Anderson’s Blue Flexible Sealer – Underwater Pool Repair Adhesive (4 oz Tube)

Make fast, reliable, and long-lasting repairs around your pool or spa with Anderson’s Blue Flexible Sealer. This professional-grade, nitrile rubber–based adhesive and sealant is specially formulated to bond to nearly all pool surfaces—including vinyl liners—and remain flexible after curing. Whether you’re sealing a small leak above the waterline or making an emergency underwater repair, this sealer delivers dependable, leak-stopping performance.

Unlike rigid sealants that crack over time, Anderson’s Blue Flexible Sealer moves with your pool.
