Worth the extra money!

I wasn't sure what to expect. Our deck is 3 years old. They used the other brand when it was built and most of the wood floor is cracking %26 splitting. First evening I pressure washed the deck. Next evening, I used my Mr clean sponge mop %26 a paint pan to apply. It Looks like thick milk or glue, so it's easy to see what you've covered. We will see if it lasts 6 years, but I'm very pleased with it today.

it arrived late and in a damaged box..paint can did not leak..those cans are tough..the damaged box wasn't human error it was most likely the weather or something that leaked when it rained 🤔
