  • 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.

Seems these are hit or mis. I got one that was probably too old and the caulk didn't harden. Made a mess and had to go to the store to buy a different brand.

I used it on the exterior of my garage and it went on fine and looks good. The final characteristic is how long will it be good? Only time will tell.

This specific brand of coping is extremely thick! I don't think that that's a bad thing. The last tube that I bought from walmart spewed out even when I didn't want it to. This stuff gives your hands a work out. Only thing I spent like was the color. It's definetly not a white. More of a cream. It will work for us because this bathroom needs a complete remodel soon.

The price is great. The product is ok. I have used better caulks and cheaper ones also. I probably would try another brand /type If I had to do it again. Not a terrible product but not as good as others.

I ordered this product twice. One for my rental and then one for my house. I did the rental around 2-3 years ago. The silicon still looks the same. Great quality. No issues with debonding, leaking. Easy to apply. No harsh smell, and worth every penny.
