Sika - SikaRepair -30F jednosložková vyrovnávací malta

One-component, leveling polymer-cement mortar (PCC / SPCC), containing microsilica.

Features

• material supplied ready for use, requires mixing only with water
• the possibility of obtaining a different, smooth surface
• class R3 in accordance with PN-EN 1504-3
• resistance to chemical aggression
• ease of preparation and application
• good mechanical properties, tightness

Application

• minor structural and non-structural repairs by manual method and for making putty on concrete surfaces exposed to increased environmental aggression, e.g. in general construction; hydrotechnical construction: sewage treatment plants, dams, dams, reservoirs, canals, according to industry: pavements, underground workings, shafts
• material ideal for leveling the surface before applying protective coatings
• repair work (principle 3, methods 3.1 and 3.2 of PN-EN 1504-9); repair of peeled or damaged concrete in buildings and other reinforced concrete structures (manual application of repair mortar, application of a mortar layer)
• preservation or restoration of passivity (principle 7, method 7.1 and 7.2 of the PN-EN 1504-9 standard); increasing the thickness of the reinforcement cover and replacing damaged or carbonated concrete
• leveling concrete surfaces in layers with a thickness of 1.5 to 4.0 mm in the Sika Repair concrete repair system
