SIKASikaflex Mortar Fix - Limestone Polyurethane Sealant for Repairing Joints & Gaps in Mortar - 10.1 fl. oz - Flexible, Paintable, Textured for Seamless Blending (Pack of 12)

Mix black and white clay together, you get gray clay. That's what this looks like. Dries flexible, like thick rubber. Does not look like sand finish, more like a smooth cement finish. I would not use it for brick without adding sand into the finish. Look for videos on how to install this correctly. (tape edges, apply, press in to smooth, spray soapy water to control to finish etc.) You should also just try one tube to see what you are getting, before buying many tubes. (best product for filling the control joints in patio or sidewalk cracks, again look for videos to learn the technic for a pro finish)

Look at this as a grey version of construction adhesive. It works very well.

It fills cracks with gray goop that eventually cures and looks nothing like mortar

This is just the right texture & consistency for caulking the limestone of my house. There were hairline cracks in the limestone where I could see daylight from the garage to outside. Filling the cracks horizontally is easy with this product as it doesn’t easily leak out. I used this product name for self leveling sidewalks & the driveway also. Very happy with this brand. Be sure to use something such as paper towel or rag to catch the flow till you get it in the upright position. Otherwise quite messy.

Took longer than the tube said to cure but now that it's all set, it's all good now!

This product is very difficult to squeeze out of the tube. Great force must be applied to squeeze out a small drop. In addition, you must wear gloves as it is difficult to remove if it gets on you or anything else. I ended up throwing away my caulking gun as it got covered with this stuff. This stuff looks white and didn't blend in with other mortar. I ended up removing everything I applied and doing the job with Quickcrete Mortar. Much better.

I'm a novice at repairing mortar. I first tried a different brand that was easy to apply, but it was way too liquid-y. Then, I tried the Sikaflex and couldn't get it to come out of the container. I followed the instructions and punctured the seal as well as cut off the tip at the appropriate spot. It was almost impossible to get the product out of the tube. I can't tell if I'm just too weak, but I had a stronger friend also try and he had difficulty too. I was trying to fix a small gap that had developed between my house and my concrete walkway. Perhaps I purchased the wrong product, but after watching videos, this one seemed to be what I needed. With this product, I can't tell if I am too weak or if I received duds (I purchased 2 tubes). The expiration date was a year from the time I received them, so they weren't expired. My friend didn't think it should be so difficult to get the product out of the tube. I gave up and hired a professional. I wish I knew if the problem was with the product or with my friend and me.

Great product.I have used this in several different applications.Extremely durable and flexible.Use a wet finger to smooth out your joint.It is paintable if necessary.When using on a finished surface (visible and not paintable), throw play sand on the joint while sticky. This will help blend with the existing mortar.

Works as described and bought another one because it works so good and I need it!

Worked well easy to apply

It was very difficult to get the product to squeeze out of the tube, but once out it sticks well and does the job

Good

Its super easy to use. Just cut the top and squeeze it where you need it. I think for bigger holes its a little costly as you don't get that much in a tube. I do recommend it
