Dap 18370 Self-Leveling Concrete 3.0 Sealant 9.0-Ounce

BEST TIP YOU'LL READ HERE (maybe)Pour a little course sand on this before it dries and it will blend in almost seamlessly with your concrete. I managed to repair more than a few cracks in my driveway and you'll have a hard time finding where I did it.

Works very well as a seal between by garage slap and driveway. Flows very well and sets up pretty quickly. I got about 7ft. per tube filling a 5/8" gap with backer rod. A couple of things I quickly learned. First, buy the backer rod slightly bigger than your gap. I should have ordered a 3/4" backer so I could squeeze it more tightly into the gap. In some spots it was barely touching the sides and when I added the sealant it sagged a little forcing me to add a fair amount of extra sealant to level the joint. Second, make sure the backer rod is level in the joint - if it's not level the resulting joint will look wavy and not smooth. Third, cut off the tip of the tube to leave a big 45 degree opening, don't be nervous and cut a small hole worrying that it will come out too fast. And punch a good few holes in the seal inside the tube - you want this stuff to come out fast and without you having to rupture yourself squeezing it out. Lastly, if you're doing a long run open a couple of tubes and have them ready - you can change tubes in a few seconds and keep the joint wet and flowing without an interruption. Get everything ready and then move fast with a generous amount of sealant; don't try to go back over it later. This stuff starts to set up pretty quickly and it won't flow well when placed over material that you put down earlier and is starting to get tacky. You get the best finish with one thick line of sealant. It will level itself out and look very smooth and professional. I did a one-car garage first and it took me 10 minutes and looked pretty good. When I did my two-car garage I ran the bead of sealant in less than 60 seconds and it was perfect. One last thing... if you don't want ants and junk in the joint cover it with a piece of clear plastic for a few hours to keep it clean.

This is not "self leveling", if you put to too much it will leave a hump.Ugly, does not match even close to concrete color, been down two weeks, still rubbery. evidently does not get hard.Took the power washer to it to see if it could be leveled out, nope AND it turned white!Bought some stuff at Lowes years ago for my last house, worked much better, wish I could remember the name.DO NOT WASTE YOUR MONEY!!!

After lots of trial and error with various products, I like this one best for filling driveway and sidewalk cracks. The self leveling is a real plus in that you don't have to try to force the product into the cracks. That said it can get a bit messy using a caulk gun if you are not careful where you are aiming it. It is, however, as easy or easier to apply than most other products I have used. It holds up really well and can be painted over. On one wider crack I even rubbed on a little sand to blend with the texture of the rest of the concrete in that area. Also, if you have a large or deep crack it will work best to do it in layers and let in dry in between.

Bought this 2.5 yrs ago and it is still working great.. Installed in Minnesota. I used this in the 1/2" gaps between sections of a cement sidewalk; and, at the street apron/curb which has a slight incline -- it stayed in place. Of course, add foam filler (as I did) if you have deep gaps. I probably poured this at most 1/2" thick/deep. I think this is great stuff.

I used this to caulk the gap between a concrete pool deck and a brick coping. The original work was done some time ago and I didn't have it redone because of the high cost. Also, I had no idea how to get a smooth, professional caulking job.Well, this does it. Out of the tube it's runny, like a heavy oil, and so it flows into every nook and cranny of the gap and within a few seconds, the surface smooths out and within 24 hours, it's pretty well dry. It's also easy to direct it where you want it. The color when dry is similar to the color of concrete, there seems to be a bit of brown in it also, so it looks suitable around concrete. It's paintable as well, although I did not paint it. Because it's a liquid, THIS WILL NOT WORK in vertical cracks.A couple tips when you use it:1) Use backer rod to keep the depth of the crack/joint to about 1/2".2) As you flow this into the joint, fill it up to the level you desire, don't add more later, the finish won't be as good3) Don't use this on a windy day, or there will be dust & dirt in the caulk surface4) It wipes away pretty easily, and if it dries a bit, you can use mineral spirits. If it dries completely, it is stuck onto concrete. It ain't coming off.5) You will use more of this than you think.6) If you are doing a lot of filling (like a swimming pool joint), the big home improvement stores sell this by the 6 & 12 pack, and it is considerably cheaper than buying it one at a time.This is good stuff. Highly recommended.

The Product was so difficult to squeeze from the tube I had to use two hands, it even had some chunks come out. it would not self level. Made a complete mess. That said, I had bought a tube from a big box store because I didn't think I had enough. That product came out from the tube easily and self leveled fine. So, the product may be good, but my rating is because I was sent an old dried up tube. I should have stopped using it and sent it back but I just threw it away, that's on me.

I used it to fill a crack in the driveway. I filled the crack which took about 5 min per section (1 tube per section). I gave it a few min to settle. It turns fairly low viscosity to self level. This caused some areas to create voids where the cracks were deeper. Then i filled the void sections with another pass. It seemed to level nicely, even with the second pass. The cracks weren’t big enough for backer rod, so that wasn’t an option.Last, I threw some coarse sand on top after only about 10-15 min (I saw another reviewer recommend this here). That did a really nice job of blending the area. Obviously you can still see the crack, but it’s all similar in color and texture. If this holds up for a few years, I’ll be very happy with it.

Easy to apply and levels very nicely. Would be nice if it came in a clear "color".

Great product for cold climate.
