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
Would RecommendProduct was a simple fix to achieve professional finish
Works well but not perfect blend
Would RecommendItem used by me personally to fill in horizontal crack in stucco. Product was a little difficult to initially come out but afterwards was fine (suspect dry plug). Easy to smooth out but doesn't blend perfectly with surrounding stucco. I would say it blends 80%. If you want the stucco to blend perfectly I think a different stucco mix requiring mixing would be needed. However this is faster option. Works as advertised. If you want a decent job this is it but won't be perfect
Mortar caulk
Would RecommendWent on more smoothly than I thought. It just streamed out like frosting
excellent product
Would Recommendas easy to use as regular caulk. perfectly mimics the texture and final appearance of grout to create a more continuous effect than white or clear caulk
Good product.
Would RecommendEasy application and filled in cracked and missing mortar prior to painting brick.
Very satisfied with this product
Would RecommendProduct was easy to used with a caulk gun and results were very satisfactory. Used it on some concrete steps
Great mortar caulk!
Would RecommendThis works very good to point up mortar joints that are missing mortar.
Way easier than mixing mortar for small cracks
Would RecommendWent on easily, and looks close enough to mortar when it drys to make it worth the cost of the tube.
Looks just like mortar, but spreads like caulk.
Looks just like mortar, but spreads like caulk. Great stuff! Bought 2 tubes, only used one. Will keep the other for just such products soon!
