webercem fairing coat

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.


  • Levelling new and old concrete surfaces, infilling surface imperfections.
  • Making good concrete blow holes, filling small holes.
  • Making good frost damaged and scoured concrete surfaces.
  • Levelling of patched concrete repairs.


  • Dual action: Can be used as a pore filler and a levelling mortar.
  • Easy to apply: does not slump or slip.
  • Good adhesion to prepared concrete, compatible with typical concretes.
  • Good carbonation resistance: Contributes to the properties of the webercem concrete repair system.
  • Allows water vapour to escape – does not blister.


Not intended as a final finish; normally, an anti-carbonation coating from the webercote range can be subsequently applied. Do not use solvent or silane-based coatings.

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