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.
From Mor-Flexx 12 -Pack 10.5-oz Exterior and Specialty White Paintable Latex Caulk
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.

Tools nicely! Easy to work with!
Would RecommendIt tools nicely. It’s more flexible than regular grout so it’s perfect for fixing cracked and missing grout. I used it to replace about 40 linear feet of cracked and chipped out grout and I am confident it will hold over the long run.
Best Caulk Repair Available
Amazing product I would highly recommend. Stays pliable and flexible preventing any cracking on a joint that expands or contracts with different seasons.
Locked, caulked and ready
