DAP 37584 Liquid Cement Crack Filler, 1 quart, Gray

Will be fixing a few cracks will follow to the letter hope all looks good.

Easy to use concrete crack filler. Filled all the cracks in my driveway and sidewalk. I let it dry for several hours to make sure it cured before I stepped on it, but probably didn't need that long. Make sure you shake well to mix the container before you use it, otherwise it'll be a little runny. Only downside, the bottle didn't come with a cap so make sure you use it all before it dries out.

Don’t waste money on the TikTok stuff this does the same exact job for half of the price. As for what it does, it fills cracks, it’s not meant for big jobs. It does a great job on making the garage floor look a little better after cracking I do recommend it to others

Nice

Great color harder to use that ones in gun but lighter and better looking

I was going to use outdoor silicone for my concrete driveway gaps, but decided to give three bottles of this a whirl. This Dap product has the advantage of being super thin when it comes out of the bottle tip (unlike silicone, which is thick) so that I can use this for finer cracks and it works itself down in there. That said, for some reason, it doesn't seem to fill the cracks well. I have sections of 1/8 to 1/4 inch cracks that I have gone over three times with this Dap juice, and it still has gaps in the crack. Agains, it's the seepage downward that is the key, and perhaps it's fine.I plan to use this for the deeper part of the cracks (it says on the bottle not to use for cracks greater than 1/2 inch wide). a couple of passes, and then clear silicone over the top of the crack with silicone canister and caulk gun.This stuff does dry in a few minutes. I can see why Amazon reviewers have mentioned that it was hard when they got it. I bought mine at a building store, so those are the three I used. I have another three from Amazon that sound good when I shake the bottle, but I will tell when I open it. You will use the entire bottle because you cannot cover it and save it, even for a half hour. So, just plan on using the entire thing before it hardens. Also, when you razor off the tip, make it smaller than you would a caulk cartridge of bathroom caulk or silicone. Why? The juice in here is thin, and I cut it too wide and it basically poured all over the edges of the cracks. Since it's thin, a small opening would have been better.Update: These Amazon bottles do not have any seal on the top. The ones I bought from a large home box store has seals inside the spout, sort of like builders' caulk or inside a new catsup bottle. Well, these were just open once one unscrews the spout top. Mine worked well, but I believe it to be slightly thicker than the ones from the home store, perhaps from being exposed to air to some degree. Amazon raised the price of these and they are more expensive than the home store by more than a buck (but there's no sales tax here). I would suggest either buying locally so you can assure freshness by shaking it to see if it's liquid and not hard and by unscrewing the spout to see if it is sealed, or buying exactly what you can use from Amazon, not a bottle more (and returning it if it's hardened already). You can always buy more, but this stuff is not going to store well.

I purchased this product to fill a rather large crack in the concrete floor of my shop. The crack I filled was anywhere from 1/4" to 3/8" wide. To seal this crack, I used a foam backer-rod prior to filling the crack with the Dap Liquid Crack Filler. I applied the filler up to the level of the concrete then allowed it to cure for a couple of days. There was some settling that occurred, which required I apply some more filler to make it level with the floor. I am very pleased with the outcome. The filler sets to a solid/hard state to match the concrete. Although the product is gray in color, it does not perfectly match the existing concrete floor. This is of no concern to me, however if you are looking for a perfect match in color, you will probably have to use actual concrete paste which will probably not match color either after it cures. Also, the CC paste will probably crack and pop-out eventually.

Product works as described. I just want to add that the bottle doesn't come with a cap. So it's won't seal once opened. You can see it in the photo. Options are to either unscrew the cap and pour it into a different container, or use one of those caulking tube caps. Gotta say though: Seriously? How much does it cost to provide a cap?
