MAPEPROOF SA PRIMER 10kg

Mapei Mapeproof SA Primer – Rapid-Drying Primer for Self-Adhesive Waterproofing Membranes

Mapei Mapeproof SA Primer is a one-component, solvent-based polychloroprene primer designed to prepare concrete surfaces before installing Mapei Mapeproof and Mapethene self-adhesive waterproofing membranes.

It helps improve adhesion between the prepared concrete substrate and the self-adhesive membrane, supporting a fully bonded waterproofing installation for underground structures, foundations and basement applications.

Ready to use straight from the container, Mapeproof SA Primer is applied by brush or roller. Once the primer has dried but remains tacky, the self-adhesive waterproofing membrane can be installed.

Surface Preparation

Correct concrete preparation is essential for achieving reliable membrane adhesion.

• Concrete must be sound, flat and clean.
• Remove cement laitance, loose and crumbling material.
• Remove dust, grease and form-release agents.
• Pressure wash the substrate where appropriate and allow all water to dry before priming.
• Repair gravel clusters, surface irregularities and damaged concrete before application.
• Treat exposed reinforcement with the appropriate Mapei anti-corrosion product.
• Repair gaps and damaged areas using a suitable Mapei structural repair mortar.
• Form suitable coves at internal corners and round off sharp edges before applying the waterproofing system.

Mixing and Application

Mapeproof SA Primer is supplied ready to use. Mix the contents of the container thoroughly to ensure the product is evenly blended before application.

• Ensure the concrete substrate has been correctly prepared and is dry.
• Apply one even coat using a suitable brush or roller.
• Allow the primer to dry while remaining slightly tacky.
• Install the compatible self-adhesive waterproofing membrane onto the prepared surface.

The membrane must be applied within the manufacturer's specified covering time. For Mapeproof SA, the maximum covering time is 24 hours.

Coverage

Typical consumption is approximately 200g/m², depending on the absorption rate of the concrete substrate.

As an indicative guide, one 10kg drum provides approximately 50m² of coverage. Actual consumption will vary according to surface condition and absorption.

Important Application Information

• Designed for concrete substrates before installing compatible self-adhesive membranes.
• Do not apply to wet concrete.
• Do not dilute with solvent.
• Ensure the primer is dry but still tacky before applying the self-adhesive membrane.
• Observe the maximum 24-hour covering time for Mapeproof SA.
• Clean application tools with a suitable solvent such as white spirit or nitro thinner.
• Once dry, the primer can only be removed mechanically.
• Use appropriate protective equipment and ensure adequate ventilation when handling this solvent-based product.
