Sika - Sikacryl - Gray - Ready-Mix Concrete Patch - for Repairing spalls and Cracks in Concrete and Masonry - Textured - 1 qt (Pack of 1)

Goes on pink but dries white. It seems very sturdy and it dries quickly.

Easy work with and dries well. Ive bought 4 so far.

UPDATE: Might not have been the best idea for inside of the bird bath. Noticed the birds don’t frequent it as much. Will try to pressure wash off the inside or coat with something else. Purchased this concrete patch to repair a couple of small cracks in my concrete birdbath. Prepped the birdbath, cleaned, bleached and scrubbed. Took the air compressor and blew at the cracks to make sure nothing was left. Very easy to apply and appears to have done the trick. I let it cure for 48 hours to be on the safe side. I had planned to sand down a few rough edges, but hey it doesn’t have to be perfect for the birds and squirrels, so I skipped that. As other reviewers have mentioned the container leaks. First one I ordered had leaked out of the seal. On the replacement order they sent, same thing, but not as bad. So I made a judgement call and decided to use it. Product would probably benefit from having an inter foil seal on the container.

This stuff is awesome for repairs to hardy board. It’s dark gray fyi so it you’re using it on your concrete driveway it will stick out like a sore thumb.

Kyle used this to repair our concrete dining table after it took some damage during a move. It was effective both for patching cracks in the base and a chunk of the top that had crumbled as well. We opted for the kintsugi vibe and didn't paint the repaired area, but it finished smoothly with sanding and has withstood multiple relocations without cracking again. Drying time was a couple days to full hardness. Overall, easy to use and works great - this was a good buy.

powder mix might be easier and more permanent Filler Was too thick to spread into thin cracks on garage floor. Some pointers: dilute a bit at a time with enough water to preferred consistency Also, lightly mist concrete cracks before adding diluted filler so doesn’t dry up instantly in crack which interferes w adhesion I also misted after application.

Worked well to fix a flagstone masonry pillar, where some pieces had fallen off. It dried fast, and the flagstone pieces are sticking together. I smoothed out the finish by hand. One comment, though: it is definitely gray. Whereas what it replaced was a different mix of concrete that was more beige and had more sand in it. Few would notice, though, but me.

I saw the reviews claiming moisture turned the product into goo. I had some extra and let it dry for a few days then soaked it in a cup of water. I just pulled it out after a week and it is still rock hard. I think it needs to dry properly before any rain. If it doesn’t yes you will probably have a mess on your hands. Big box home stores sell it too but it was a couple dollars more when i checked.

Supero mis expectativas, en verdad es súper útil. Claro para los que no nos dedicamos a la obra, para ellos que saben, hacen su propia mezcla, pero este producto para los que no, en verdad súper genial.

Used to cover old railing holes, covered better then expected and dried hard. Even through heavy rain it held up. Drys very light grey not like cement so we ended up painting over it anyways

The product was as described and arrived on schedule.

its a good product, sealed my outside foundation crack, we will see if it holds over winter
