Why Choose Silicone Sealant?

  • WATERPROOF silicone sealant that’s made of 100% silicone with no fillers, delivering WATERTIGHT sealing 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 stain-free tub caulk protection against high temp, leaks, acid, and stain 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. Our bathroom caulking white has the ideal viscosity to be managed and shaped easily and won’t crack or shrink against UV or extreme temps.
