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

As a DIY enthusiast, I recently tried the DAP 37584 Liquid Cement Crack Filler for some minor repairs around my home, and it exceeded my expectations. The application process was straightforward, and the consistency of the filler made it easy to pour and spread into the cracks. After drying, it blended seamlessly with the existing concrete, leaving a smooth, professional-looking finish. This product has saved me a lot of time and effort compared to traditional methods. It's durable and holds up well to weather changes, which is a huge plus. However, there are a few things to keep in mind. The color is a bit lighter than my older concrete, but it’s barely noticeable unless you’re looking closely. Also, it’s best used for smaller cracks; for wider gaps, you might need multiple applications to fill it properly. Despite these minor issues, the DAP Liquid Cement Crack Filler is a fantastic product that I highly recommend for anyone looking to do quick and effective concrete repairs. Pros: - Easy to apply and spread into cracks - Blends seamlessly with existing concrete - Provides a smooth, professional-looking finish - Durable and holds up well to weather changes Cons: - Color is slightly lighter than older concrete - Best suited for smaller cracks; may need multiple applications for wider gaps

Worked like it was supposed to. Be aware it will keep moving for several hours after it is put into gap. If you are trying to fill a hole you’ll probably need to refill at least once maybe twice over a couple of days. Otherwise really good product, dries lighter than surrounding concrete.

Super easy to use and could easily be rewarmed to be used multiple times. Lasted for multiple cracks across my back patio. Dried quickly. Color was slightly lighter than standard concrete.

Works as described. Settles into the 'cracks'. Warmer temps would probably make this work even better (I used it when temps were around 60)...

Looks great, easy to apply. Recommend for thin cracks not to wide. Quick drying.

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 used this on my porch that had a crack all the way across it. This was a deep crack but not very thick. I used painters tape to mask the sides of the crack and cleaned the crack out. Then poured this into the crack. After 30 mins I came back with a wet rag and cleaned up excess product being careful not to pull up product from the crack. It is mostly hardened by then but not fully set so being careful not to pull product from the crack but from the sides to keep the crack clean looking. Doing this keeps all the product in the crack and makes the crack invisible. Great product!

It is very effective in cleaning the grout. This is beneficial for a small area. If you have a large area to clean, I think the application of this is physically labor-intensive.
