Water-soluble epoxy primer suitable for the Neoproof® Polyurea waterproofing system.

Uses

Acqua® Primer NP is a primer suitable for the preparation of surfaces to be coated with Neoproof® Polyurea waterproofing systems. It creates chemical adhesion with polyurea, contributing to the long-term durability of the waterproofing.

Properties

✓Two-component water epoxy primer with very strong adhesion.
✓Suitable for surfaces made of concrete, polyurethane thermal insulation foam, bituminous membranes with slate, to be coated with Neoproof® Polyurea waterproofing systems.
✓Compliant with Directive 2004/42/EC on the use of organic solvents in decorative paints and varnishes.

Special Recommendations

The surface moisture should not exceed 6%. • It should not be applied when wet weather and low temperatures below 12°C are expected before the film has fully dried. • The application of Neoproof® Polyurea system materials should be done 24 hours after the primer application to achieve chemical adhesion between the primer and polyurea. If this cannot be done, the primer surface should be roughened before applying the waterproofing material. • Defects (holes, cracks, etc.) on both new and old surfaces should be filled with Epoxol® epoxy putty or Neotex PU Joint polyurethane sealant, which should dry adequately for 2-3 days before applying Neoproof® Polyurea.

Tool Cleaning

Immediately after use with water.

Stain Removal

While still wet with water. If hardened, remove mechanically.

Storage Time

3 years (5-35°C) in sealed containers.
