  • Metal elements, such as reinforcement, must be free of rust, dust, mortar residues or other materials that may impede adhesion or contribute to corrosion.
  • Absorbent substrates must be wetted to saturation without puddling.
  • The substrates must be clean and sound, free of grease, paint or other substances that would prevent proper adhesion.
  • Very smooth substrates shall be mechanically treated to ensure proper adhesion of the repair mortar.
  • A suitable adhesion primer shall be used on low-porosity surfaces.

Instruction for Use

Surface Preparation / Priming Careful surface preparation is essential for optimum finish and durability. The surface needs to be clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the coating. New concrete structures need to dry for at least 28 days. Old coatings, dirt, fats, oils, organic substances and dust need to be removed by a grinding machine. Possible surface irregularities need to be smoothened. Any loose surface pieces and grinding dust need to be thoroughly removed. Do not wash surface with water! Do not apply the REVESTIDAN FINISH when the ambient temperature is below +5ºC during the application and 4 hours afterwards, on surfaces with Temperature below +5ºC, on frozen surfaces, during rain or mist, and on surfaces with ascending humidity. Low temperatures retard cure while high temperature speed up curing. REVESTIDAN FINISH is slippery when wet. In order to avoid slipperiness during wet days, sprinkle suitable aggregates onto the still wet coating to create an anti-slip surface. Waterproofing membranerStir REVESTIDAN FINISH slowly and well with wooden staff before using. Do not use a mechanical drill. Apply REVESTIDAN FINISH onto the prepared and/or primed surface by roller or brush (in details use a roller 10 cm width), until all surface is covered. If necessary apply a second layer.


  • Do not apply when there is a risk of frost, rain, strong wind or direct sunlight.
  • Do not apply below 5°C or above 30°C.
  • Do not apply on plaster supports.
  • Do not apply to plastic, wood, rubber, etc. surfaces.
  • Protect the cool surface from direct sun, rain and especially draughts.

Handling, storage and preservation

  • It is packaged in 25 kg multi-leaf paper bags with damp-proof sheets that allow it to be stored for 12 months in its original sealed packaging, safe from dampness.

Cleaning of Work Tools

Tools are easily cleaned with water before the adhesive has hardened.
