Preparation of Substrate
Concrete surface must be sound, clean and dry. Surface must be clean off dust, dirt, rust, oil and all contaminants. If there is a water leakage, it must be drained or properly plugged. Concrete surfaces must be saturated with water before application. Immediately before pouring, surface should be wetted, then remove all excess or standing water from within any formwork.
25 kg REPAMERK 301 is poured into maximum 4 liters of water and mix for 3-4 minutes under low speed mixer until having a homogenous consistency. Let the mortar have rest for 4 minutes and re-mix for 30 seconds. Prepared mortar should be applied within 30 minutes in 20°C. REPAMERK 301 is applied on the surface by using a steel trowel or spray gun. Application thickness should be between 10-40 mm. If needed second coat should be applied after 24 hours in same way. 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 19,20 kg/m² is required.
