Mortar Fix
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.

Mortar Repair
Large and small cracks or spaces in the mortar of my brick home- probably from the house settling- I used this product to fill those cracks! It worked fine- easy to apply! My concern was with the color- I ordered limestone- my mortar is between a limestone and a light beige color- so the limestone color is off- but I used it anyway. I would like to see a color chart in the advertising of all the colors available - it would take the guess work out of ordering the right color- Thx

Color is as pictured
I bought the one that is colored limestone, but it looks silver next to my mortar. I'll take another picture in a week or so once it's had time to cure to see if it changes colors. Either way, it is exactly the color that is shown from the manufacturer in the pictures when it comes out of the tube.

Dried up on arrival.
Upon arrival the spout on the tube was bent at an odd angle. Checked it and it appeared okay, but when I attempted to use the product I discovered that it was dried solid and would not flow as it should. I ordered another product.

Not what I expected
The texture of this stuff is more like an adhesive than a mortar. It smears like glue rather than a filler.

Works well for repairing cement cracks
It is a very good product, but it was hard to get out of the tube, maybe old stock, I took care of this issue by letting it warm up in the Sun for a couple of hours before applying to the cement driveway cracks.

Easy to use
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
