector with adaptor.

Marmox Curved Board

Marmox curved tile backer board has all of the benefits of the regular Multiboard but its curved shape makes it great to use for irregular shaped areas.

Marmox Bath Panel

The Marmox bath panel is ideal for use if you want to tile the side of your bath to tie it in with the rest of the bathroom.

Marmox Ancillaries

Marmox also produce a whole host of ancillary products including metal washers, internal and external corners and waterproofing tape.
