For bonding new cementitious materials to existing cementitious surfaces. For use on horizontal surfaces and on vertical surfaces where mortar on concrete can be supported by formwork.
ADVANTAGES
- Bonding fresh concrete to cured concrete and other surfaces.
- Bonding construction materials to dry and damp concrete surfaces.
- High physical strengths.
- Ideal working time.
INSTRUCTION FOR USE
Surface Preparation
The surface must be thoroughly cleaned and prepared. Remove all loose particles, dirt, dust, laitance, and mould release agent, curing compounds, oils, grease, floor hardeners and any waterproofing materials for best results. Remove laitance, dirt and dust by mechanical scarification such as wire brushing, scrapping, scabling or grit blasting. Clean the dust by pressurized air or by washing with water. Oil and grease should be removed by degreasing with solvents like turpentine of thiners. Visible signs of mould growth should be removed and treated with a fungicidal solutions. New concrete must be cured completely.
