webercem mortar

Preblended, single-component, polymer-modified, cementitious mortar needing only mixing with water to produce a high quality surface levelling mortar and pore filler for most concrete surfaces.


  • Patch repairs to concrete floors.
  • Thin bonded vertical repairs to concrete.


  • Resistant to water penetration.
  • Excellent adhesion.
  • Faster strength development than ordinary sand-cement mortar.


For deep repairs in excess of 100 mm, other products available, consult Weber for exact details. Weber.cem mortar has greater chemical resistance to mild acid attack than normal sand/cement mixes, but in situations liable to chemical spillage weber.tec resin-based systems are more suitable.


Good curing is essential. Immediately after the finishing operation, apply Weber.tec ritecure byspray. Do not use Weber.tec ritecure between layers or where a finishing coat is to be applied, but spray with webercote primer and cover with close contact polythene sheet.

This product has been formulated to comply with the requirements of BS EN 1504-3.
