Pre-Mixed Concrete Patch – Red Devil 0645 – Easy to Use and Durable

Michele E.Michele E.: I had three fine cracks in my concrete birdbath. I followed all the directions on the tube. The product sqeezed out easily and applied smoothly. It works. No leaks in the birdbath. I recommend it for small projects.

LaurieR: Small container and seems pricey for what you get. Also, it is such a pale grey color it just does not much the cement in the garage, sidewalk, driveway or steps. It doesn't spread easily nor smooth out and it cannot get down into the cracks very well just sits on top. It is too thick, needs to be a little thinner perhaps. Anyway I hate the look of it as it really stands out and looks worse that than before. Now I need to try to grind it off and use a product that is actually a cement grey. Not impressed with product and too pricey!

Scott S.: Used this to repair cracks and a few holes in my chimney crown before applying crown sealer. I prepared the crown and the cracks with a wire brush on my drill, then applied the cement. It took a few days to completely cure before I could apply the sealer, but it worked great. No issues with the filled holes, and the cement stuck firmly in the cracks. Good product, and easy to apply.

Amazon CustomerAmazon Customer: I gave 3 starts because although the product worked well, but the packaging and shipping/handling was poorly done. As shown in the pictures, the lid of the container couldn't hold the cement and opened during the shipping and spilled. There is no protective seal around the lid and the container was wrapped by a thin bubble wrap which was ripped in the box. I also need to mention that the box was crushed on one side which looked like the box was dropped.
I couldn't use all the cement because some part of it was already started hardening.
(1) The lid needs a protective seal.
(2) Better protective wrap and enough packaging fillers should be added to the box.
(3) Amazon should deliver these packages with more care.

Laura Earwicker: I had an old concrete planter which is maybe 3 feet tall. Over the years it had cracked, and sections fell out near the base.

I was about to discard it, but thought I'd try a tube of this stuff. I applied it with my hands (using gloves) and it almost immediately dried enough to hold the broken pieces back in place. I ran it along the chips and cracks and worked it in. The next day, it was fully dry and I touched up with additional paste.

I know it has to cure for a while, but after an overnight drying the planter seems pretty sturdy, and I'm so pleased I was able to fix it - not sure if the planter will survive past this season, but at least I got another year out of it, maybe more.

After using this paste (I bought the tube not the tub) I replaced the top and it did NOT dry out or clog the nozzle, I was easily able to squeeze more out.

LWS: Works fine. Difficult to spread and wants to clump. Working faster is helpful. Seems to hold up well.

Intheknow: Don't know about some of the negative reviews (some sound weird) but this stuff works as advertised. Filled in all holes, cracks, etc., on our concrete stoop and adjacent sidewalk. We then covered the entire front stoop with it and it looks great! What an improvement over the old pitted, cracked stoop. No, it doesn't look like we had a brand new concrete stoop poured but the improvement is so dramatic in appearance, so we're very pleased. Eventually we will need to have a new stoop poured but this is a nice stopgap. It was easy to use, very spreadable, and dries nicely. Again, some of the reviews that claim it doesn't work at all or that it never dries (huh?), I don't know where those people are coming from. Would recommend this product but use it for what it's meant for, not in a garage or something, or to secure a post in the ground, etc.. It won't work for those types of things and isn't meant for them anyway. And don't expect it to look like freshly poured concrete. It will look very nice and it's durable so for the money what more do you expect?! UPDATE: Two yand three ears later some of this product (*repairs") has cracked out. So, it held up for two years and then some, and...
