Liquid Cement Crack Filler (Ready to Use), Gray, 32 Oz (7079837584)

Works great filled in all the cracks

Super easy to use, although there were a couple big chunks that would not fit through the nozzle (even after cutting a big hole), so I had to take the whole cap off. Easy to spread with a putty knife. I used 3/4 of the bottle on the area in the photo. Worked perfect for all of the cracks-small and large… the rainwater just sat on top of it instead of soaking into the cracks of the concrete. Hallelujah. The next step is to use a concrete paint to paint the entire thing a solid color.

I have ordered a total of 5 of these in the last few months. The first three were of perfect consistency for filling concrete driveway cracks sized at 3/8 inch wide and deep. The last two, of which I ordered in September 2025 are too watery. Yes, I shook the bottles thoroughly each time I used the bottle. This resulted in tiny holes upon drying. I had to apply a second coat to these. I have done significant concrete crack filling. I am disappointed with the consistency of these last two batches!

I was doing some repairs by my garage and this worked great. After cleaning out the debris and dirt, this filled those cracks and made the driveway look better. It was pretty set within 90 minutes. And that night we had downpour of rain and it sealed well and held up great. Very happy with this item.

Works well to fill concrete cracks. I have fixed my back porch. This and not too runny. B hill

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.

Not much liquid in the bottle

Easy to use. Prep work is the hardest.

Excelente producto, cubre y sella muy bien las grietas, desde que lo puse no he tenido ningún problema de filtraciones. Si lo recomiendo.

Buen producto. Funciono donde un sellador no. No tan estetico pero funciono con lluvias pesadas en techo.

Fantástico

Útil,fácil de aplicar y muy maleable...

En serio líquido. No sirve más que en el suelo, no en paredes a no ser que apliques muy poco a una grieta nada profunda. Lleva una noche completa y aún no se ha endurecido bien.
