It is a cement based, one component, polymer modified, corrosion protection coating and bonding agent mortar.
Preparation of Substrate
Concrete subsrates: Must be clean, sound and free from dust, oil, grease and other contaminats. Surfaces should be abraded with needle gun, mechanical wire brush etc. Surface laitance must be removed. The prepared substrate should be wetted with water until uniformly saturated, leaving any standing water.
Steel reinforcement: All surface must be clean, free from oil, grease, rust and other surface contaminants. Surface should be ready by sandblasting.
5,5 - 6 lt water is mixed with 25 kg REPAMERK 325. Powder is added into water and slowly stir with electrical stirred until getting homogenous mixture during 4 minutes. Let the mortar have rest for 4 minutes and re-mix for 30 seconds to apply with brush, roller or spray gun.
As Reinforcement Corrosion Protection: REPAMERK 325 is applied on steel surface approximately 1 mm thickness with brush or spray. After 4-5 hours later second layer is applied as the same thickness. The subsequent repair mortar should be applied after a similar period of time.
As Primer: REPAMERK 325 is applied on concrete surface approximately 1 mm thickness with brush,roll or spray. If surface is too absorbent, second layer should be applied after 3-4 hours later. The subsequent repair mortar should be applied while REPAMERK 325 is still wet, nearly 30 minutes later.
1,55 kg of dry powder is used for 1 liter mixture.
As primer; 1,50 - 2,0 kg/m² dry powder.
