I built a 28X17 foot deck about 25 years ago. The wood was stained...but it didn't last.
About 10 years later, Behr DeckOver was used to recoat the decking.
Today, I used the DeckOver to fill cracks, chips, and scrapes.
The stuff is amazing. Just brush it in to fill any crack or crevice and it looks like new again. I used less than a gallon to refurbish it today.
It comes in any choice of colors. Very good product.
