Worked great!
What I know about tiling you could put in a thimble. I needed something premixed for a smallish project. It worked well and was easy to work with.

Worked well for beginner rustic mosaic bricks
Let me start by saying this is my first time making mosaic bricks/stones. I used this mortar for the grout between the tiles, which I’m sure was exactly the wrong way to do it, but I did it anyway and it worked…

Not a true thinset but works
I’ve done floors for years and always referred to thinset as a mix that has no sand or such fine sand you can’t tell when you trowel it out. This stuff has a pretty coarse grit to it. Otherwise, it worked well…

THIS WORKS WONDERS. This is a good solid product. It is easy to apply. If you want the best color match, suggest that you drop a little colored sand over the area that you’re repairing that matches the area being repaired and you will have a great match. Highly recommended.

Solid Product. Works well. Color matched pretty well (it’ll fade over time). It’s malleable and easy to apply. It dries quickly, making it easier to apply over. All and all, an easy way to fix mortar joints and improve aesthetics.

Easy to use. More colors/blending would be nice. I changed my doorbell and used this to patch the holes in the mortar from the old one. Works great! Easy to apply and shape into a seamless finish to your existing mortar. I haven’t been through a winter yet, but it held up to summer sun and fall rain just fine.

Just What I Needed
I had to repair the front brick house steps. Some of the cement had come from between the brick and it looked really bad. These places also had the potential to hold water and if it froze later in the year the brick would have popped loose. This stuff was great. I was able to repair all of the crevices and spaces between the brick and it matched the original cement exactly. I was really surprised because the original cement was 15 years old. You can’t even tell where I patched several gapped areas of various sizes between the brick. I cut the tip at a slant which was really helpful when applying the mortar repair. Using the slanted tip made application easy between the brick without getting excess on the brick. I was able to actually just use my finger to smooth it out, make the curved trowel indentation between the brick and have it meet the brick and other mortar. Good stuff.
