Polyester Resin and Hardener – 1 Gal.

Use it for: Laminating fiberglass cloth or mat Filling voids and surface defects Crack repairs in fiberglass or concrete Coating repairs around steps, corners, and fittings The resin sets in place quickly, cures with a tack-free finish, and sands easily, making it a trusted option for both preparation and finishing in pool restoration and other waterproofing projects. Features: Water-Resistant Bond: Ideal for wet environments like pools, spas, and boats Strong and Durable: High mechanical strength and chemical resistance Fast Curing: Sets quickly at room temperature User-Friendly: Compatible with most fiberglass cloths and fillers Cost-Effective: Industrial-grade quality for a competitive price Application Guide Surface Preparation: Ensure the surface is clean, dry, and free from grease, oil, or debris. Mixing: Add MEKP hardener (typically 1–2%) to the resin and stir thoroughly. Application: Use a brush, roller, or injection tool depending on your project. Apply immediately after mixing. Curing: Allow to cure at room temperature. Full cure occurs within 24 hours. Finishing: Sand and recoat or topcoat as needed. Note: Always wear protective gloves, goggles, and a respirator in a well-ventilated area. Frequently Asked Questions 1. Can this resin be used underwater during application? No. The surface must be completely dry for proper adhesion. Once fully cured, the resin becomes water-resistant. 2. What’s the difference between polyester resin and epoxy? Polyester resin cures faster, is more cost-effective, and is preferred for large-area lamination and repairs. Epoxy offers slightly better adhesion but at a higher cost. 3. How long is the working time after mixing the hardener? Working time (pot life) is typically 10–15 minutes, depending on temperature and hardener ratio.
