Ceresit CT80 Universal Adhesive for Mineral Wool, Polystyrene and Phenolic EWI Boards

Coverage: 5m3
Weight: 25kg

Ceresit CT80 is an universal adhesive mortar for fastening mineral wool, polystyrene and phenolic EWI boards and also as a thin layer of base coat render reinforced with fibreglass mesh on the insulation boards in Insulated Renders Systems. Ceresit CT80 has very good adhesion to load bearing substrates, such as surfaces of walls, plasters, mosaics and concrete. 

CHARACTERISTICS

  • Universal,
  • Elasticised,
  • Breathable,
  • Durable,
  • Excellent adhesion,
  • Resistant to adverse weather conditions,
  • Can be machine applied.

APPLICATION

  • For fixing EPS, phenolic boards and mineral wool slabs to substrates,
  • Fixing a protective reinforced layer for thermal insulation,
  • In new builds and for thermal-renovation of existing buildings.

INSTALLATION

  • Before starting work, check the adhesion of existing plasters and coatings. Dull sounding plasters must be removed. Defects and unevenness of the substrate should be levelled.
  • The surface should be free from fats, bitumen, dust and other substances that reduce adhesion.
  • Places with moss and algae should be cleaned and then saturated with a fungicide solution.
  • Mix using a mechanical mixer to a homogeneous mass without lumps, wait 5 minutes and stir again.
  • Apply 3-4 cm band mortar with a trowel along the edges of the slab and a few blobs ~ 8 cm within the slab.
  • Push the slab on to the wall and press it firmly. Properly applied mortar should cover min. 40% of its area, after pressing.
  • Apply the mortar using a toothed trowel.
  • The boards should be fixed tightly to one another, in one plane, with a zigzag vertical jointing.
  • After CT80 mortar is bound, after about 3 days, the mineral wool slabs should be additionally fastened with mechanical fasteners.

Fixing a mesh reinforced layer

  • Apply a primer on the mineral wool slabs.
  • After the primer layer has dried - approx. 24 hours, apply Ceresit CT80  prepared mortar with a notched trowel on the surface of mineral wool boards.
  • Apply a fibreglass mesh to the fresh mortar, then smooth the surface evenly so that the grid is no longer visible.
