Product overview

Where is it used?

  • Multipor FIX X710 is applied to the back of the Multipor boards to bond them to the wall surface.
  • It can be used internally or externally on walls, plinth areas and ceilings.
  • As a plaster coat, it can also be used internally or externally and reinforced with a fibreglass mesh, such as Baumit StarTex mesh.

How is it used?

  • The back of the boards should be fully coated with the FIX X710 and combed with a 10-12mm knotched trowel, to ensure an even thickness. All ridges must be full to get an even thickness coat.
  • The boards are then applied to the wall around 5mm away from adjacent boards.
  • Once in position, slide the board 5mm up to the adjacent board in a direction perpendicular to the direction of combing. This ensures that you create a fully filled layer behind the boards, with no voids present.
  • As a plaster layer, apply to the surface of the Multipor boards and comb with a 10-12mm knotched trowel to ensure an even thickness.
  • Whilst wet, lay in a layer of the Baumit StarTex mesh and trowel so that the mesh is covered by around 1mm of the FIX X710 plaster.
  • Leave to dry for 4-5 days before applying the Baumit RK 70N lime plaster finish coat or Baumit Klima Glatte lime finish coat for a finer finish.

How much will you need?

  • Each 20kg bag will cover up to 5.5m2 at 5mm.
  • You will need to use a 5mm coat as the adhesive layer and also as the base coat plaster layer.
