Cure-It GRP Concrete Primer 5L

Cure-It GRP Concrete Primer is a specially formulated solution designed to prepare concrete surfaces before applying GRP (Glass Reinforced Plastic) systems. It acts as a vital first step to ensure proper bonding and long-lasting durability, giving you confidence that your GRP installation will stand the test of time. This primer is incredibly easy to use, making it a great choice for both professionals and experienced DIYers. Whether you're waterproofing a flat roof, lining a pond, or sealing a concrete tank, it simplifies the preparation process and helps ensure a smooth application. It’s suitable for a wide range of concrete-based projects, including ponds, swimming pools, water tanking systems, and other structural applications. Thanks to its versatility, it’s become a go-to product for many GRP installers. Clear and simple guidance charts are included to help you measure and mix the correct amount of hardener with your roofing resin and topcoat. This takes the guesswork out of the process and ensures consistent, reliable results. One of the key benefits of this primer is its ability to seal out lime from the concrete surface. Lime can interfere with GRP adhesion, so by locking it out, this primer helps create a stable and clean base for your GRP system.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
