Customer Reviews for Rapid Set 10.1 fl. oz. Self-Leveling Sealant in 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.

In no way is this product tack free in 30 / 60 / 90 minutes, 24-48 hours later it will still be sticky. Not sure if the stock is old or the product is just difficult. I will say the product has a nice long work time.

Product is easy to put down and seals great. You just need to make sure there are no gaps because it is very liquid so you will waste a lot of you don’t have the gap closed.

I used this product in the gap between my brick patio and concrete pool deck. The old material was starting to crack, shrink, and allow water to penetrate under. I used a utility knife to completely remove the old substance by cutting along each side. I left the foam backer rod that was in place and filled in the gaps with play sand. Be sure to pack the area to prevent holes that this product will fill and will be wasted. I left about a 1/2" deep gap to be filled in with this product.

This worked great to fill a big crack in ceramic tile. It was easy to use and leveled out on its on.

The stuff works well, tho I’m not finished with my project bc they ran out. It is very seld settling, but it could actually be a little thicker. If there’s a small gap that runs into a hole or open area, it just keeps settling even with backer Rod. Therefore, you use probably 40% more. Then it can block more crevices instead on continuing to run somewhere under ground. That being said, I would buy again.

On clearance so it was discounted to almost nothing but the contents had turned to liquid so had to throw it out! Junk!

/Bought 2 cartridges; when one tube would not flow, I found the expiration date was 9/2020

It runs and doesn't stay where you want it to. I'm returning it. Even the one I opened is being returned. I am very disappointed in this product.

Excellent product. Be aware that self leveling also means somewhat viscous in order to do so. Plus never dries completely/totally hard, which is ok for allowing some expansion give & take.

Works perfect for filling in and leveling cracks and small imperfections with concrete sub floors. Only drawback is that it takes anywhere from 12-24 hours to cure to the touch.

Color changes To black within days

Great product for cracks in pavement. Has proper +- for contraction and expansion. Can be tooled if necessary. When installed to specifications will last for years.

Takes too long to dry

Worst product, comes out like paint, do not use on vertical surfaces. In hot weather, it does not live up to its name, there is no Rapid Set in this product, it is runny and drips over everything. Do not Buy!!!

As it’s mentioned in the product name, it’s a self-level sealant so it’s easy to use to fill in any expansion gaps that you don’t water gets in like in your driveway.

Works well for horizontal cracks

Worked better than I thought sealing up the cracks and expansion joints on my pool deck. Ended up buying more and doing my garage expansion joints as well.
