Highly Recommend
Would RecommendThis stuff looks so much better than regular caulk or sealant for sealing around stone or faux stone. Charcoal matches a lot of stone applications. I love it!

I really like this stuff!
Would RecommendI heard about this stuff from a couple of pros I follow and they were right. This is such easy cleanup and really looks like mortar. I actually used it in my kitchen where the tile backsplash meets the countertop to give the appearance of grout but to provide the waterproofing of sealant. It looks excellent, so much better than silicone or even plain acrylic caulk. Highly recommend to anyone looking for a natural stone look.

Creates a Great Seal
Would RecommendThe caulk was recommended by our flooring installation contractor to create a seal between our masonry raised hearth and new laminate flooring. Install was simple, easy, and quick.

Garbage
Would Not RecommendPunctured the top as instructed but it squeezed out the bottom of the tube instead of the tip. Ruined the gun. Too hard to squeeze out anyway even if the tube wasn't defective. Waste of money.

Perfect match for old mortar
Would RecommendThis caulk matched our 100 year old + brick mortar almost exactly. It goes on very easily and doesn’t look like you caulked the wall. Blends in very well. It also seals extremely well.
Don't cut too much off the spout, less is more!
Would RecommendHad some mortar cracks to fill in brick wall was worried about the clean-up and the texture of product. it worked great had a great mortar like texture when finished and clean up was easy with a brush and water.
Good caulk, but takes 24 hours to be paint ready.
Would RecommendSo this is a great caulk. I am marking this 4 stars from 5 that this caulk will take 24 hours before it is paint ready. So when you are painting a concrete floor it will take you and entire day before you can work with this to finish your project. The caulk does a good job on concrete and adheres well when it is finished curing. I would use it again.
It works
Would RecommendWorked as advertised. Easy to use, easy to clean up.
The product is easy to work with.
Would RecommendI used to fill in a gap between the exterior side of a window and the stone façade on a house. It filled the gap and matched the cement well.
