Gripset GP Primer: A Technical Overview
Gripset GP Primer is a water-based acrylic primer designed to penetrate and seal porous substrates, providing a stable surface for the application of Gripset waterproofing membranes. By reducing surface porosity, it prevents rapid membrane absorption, promotes uniform curing, and improves long-term adhesion performance. Suitable for internal and external use, GP Primer is quick-drying, low VOC, and easy to apply with brush, roller, or spray.
Core Features & Specifications
- Seals porous surfaces to improve membrane adhesion.
- Reduces surface absorption and porosity for uniform finish.
- Water-based, low VOC formulation for safe indoor use.
- Fast-drying, allowing quicker membrane application.
- Compatible with Gripset waterproofing membranes.
- Easy application via brush, roller, or spray.
The Gripset GP Primer Advantage
- Ensures optimal bond strength between substrate and membrane.
- Suitable for a wide range of porous building materials.
- Dries quickly, reducing project downtime.
- Water-based for easier clean-up and safer handling.
Proactive Troubleshooting
Scenario: Applying membrane to an unprimed porous surface
Potential Outcome: Poor adhesion and uneven curing.
Adheseal Best Practice: Always prime with GP Primer to achieve consistent coverage and membrane performance.
Scenario: Applying GP Primer to a damp surface
Potential Outcome: Reduced penetration and adhesion.
Adheseal Best Practice: Ensure surface is dry before application for best results.
Applications in Practice: Trade Scenarios
For Waterproofers: Wet Area Preparation
The Professional's Challenge
Wet areas require a stable, sealed surface to prevent premature membrane failure.
The Adheseal Solution
GP Primer penetrates porous substrates, reducing absorption and creating an ideal surface for Gripset membranes.
Best Practice Note
Apply GP Primer evenly and allow to dry fully before membrane application.
For Builders: External Deck Preparation
The Professional's Challenge
External decks need enhanced adhesion and reduced water absorption before waterproofing.
The Adheseal Solution
GP Primer ensures consistent membrane performance in exterior conditions by sealing the substrate effectively.
Best Practice Note
Prime in dry conditions; avoid rain exposure until membrane application.
Frequently Asked Questions
Can Gripset GP Primer be used externally?
Yes, it is suitable for both internal and external porous surfaces before membrane application.
How long before applying the membrane?
Typically 30–60 minutes under normal drying conditions; ensure the surface is fully dry before proceeding.
Can it be used over non-porous surfaces?
No, GP Primer is specifically formulated for porous substrates. Use a suitable non-porous primer for those surfaces.
