Polygem LCR Epoxy Crack Sealer Repair Paste, High-Strength 2-Part System, Cures Gray

Polygem LCR Epoxy Crack Sealer Repair Paste is a high-strength, two-part epoxy system designed for tough, long-lasting repairs on concrete and many other surfaces. This kit includes two 16-ounce containers—one Part A and one Part B—by weight. When mixed in equal parts, the epoxy forms a light gray paste that blends with most concrete, making it perfect for setting injection ports, sealing foundation cracks, and fixing driveways, sidewalks, patios, pools, and garage floors. It’s also great for wood rot repair, laminating, and patching metal or fiberglass. Mixing is simple: combine equal amounts of Part A and Part B using your own spatula or mixing stick. The easy 1:1 mix ratio gives you reliable results every time. After mixing, you have 20–30 minutes of working time to apply the paste before it sets. The epoxy cures fully in 24 hours, resulting in a sandable and paintable finish that’s durable and chemical-resistant. Once cured, any extra material can be removed with a grinder or masonry chisel and hammer—always wear eye or face protection for safety. This repair paste is suitable for DIYers and professionals and works for vertical and horizontal repairs. Please note: Mixing tools are not included; you will need to provide your own.
