Mapei Mapecoat TNS Primer EPW

Application

Mapecoat TNS Primer EPW is used in combination with products from the Mapecoat TNS range. When used on Dutch asphalt, this primer is necessary, as the TNS system will not adhere sufficiently otherwise.

Examples of applications:

• Adhesion promoter for absorbent, porous cement-bound substrates
• Adhesion improver for existing sports and playing fields
• Adhesion improver for elastic Mapecomfort mats
• Primer for Mapecoat TNS products.

Also suitable as a primer for PU Sealer 750, PU 700 SL, PU 800 SL FR and PU 200 Finish.

Mapecoat TNS Primer EPW is a beige, two-component epoxy primer in aqueous dispersion developed by MAPEI.

After proper preparation and dilution as directed, apply in coats of 60-100 μm by roller, spray or airless system.

Important

• Do not dilute with solvents
• Do not apply to brittle or unstable substrates
• Do not apply at temperatures below +8°C or above +35°C

Apply

1. Substrate preparation

The substrate must be stable and load-bearing. Remove loose particles, cement residue, dust, paint, oil, release agents and other contaminants. Clean oil or grease contamination with water and 10% baking soda or a suitable detergent, followed by thorough rinsing. For deep contamination, remove the affected concrete and restore it with Mapgrout.

2. Product preparation

Add component A to component B and mix with a slowly running drill with stirring spindle until a homogeneous mixture is formed. Then dilute with water at a ratio of 1:0.5 and mix for another three minutes.

3. Applying

Apply one even coat with a roller with medium or long bristles, or with a sprayer. Wait 5-6 hours before applying the next coat of the system.

Consumption

100-200 g/m², depending on substrate suction and dilution.
