Last summer, Old pine PT deck, powered wash and clean, then was told to stain with TWP with stain. Looked awesome, so proud......this spring, it has white all over it, looks like white paint splatter all over it, but NOT.

Tried to cover it up with more stain, but it won't take it. The white is smooth and slick, and won't take to the stain. I used the top of the line TWP with 3 year warranty. Anyone else ever have this problem???

It doesn't matter if it the shaded side or the sunny side, or if it was sprayed on like I did with the first gallon, or brushed on like I did with all the over areas. Doesn't matter if it was under a tree or not. put on thick or thin, it is everywhere on all 3 levels of my deck, but NOT on any of the upright underpending.
