NO MORE LEAKS IN MY BASEMENT

⭐️⭐️⭐️⭐️⭐️

I have had another product on my basement walls which has failed a few months after it has been applied.I used the SEMCO product and past few seasons absolutely no issues.

THE PERFECT SOLUTION

⭐️⭐️⭐️⭐️⭐️

Used another product from Home Depot to waterproof showers.Compared to my previous product, this doesn't have a strong odor and it goes on much easier.
