A repair mortar, mineral reinforced with the addition of plastic fibers. It is used for repairing and leveling concrete surfaces. The product is characterized by high chemical and mechanical resistance. Suitable for leveling the substrate under anti-corrosion coatings such as Koester NB 1, PSM, CMC.
Properties
- very high adhesion to both old and new mineral substrates
- reinforced with plastic yarns
- based on cement with increased resistance to sulphates
- high chemical and mechanical resistance
- high compressive strength
- perfect for preparing the substrate for anti-corrosion coatings made of Koester PSM or Koester Silikatm rtel on facilities such as sewage treatment plants, industrial chimneys, industrial facilities exposed to aggressive chemical substances
Application
- repair and reprofiling of concrete substrates
- filling the cavity in
- leveling the concrete surface
- repair of elements in structures exposed to chemically aggressive environments and mechanically loaded, e.g. in industrial and agricultural facilities, water and sewage management, industrial chimneys under gas flow conditions in aggressive
