The Cure It Roofing System uses a specialized resin designed to create a durable, waterproof roof membrane. This guide explains what Cure It Roofing Resin is, how it works, where it fits in roof repairs and installations, and best practices for mixing, applying, and maintaining roofs protected by Cure It products. Understanding the resin’s properties, compatibility, and cure times helps homeowners and contractors achieve lasting, weather-resistant results.
What Is Cure It Roofing Resin
Cure It Roofing Resin is a high-build, UV-stable polyester or epoxy-based liquid resin formulated to work with Cure It’s multi-layer roofing membranes. It acts as the bonding and waterproofing layer that interlocks with fiberglass mat or protective topsides, forming a seamless, watertight sheet. The resin is designed to cure at ambient temperatures and remains flexible enough to tolerate typical U.S. weather cycles. It is commonly used in flat and pitched roof applications, including conservatories, extensions, and refurbishment projects where the Cure It system is specified.
Key Properties and Benefits
- Waterproof performance: Creates a resistant barrier against wind-driven rain and hail when fully cured.
- Chemical and UV stability: Maintains strength and color over years of sunlight exposure.
- Adhesion: Strong bond to cured resin, fiberglass, and various deck substrates when surface preparation is correct.
- Flexibility: Accommodates substrate movement without cracking.
- Repair-friendly: Suitable for localized repairs as part of an overall Cure It installation.
- Compatibility: Works as part of the Cure It resin and fleece system, ensuring predictable performance.
Mixing and Preparation Guidelines
Correct mixing is critical to achieving the intended cure and performance. Prepare all materials, tools, and working areas before mixing. Surface must be clean, dry, and free of loose particles. Use appropriate PPE, including gloves and eye protection, and mix in a well-ventilated area.
| Material | Ratio | Open Time | Cure Time |
|---|---|---|---|
| Cure It Roofing Resin | Specify per project guide | 5–15 minutes | 24–48 hours depending on temperature |
| Cure It Activator (if required) | As directed | — | — |
Note: Exact ratios and pot life vary by product version and environmental conditions. Always refer to the current Cure It technical data sheet (TDS) for the specific resin version used on the project. Temperature and humidity can shorten or extend open time and cure time.
Application Methods
Cure It Roofing Resin is typically applied after a suitable primer or fleece layer has established a sound base. The resin is brushed, rolled, or sprayed onto the prepared surface and then reinforced with the appropriate fiberglass fleece or mat, followed by additional resin application to saturate the reinforcement. Even coverage is essential to prevent dry spots that could lead to leaks. A second resin coat may be required to achieve the targeted thickness and waterproofing performance.
Step-by-Step Application Outline
- Prepare the roof surface: clean, repair, and wipe down to remove dust, oils, and loose material.
- Apply a primer if specified for the substrate and resin version.
- Mix resin and any activator according to the exact project guidelines.
- Apply the resin evenly using a roller or brush, ensuring complete saturation of the reinforcement.
- Place the fiberglass fleece or mat while the resin is still workable, then trowel or roll to eliminate air voids.
- Allow the first coat to cure to a tack-free state before applying a second coat if required.
Substrate Compatibility and Roof Types
Cure It Roofing Resin is designed for use with Cure It’s own deck and fleece systems, but substrate compatibility should always be confirmed. Common substrates include plywood, oriented strand board (OSB), metal, and certain concrete or screed bases. For pitched roofs, the resin provides additional protection when used with Cure It roof membranes. Flat roof renovations often rely on the resin to seal joints, seams, and penetrations. Always verify substrate suitability and ensure there is no moisture present before application.

Performance Considerations
In the United States, roof conditions such as temperature swings, UV exposure, and moisture cycles influence cure behavior. The resin’s performance hinges on proper surface preparation, correct mixing ratios, and complete saturation of reinforcement materials. Wet or humid conditions can extend cure times and reduce handling window. Conversely, high temperatures may speed up curing, requiring faster work pace and careful timing to avoid runs or sags. Environmental controls and adherence to the manufacturer’s guidelines are essential for optimal results.
Safety and Handling
Always follow the Safety Data Sheet (SDS) for the specific Cure It Roofing Resin product. PPE typically includes chemical-resistant gloves, eye protection, and respiratory protection in poorly ventilated areas. Store resin in a cool, dry place away from direct sunlight. Avoid skin contact and ensure proper disposal of any waste material according to local regulations. If skin contact occurs, wash with soap and water and seek medical advice if irritation persists.
Quality Control and Common Troubleshooting
- Uneven coverage: Rework areas with insufficient saturation; ensure consistent application technique and check for air voids under reinforcement.
- Bubbles or pinholes: Can indicate improper mixing or contamination; address by surface rework and controlled re-application.
- Adhesion failure: Verify substrate readiness, surface cleanliness, and appropriate primer use; ensure correct cure conditions are met.
- Early debonding: May result from movement in the substrate or inadequate consolidation of the reinforcement; consider additional bonding coats if allowed by the product guidelines.
Maintenance and Longevity
A well-installed Cure It Roofing Resin system can provide long-term waterproofing with reduced maintenance needs. Periodic inspections for signs of wear, UV degradation, or punctures are recommended. Prompt repairs with the appropriate resin products help maintain system integrity. In areas with extreme weather, consider a scheduled inspection after severe storms or heavy snowfall to ensure no damage has occurred at joints or penetrations.
FAQs and Common Questions
- Is Cure It Roofing Resin compatible with all Cure It membranes? It is designed for use with Cure It’s own fleece and membrane systems; always verify compatibility per the latest product documentation.
- Can I apply Cure It Resin in cold weather? Application in cooler temperatures is possible but may extend cure times and affect workability; follow the TDS for temperature limits.
- How thick should the resin coat be? Thickness depends on the reinforcement system and wind uplift requirements; refer to the project-specific thickness guidelines in the TDS.
- What safety precautions are essential? Use PPE, ensure ventilation, protect adjacent surfaces, and follow disposal guidelines for resin waste.
