  • This is the most reasonably priced way to waterproof your basement!
Size: 5 Gallon
Considering the cost, the actual high quality of the product and the "relative" ease of application to exterior and interior walls; I believe this to be one of the BEST products on the marketplace! I am a retired licensed civil and mechanical engineer and in my late 60's, so I know and appreciate a good quality product when I see and use one!. I can afford to have someone else do my odd jobs or even quasi-major ones like basement waterproofing. However, I'm retired with too much time on my hands and this "waterproofing" job needed to be done so, in the interests of brevity here goes. 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. ... show more

Solid sealant. Easy to apply. Thick seal. 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.
