1. Preparing the substrate
All surfaces to be treated must be firm and compact. Remove all loose or peeling parts, cement residue, dust, paint, oil, release agent and foreign matter from the substrate. Oil- and grease-soaked concrete surfaces should be thoroughly cleaned with a solution of water and 10% soda or with a cleaning agent, after which they should be rinsed several times with a generous amount of clean water. If the oil or grease has penetrated deep into the substrate, the affected concrete pieces must be broken away. The substrate must then be repaired with a special mortar from the Mapegrout range.
2. Preparing the product
Add component A to component B container and mix the two components using a slow speed rotary drill with stirring spindle until an even mixture is obtained. Dilute this mixture with water in a ratio of 1 : 0.5 and mix again for three minutes with the drill with a stirring spindle.
3. Applying the product
Apply a single, even coat of Mapecoat TNS Primer EPW with a roller with medium or long bristles or with a sprayer. Wait 5-6 hours before applying the next product of the coating system.
