More shade than sun
Some Mold/Mildew
No previous stain

Underneath my rear deck is a patio. I have cleaned both the top and bottom of the deck. I will be staining the top and exterior with TWP 100. I would like to seal the underneath wood with something less expensive to protect it from mold/milder and algae and to make it look nice - it doesn't need to be a stain. What would you recommend?

Thanks!
