Useal USA Hot Liquefied Rubber, Driveway Crack Sealer, 40 Ft #68118 (40 Ft)

This stuff is pretty good I have tried them all. The prep before putting this down is where the problem lies. I heated mine on the side burner on my grill, pretty good source of heat. Went thru the first 3 minutes to work the sides loose and all went fine, they say 12 minutes to heat the entire can it took me longer, but the big thing was the plastic spout they send is almost worthless ,it melted before I got the can to a working temperature. I took the can to the driveway with a pair of welding gloves. You can only pour a pool about the size of a beer can and work it quick because it will turn into rubber in around 1 minute. My saving grace was using a propane torch to remelt it and spread.

OK listen, I read the reviews and was fully aware of The apparent challenges this product presents when heating it up to get it to the liquid state. I was unprepared for just how much of an absolute nightmare it really is. I am a patient person. I bought two different canisters of the stuff from two different sellers at different times. The first one, I followed the directions of heating up directly on a burner. This was an absolute nightmare. Even on low heat, the bottom of the container closest to the heat turned into extremely viscous molten lava, while the top half remained nearly cold to the touch. Even after an hour of coaxing it with the heat going up and down and attempting to mix the still solid portions with the liquid portions, I was left with half of the container completely unusable because it wasn’t melted enough. On my second attempt, I tried the double boiler method. After an hour of having the container sit in boiling water, it was only about 2/3 of the way towards being at a usable melted status. Since it was somewhat gooey, I figured I could finish it off by applying it directly to the burner on medium heat. That did not work. The top half cooled faster than the entire thing was heating, so I was left in nearly the same position as the first batch. This stuff is just horrendous to work with. It is great once it’s in the crack you’re filling, but it’s not worth the effort in my opinion.

My use was to fill a crack that runs the width of my driveway (25' or so) and is about 1-1.5" wide. I have used several products in the past, so the bulk of the crack is filled, but the prior fixes all separated from the edges over time. The bulk is still filling the crack, with 1/8" to 1/4" cracks where it's separated. I left that bulk in the crack and planned to pour this over what was there so I didn't have to fill everything, just the cracks where it had separated. Note that I used up almost exactly one pot of this product.Product comes in a metal pot, filled to about 1/2" from the top. In the box is a piece of paper with additional instructions. I figured, "How hard could this be? You just heat it up!" so I didn't read that . I was wrong. Upon heating over a 12,000 BTU portable stove, I saw the tar in the center of the pot bulge up and over the side, and the sides of the pot bulge. Suspecting what was happening, I stepped back quite a bit. Good thing, since the gas that had formed due to high heat at the bottom of the pot finally got release in the form of a big "pssshhhtt" of flammable gas. Guess how I figured out it was flammable? Very exciting. Had I read the instructions, I would have known upon seeing the product rise up to take the pot off the heat and plunge a screwdriver or awl down the side to release the built up gas. This would have saved me a lot of aggravation. They also suggest using a water bath method which I imagine slows the rate of heat and prevents gas creation. So all of my issues with the product were the direct result of user error.Once I got the product melted, it flowed well, about the consistency of between ranch dressing and maple syrup. It's a little tricky to get it to form well, and I had a lot of droplets since I had messed up the pot during the gas expansion phase. I used a metal putty knife to smooth/spread it out to completely cover the target area and be somewhat consistent in coverage. Note it starts to harden almost immediately so pouring about 1-1.5' at a time then smooth with the putty gave a decent result. Pouring 3' then trying to smooth meant it was getting pretty gooey at the end. So pour 1.5', smooth, smooth, assess, pour 1.5', smooth, smooth, assess, etc..The product itself seems much better than the others I've tried, it really is like the stuff you see the road crews pouring on the highways and town roads. I think it will have much better durability than the pli-stixx (also a good product, just not as good) as well as the various formulations of epoxyish aggregates (although those are better for filling in a deep crack like mine).

Dangerous and poor value. The way the plastic handle attaches (poorly) BEFORE you put it over a heat source...to make molten lava.... To then carry with a poorly designed plastic handle... For about 20 feet of coverage for $30..... Is not worth it.

The end results are very pleasing but the process of heating this product is tedious.It takes approximately 45 minutes to "melt" the filler. This includes heating in a separate pot and boiling for about 30-35 minutes. The filler should be softened by this point so you put it directly on the heat source and stir for another 10 to 15 minutes. When liquefied you pour into the crack and follow along with a large putty knife you don't mind throwing out. You will have to put the crack filler back on a heat source to liquefy a couple of times throughout because as you empty the can it cools quickly and solidifies.At this point it may look a little sloppy with "dribbles" here and there and somewhat uneveness. What I love about this stuff is with the aid of a small propane torch it levels out mistakes and makes it look professionally done. This step can get smokey but will worth it.Overall I would recommend this product. Would have been five stars if it wasn't such a pain to heat up. Not sure how it will fare through the harsh winter months but I have high expectations.
