Product Details
✓WATERPROOF silicone sealant with NO FILLERS, delivering watertight caulking sealant performance on indoor, outdoor, and submerged surfaces. Our white caulk is ideal for wood, glass, metal, plastic, tiles, and concrete.
✓LONG LASTING. Our white bathroom caulk safeguards RV windows, kitchen tiles, and shower floors and delivers caulk protection against high temp, leaks, acid, and stains for 25 years.
✓ODORLESS. Choose a weatherproof exterior caulk with NO CHEMICAL SMELL over a bathroom sealant that reeks of a sharp, acidic smell. Our marine caulk cures uniformly- is safe, and has no VOC.
✓ZERO-CLUMPING. We engineered a clog-free thermoplastic nozzle that allows our marine caulk to flow with just the right viscosity- never runny nor clumpy; it’s 100% Silicone with no fillers, so our RV caulk cures quickly.
✓NO SHRINKING MARINE SILICONE. Our white caulking for bathroom has the ideal viscosity to be managed and shaped easily and won’t crack or shrink against UV or extreme temps.
