10.1 fl. oz. Rapid Set Self-Leveling Sealant (Sandstone)

Recommended with some cautionary notes... I used Rapid Set Self Leveling Sealant in Sandstone and Grey to repair mortar joints on a patio with brick pavers (horizontal brick is rarely a good idea). The stuff is runny, especially the first 12 - 20 inches of bead. It separates in the tube, so plan on wasting a squeeze or two before you get consistent product. The good thing about being runny is that it penetrates downward into cracks better than regular caulk. The bad things are that: 1. It has no body to adhere in a large crack and fill it by bridging to the sides and supporting itself like regular caulk can do, 2. It drips after you stop running the bead even if you release the pressure on the caulk gun...so you get drops and strings in places you don't want _ it's messy, 3. Forget about vertical cracks, it simply runs out unless it is a very small crack, 4. If you have deep cracks or ones that open below to empty space, this stuff will flow all the way to the lowest point before it fills up the crack, so be sure to stuff the crack before you start (true for any caulk work, but more so for Rapid Set.) On the plus side, it is sticky...I can't get it off me even with Goof Off and shop cleaner. P.S. Neither Sandstone or Grey matches the Buff mortar on my patio. Grey is close for regular concrete. I pressed some buff mortar from the bag used to install the patio into the Sandstone caulk to try to get a better color match.

I am one of those who sometimes uses items for things other than what is listed on the product. This time, I decided to try the Rapid Set Self-Leveling Sealant in Sandstone to fix a folding table that was still good but the support for the legs was constantly falling out of the holes. So, I set to work to fix that so that I could, once again, use the table. The first thing I noticed about this sealant was that it was NOT caulking! I had to treat it differently. This sealant is more like glue. It is thin so you have to be careful not to put the plunger on the caulking gun to hard or too swiftly. Once I got the hang of using it, I was able to fill the holes where the supports sit and then set the supports and seal around them. Well, I have to tell you that this stuff really works!! My table is now usable and the seal is tight. I would recommend this product. Also, it was easy to clean up the mess I made before knowing that this was glue and not caulk!

Now here is a nice tube of sealent thats perfect for just about any job, it's Self Leveling ,Weather Resisting, Paintable and it holds firmly and Durable. You can use it on joints,to Fill Cracks, around the pool all kinds of stuff Brick, Concrete, Metal, Wood and according to the lable even Glass. The Cure Time is faster in the warm weather than the cold and of course Don't use when it's wet.

This was used to fill in cracks between pavers. It is easy to install and looks nice. Larger cracks may need filling more than once because it does settle. But that was expected and is okay. The question I can't answer is how durable it will be. How long does it last and how will it look a year from now? If you have a lot of cracks between pavers, you'll need a number of tubes of this.

Easy to use and levels very well . Fills voids and cracks easily .

Works great, but be sure to buy enough as it doesn't go that far.

It levels well, but please be warned that it's very liquid. Also the spout keeps leaking a bit after taking off the pressure by pulling back the caulk gun piston. So it can get a bit messy; have some rags nearby. It also separates (transparent brown liquid, like oil on peanut butter) easily - even after putting the tube down for 4 hrs (with a cap) it separate a.

I have a 28 year old concrete driveway, it is large, in total 1200 sf. It is 6” thick class a concrete. Driveway in decent shape, with cracking from heavy trucks. Live on Long Island, so we have the freeze thaw cycle. Wanted to keep water from getting in cracks, freezing and enlarging crack. So I purchased the crack chaser blade for 4.5” grinder, did the proper v cut on cracks, power washed, let dry, high presser air blow out cracks. Now to this crap product. Purchased 20 tubes in sandstone. First tube went in well, self leveled color good. Should have stopped there. All tubes from same lot. Most tubes came out like caulking, never settled, lumpy, some lighter some darker, even had two pink colors. Really looks like crap. Going to have to get the grinder out and remove this crap, also going to try to get my $150 back. Do yourself a favor, do not use this crap.
