Application

Suitable for use insulating, waterproofing and fixing ceramic and stone tiling and brick slips to external walls.

Description

Waterproof, thermally insulating tile backer board for external use providing an effective decoupling layer between the tiled surface and the substructure. This helps to prevent tiles and grout from cracking due to horizontal movement in the floor and allows heavy weights to be safely and securely fixed to walls.


An internal board is available, specified separately.


Features and benefits:

  • Lightweight.
  • Dimensionally and structurally stable in all weather conditions.
  • Resistant to freeze-thaw damage.
  • Impermeable to water, and acts as a moisture barrier.
  • Thermal insulation is unaffected by various temperatures.
  • The cementitious surface is resistant to heat and chemicals.
  • Can easily be cut in straight lines.
  • Provides enhanced tile adhesion.
  • Load bearing capacity exceeds 100 kg/m².
  • Boards can be aligned horizontally or vertically.
  • Does not contain any hazardous substances.
  • Manufactured in accordance with ISO 9001 Quality Management Systems and BS EN 5385-2, and CE marked to EN 13164.


Boards should be stored flat and covered with scrim/ reinforcing tape. For fitting instructions onto different types of substrate, consult manufacturer's literature.
