Good evening all,

I am in the process of re-staining a covered deck on the back of my house. The decking is T&G KDAT decking. After the first coats a lot of mud and dirt was all over it and it looked terrible. We recently cleaned it and applied some more Behr semi transparent stain. Is it okay to put a water seal over the stain? How can I protect this finish from foot traffic? Im trying to keep them in good looking appearance. 

Any help is greatly appreciated.

Thanks,
