Mapei Mapecoat TNS Primer EPW

Application

Mapecoat TNS Primer EPW is recommended for use with Mapecoat TNS series products. Also use this primer on Dutch asphalt, as the adhesion of the TNS system directly on Dutch asphalt gives lesser adhesion.

Application examples

• Adhesion enhancer for absorbent, porous cement substrates.
• Adhesion enhancer for existing playing fields.
• Adhesion enhancer for elastic Mapecomfort mats.
• Primer for products in the Mapecoat TNS range.

Primer for PU Sealer 750, PU 700 SL, PU 800 SL FR and PU 200 Finish.

Apply

1. Substrate preparation.

All surfaces to be treated must be firm and compact. Remove all loose or flaking parts, cement slurry, dust, paint, oil, release agent and foreign matter from the substrate. Concrete surfaces smeared with oil and grease should be thoroughly cleaned with a solution of water and 10% soda or with a detergent, then rinsed several times with a generous amount of clean water. If the oil or grease has penetrated deep into the substrate, the affected pieces of concrete must be broken away. The substrate must then be repaired with a special mortar from the Mapegrout range.

2. Preparation of the product

Add component A to the container of component B and mix the two components using a slowly rotating drill with a 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 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.

Consumption

100-200 g/m2, depending on the absorbance of the diluted primer.
