Fills mortar amazingly!
I was informed about this product by a builder friend of mine. Didn't really think it would work but got some on his suggestion. Wow was I surprised! It's an amazing product! Had some brick areas that had lost mortar over the last 20 years. Not only is it easy to work with, but it also perfectly matched the white color. It's gritty just like mortar! Cannot recommend this enough! Just get it!

Works well to patch small stucco cracks without having to do stucco work.
I have a stucco house that gets small cracks from time to time. My windows have a while stucco trim around them that was showing a lot of small cracks up to around 1/8" (1-2mm) and I was concerned about water and/or bugs finding their way in. Water will corrode your mesh and cause the stucco to start falling off so it's important to keep up on maintenance. I did a walk around with a tube of this stuff and just did a quick touch up on all of the cracks and it did a good job of disappearing into the stucco texture. I will be adding a coat of paint as soon as time permits which will further blend it in and ensure water resistance, but this was a quick and easy cosmetic as well as protective solution. I have a tube of tan caulk too that I will be using on the house as soon as I can get time off, hoping it matches as well.

Great for Stucco Repairs – Easy and Seamless
This stuff is fantastic for filling hairline cracks in stucco. It was super easy to apply—no mess, no fuss. The texture blends in perfectly with the surrounding surface, so the repair doesn’t stand out like a patch job. Highly recommend if you're looking for something that actually looks right once it dries.

buy this one if you need to fix stucco.....
Great stuff.... matched my "sand finished" stucco perfectly...... worth the money. It is not smooth but it is not supposed to be. Seems to be holding up exceptionally well too. I will say, if you are filling really small cracks, be sure to "smush" this in really well and feather it out. If you don't it will look like you have a worm trail under your stucco. Ask me how I know. :)
