Cement based polymer modified base coat render for ETICS webertherm base is a pre-bagged dry blend of cement, aggregates, polymer, and additives. It provides an excellent reinforcing coat for embedding glass fiber mesh in facade insulation system (ETICS). It is elastic, crack-proof and resistant to mechanical stress. webertherm base has an outstanding bonding effect and is water resistant.

To know before applying

  • Surface must be clean and free from greasy matters or dust
  • Use a stainless notched trowel to apply the mortar to the surface of the EPS insulation board to a uniform thickness of appr. 2 to 3 mm 
  • Immediately, lay in the meshcloth . Once the initial coat has started to ‘take-up’, apply a second layer of adhesive mortar to produce a sandwich approximately 6 mm thick totally encapsulating the meshcloth

Features and benefits

  • Polymer modified for high bond strength.
  • Factory batched for consistency
  • Easy to spread

Constraints

  • The meshcloth must lie within the outer one-third of the webertherm base.
  • At joints, individual meshes should overlap each other by 10 to 15 cm.
  • At corners special reinforcing corner angle glass fiber mesh is used.
  • In order to protect against the formation of cracks, in areas where larger local stresses are to be expected, i.e. in the vicinity of the corners of door, window and other openings, strips of mesh (app.20 x 40 cm) should be placed diagonally across the corners.
  • In case a thick mineral finish is required, lightly comb scratch the webertherm base to achieve a good mechanical key.
