The Cure It Roofing Kit is a ready-to-use fiberglass-reinforced polymer (GRP) roofing system designed for DIY flat roof waterproofing and refurbishment. While popular in the United Kingdom and parts of Europe, it is also sought after by American homeowners and installers seeking a durable, resin-based solution for flat roofs, balconies, and walkable decks. This article explains what the Cure It Roofing Kit includes, how it works, installation steps, safety considerations, and practical tips for American projects, including compatibility with common substrates, maintenance, and cost considerations.
What Is the Cure It Roofing Kit
The Cure It Roofing Kit is a complete, resin-based GRP roofing system formulated to deliver a watertight, seamless membrane on flat or low-slope roofs. It relies on a polyester resin or vinyl ester resin combined with a reinforcing fiberglass mat and a protective topcoat. The kit typically includes resin, hardener, tissue or mat reinforcement, a topcoat, activators, sealants, and application accessories. The result is a lightweight, durable, UV-stable roof surface that can be walked on when fully cured.
Key Components and Their Roles
- Resin and Hardener: The epoxy- or polyester-based resin cures to form a tough, waterproof layer. The hardener enables the chemical reaction that hardens the resin.
- Fiberglass Reinforcement: Mat or tissue fabric provides structural strength and crack resistance, creating a unified membrane across irregularities.
- Topcoat: A UV-stable outer layer protects the membrane from sun exposure and weathering, extending service life.
- Detail Materials: Sealants, edge trims, and flashing tapes facilitate airtight, watertight joints around penetrations, parapets, and skirting boards.
- Application Accessories: Brush, roller, mixing cups, and spreader tools support even distribution and workability.
Advantages of Using Cure It on Flat Roofs
- Durability: The GRP membrane is resistant to wind, hail, and ponding water when properly installed.
- Lightweight: Heavier traditional roofing options aren’t required, making it suitable for structures with limited load capacity.
- Seamless Waterproofing: The cured membrane minimizes joints, reducing leak risk on flat roofs.
- Walkable Surface: Some formulations enable light foot traffic for maintenance access once fully cured.
- Repairability: Localized repairs can be applied without a full roof replacement.
Considerations for American Projects
American use presents specific considerations related to substrate compatibility, weather windows, and availability. The Cure It system requires proper surface preparation, bonding to compatible substrates (concrete, timber, ply, or existing roofing layers), and suitable curing conditions. Availability in the U.S. market may vary by supplier, and contractors should confirm resin types, cure times, and warranty terms with the importer or distributor. Local building codes and warranty requirements should be reviewed before installation.

- Site Preparation: Clear debris, ensure drainage, and repair any substrate delamination. Remove old coatings where necessary and correct moisture issues.
- Substrate Priming: Apply an appropriate primer to improve resin adhesion, especially on porous or glossy surfaces.
- Reinforcement Layering: Cut fiberglass fabric to fit roof contours and embed it into the resin. Overlap seams per guidelines to prevent gaps.
- Topcoat Application: Once the reinforcement layer cures, apply the protective topcoat in multiple coats for UV protection and durability.
- Detail Work: Seal around penetrations, upstands, and edges with compatible sealants and flashing tapes to ensure watertight joints.
- Curing and Conditioning: Allow sufficient cure time according to temperature and humidity. Keep the roof protected from foot traffic until fully cured.
Best Practices for DIY and Professional Installations
- Temperature and Humidity: Install within the recommended temperature range to ensure proper curing. Avoid installation during rain or freezing conditions.
- Ventilation and Safety: Work in a well-ventilated area; wear protective equipment and follow resin safety data sheets (SDS).
- Surface Preparation: Proper cleaning and priming are critical for adhesion and long-term performance.
- Thin-Coat Technique: Apply resin in thin, even coats to minimize air pockets and achieve a smooth membrane.
- Inspection: Inspect seams and Flashing thoroughly for continuity and signs of micro-leaks after curing.
Maintenance and Longevity
Routine maintenance includes inspecting the membrane for punctures, UV wear, or edge deterioration after severe weather. Clean gutters and drainage paths to prevent water pooling. If minor damage occurs, patch repairs with compatible resin and reinforcement material can extend the roof’s life. Typical service life for high-quality GRP roofs ranges from 15 to 25 years depending on climate, UV exposure, and installation quality.
Cost Considerations
Costs depend on kit contents, local supplier pricing, and project size. A Cure It Roofing Kit generally covers a defined roof area with considerations for waste, overlaps, and flashing. When budgeting, include primer, sealants, reinforcement fabric, topcoat, and any required tools. Labor costs vary; DIY installers can save but must weigh the risk of improper installation against professional installation guarantees.
Availability in the United States
While Cure It is more commonly available in the UK and parts of Europe, several U.S. distributors import GRP roofing systems or offer equivalent repair kits. Prospective buyers should verify product compatibility with local climate, warranty terms, and the availability of technical support. For a U.S.-based project, alternatives such as American-made GRP or other cold-applied liquid membranes may provide comparable performance and easier access to local support.
Choosing a Supplier and Getting Support
- Technical Documentation: Request product data sheets, application guides, and warranty details.
- Local Availability: Confirm shipping times, courier options, and return policies for the Cure It kit.
- Installation Training: Seek hands-on training or contractor recommendations to ensure proper technique.
- Warranty and Service: Ensure there is clear warranty coverage for water ingress and material defects.
Frequently Asked Questions
- Can Cure It be used on timber decks? Yes, with appropriate surface preparation and compatible primers and topcoats.
- Is Cure It walkable after curing? Some formulations allow light foot traffic; confirm specific guidance for the chosen kit and curing conditions.
- How long does curing take? Cure times depend on temperature and humidity; full cure may range from 24 to 72 hours or longer in cool, damp conditions.
Bottom Line
The Cure It Roofing Kit offers a robust, lightweight, and repairable solution for flat roof waterproofing using GRP technology. For American projects, success hinges on substrate compatibility, climate-appropriate application windows, and access to technical support familiar with local codes and warranty expectations. Whether pursued as a DIY project or via a licensed installer, understanding the kit components, proper surface preparation, and meticulous detailing is essential to achieving a durable, watertight roof.
