J-B Weld 50177 25mL WaterWeld Waterproof Adhesive & Sealant Syringe

J-B Weld 50177 25mL WaterWeld Waterproof Adhesive & Sealant Syringe – World’s Strongest Bond

J-B Weld WaterWeld (50177) is a two-part, waterproof adhesive and sealant packaged in a dual-plunger syringe for clean 1:1 mixing. Designed for wet-area repairs, it bonds and seals on fiberglass, porcelain, acrylic, PVC/ plastic, vinyl, ceramic, wood, and common metals including aluminum and steel. From tubs and showers to pool fittings and sink surrounds, WaterWeld creates a dependable, watertight bond that sets in 5 minutes and cures in 1 hour. Once cured, it can be sanded and painted to match surrounding surfaces. The adhesive cures white and delivers up to 2,350 PSI of holding power, retaining strength above or below the water’s surface. A resealable cap prevents dry-out between jobs, and the included tray and stir stick make small-batch mixing fast and tidy.

For maintenance teams, installers, and advanced DIY users, the syringe format simplifies accurate dispensing in tight spaces while the fast cure keeps projects moving. Use it for tile edges, shower pans, pool fittings, PVC pipe and trim, countertops, and boat or RV fixtures where a durable waterproof seal is required.
