" This was a first for me. I have very large basement wall that was constantly cold and Had moisture issues. Not really leaking , just when it rained hard for many many days it would moist blocks. I wanted to renovate the basement but I needed to seal it first, so today was the day. I read all the instructions that came with the kit, it was very thorough. Did exactly what it said and I think it went on beautifully. I was real pleased with the outcome . The only issue I had was getting those temperatures right during January . Especially a block wall? The only thing I would add to the reading material is how to tell when one of the tank is running out. I figured that out on my own when it started spitting. "
