Class R2 Fairing Coat (EN1504-3)


Monolevel FC is an engineering quality fairing coat for filling minor blow holes and defects, and for repairing surface imperfections. Monolevel FC can be used in thin screed applications to level both vertical and horizontal concrete surfaces and to reinstate cover while providing a fair faced anti-carbonation finish.

Monolevel FC is a single component, thixotropic, polymer modified, cementitious mortar with high adhesive properties, allowing it to be used as a thin screed, as well as a filler for filling minor voids and defects to provide a fair faced finish. It incorporates the most advanced microsilica, fibre and polymer technology, curing to provide enhanced freeze/thaw resistance and protection from the ingress of water, acid gases and chlorides. The product is supplied as a single component system requiring only the addition of clean water.


  • Incorporates the latest proven cement chemistry, microsilica, fibre and styrene acrylic copolymer technology
  • Pre-packaged material requiring mixing with clean water on-site to give an adhesive mortar which can be rapidly applied in vertical and horizontal situations by brush, bag-rubbing, trowel or spray techniques
  • High bond strength exceeds tensile strength of concrete, thus ensuring monolithic performance of the repair
  • Dense matrix provides excellent protection from ingress of acid gases, moisture and chlorides
  • Non-toxic when cured
  • Economic mortar requiring no substrate or inter-layer priming. Part bags can be mixed. Suitable for feather edging
  • Suitable as an exposed external finish without further protection or coating
  • Easily overcoated with specialist membranes to provide further protection and aesthetic quality.


CE marked in accordance with BS EN 1504 Part 3. Fully complies with the Highways Agency Standard BD 27/86 for the repair of Highway Structures. Compliant with LU Standard 1-085 ‘Fire Safety Performance of Materials’.
