Great caulk
I'm working on my deck and this caulk is great for fixing cracks. It's thicker than most caulk so get ready for hand cramps after you use it

Great for trailer repair
This is the only stuff that prevents leakage on trailer roofs! It adheres good but if it’s raining it won’t work. It does need dry weather to adhere. This is one my reorder list!

Solid as a rock, but flexible and fierce
WOW. What an awesome product. I used this to fill some gaps in my epdm pond liner (put seam tape over it after it cured, then coated with primer/neopond). The job was intimidating until Liquid Rubber came to the rescue. This stuff is a great adhesive AND waterproof rubber filler. What was once an anxious mess of an issue is now a breeze because of the liquid rubber suite of products. This caulk holds its shape, it sets up SO fast, and you can paint it in 24 hours. I mean WOW. I never thought I could be so excited about a waterproofing product, but I love this and Liquid Rubber earned a customer for life.

Waterproof and thick caulk
Liquid Rubber is an excellent product. Dries fast. Product is very thick and is hard to squeeze out of the tube. They have their own website and have great customer service. I also used liquid Rubber primer, colored water sealant, and the thermal fabric to waterproof a garage foundation.

Great product
Great seal and flexibility. Good adhesion. Nice to be able to just order and not have to go to the box store. Applies thick as needed. Value compared to store is equal. Wipes off like any other chalk or sealant.

Don't buy
Product was solidified in the tube and impossible to extract with a caulk gun.

Looks way better!
I had silicone caulking on my exterior door that kept yellowing and cracking. I wanted a better product that will last longer. Found the hybrid caulking from Liquid Rubber and gave it a shot. Sealed well but I like the adhesive part of it as well. My trim was loose and I couldn't put a screw in it. The caulking sealed and glued it together. Much better than before.

Very thick hard to push out of tube
Works well seals great but it’s a stiff product be sure to use in warmer weather so it’s easier to apply

Better than silicone
Excellent product. I used it to replace silicone caulking on a door sill which had started to leak after only six months. This clear caulking applies easily (I cleaned the area with rubbing alcohol first) and applied. Product is holding up just great against the elements. Yes, it is more expensive but well worth the additional money. Would be nice if it came in additional colours.
