Key features

• Class R4 of EN 1504-3
• Sulphate resistant
• Hand or machine application
• Up to 50 mm in 1 layer on vertical surface, 2 layers overhead
• Very low shrinkage
• No bonding primer required even when manually applied
• Low permeability
• A1 fire rating
• Substrate must be pre-wetted for a minimum of 2 hours to saturated surface dry (dark matt appearance)
• Bonding primer generally not required on well prepared, roughened or sprayed substrates
• otherwise Sika MonoTop-1010 IN or SikaTop Armatec-110 EpoCem
• Can be applied manually or by wet spray

Applications

• Repair of reinforced concrete in buildings, civil engineering structures, dams, marine structures
• Sewage and waste water treatment plants
• Structural strengthening (EN 1504-9 Principle 4)
• Restoring passivity / increasing cover (Principle 7)
• Interior or exterior
• Concrete repair (manual or wet-spray application)
