Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.

Things I really liked about this product:
1. It seems to work!
2. No noxious odors - There is a faint "something" in terms of smell, but definitely not unbearable in any way.
3. This consistency means application is easy. It really does have the consistency of store bought chocolate pudding after its been in the fridge. Kinda goopy, but easy enough to work with
4. Quick-ish dry and cure. I waited roughly 14 hrs between each coat (pretty thick coat at that).
My only negative doesn't have much to do with the performance of the product. Rather, I simply didn't need an entire gallon of this stuff. I wish there was an option to purchase it by the quart, as I think I used roughly 3/4 of a quart for my repair. I will undoubtedly have another use for it in the future, but right now, its just another paint can in the paint can area of my garage.
If you're trying to do what I did in terms of an interior basement foundation crack repair, give it a shot! It works!
Had to seal a barn foundation from water intrusion due to percolation.
Painted on three layers inside and 4 layers outside, both bonding the slab, mud sill and steel walls.
Looks and acts like a giant condom encapsulating the building.
No more water intrusion.
First off, apply this stuff to clean (scraped, sanded, or repatched holes in basement walls be they cinderblock or fieldstone) surfaces. In my case I had to scrape out the old lime based cement used in-between the fieldstone foundation of my community walled 120 year old, Brooklyn Brownstone, rowhouse because after so many years it just disintegrated, allowing moisture and water invasion. I plugged up the joints holes with hydraulic cement (relatively inexpensive, even on this site OR from a big box) let them dry because hydraulic cement dries so fast tyou can only use very small batches at a time. I did not say this was fast work, however it ain't rocket science either so all you need is time and patience. Though I did not need to do so, I covered my interior basement walls with Sakcrete "topping or patching" cement which is premixed and applies easily AND has a long work time to batch size ratio. I felt that the Liquid rubber foundation sealant product would have better "purchace" or attach better to the coated rock schist surface. That being said, after all surfaces were prepared it was a simple matter of applying (in my case with a whitewash brush but on flat surfaces such as a cement block wall, a roller with a medium "nap" will work fine) the material. I would recommend applying between 60 to 80 degrees F. for best, even drying times but of course humidity will be a factor. This product dries medium "tacky" so I would allow a few extra days drying time if that's within your work time frame and IF you intend to paint over the rubber material which is black. There is no reason NOT to,leave it black but I find a white or light color helps with light dissemination and seems a little more pleasant to look at.
Essentially, those are the instructions on the can but if you go to their website (also on the can and on Amazon's product webpage description) you can find more info on applications/ coatings, etc.!
I highly recommend this stuff, I've used many other brands in similar situations including the funny looking and sounding guy on TV in his "flexibly sealed rubber coated screen boat," and I find this material not only more effective but MUCH less expensive by far whilst being a far superior product to use.

As a test, I applied some liquid rubber directly to some scrap expanded polystyrene and it did not seem to react. But I would still avoid contact with non cured product just be be safe.
Just needs to be a lot cheaper.
