REPAMERK 1 is cement based one component, polymer modified repair mortar for non-structural repairs on concrete structures.
Preparation of Substrate
Application surface must be dry, clean and clean off materials which prevent bonding, such as dust, oil, rust and remove loose pieces. If there is a water leakage it must be drained or properly plugged. Concrete surfaces must be saturated with water before application. Defects up to 4 cm depth should be repaired with REPAMERK 301.
25 kg REPAMERK 1 is mixed with 5,5 - 6,0 liters water under low speed mixer for 3-4 minutes until obtaining homogenous mixture. Mixture should be applied in 30 minutes at 20°C. REPAMERK 1 is applied with a trowel as 5-30 mm thickness. If required more smooth finish, water should be sprayed onto the mortar and the surface should be finished with using steel or wooden trowel. Application surface must be protected from the rain, wind,frost etc. during first 24-48 hours after finishing repair.
For 10 mm thickness approximately 15 kg/m² is required.
