I have two decks that are about 7 or 8 years old. I had it stained in October 2019 with Vermont Natural Coatings Polywhey Almond brown (I have health problems and need something with low VC’s). It worked well but with the last couple really hard winters here the deck was needing it again so I had ordered the same stuff and had it applied again by a professional last September. He did a wonderful job and the deck looked great. The water beaded as it should.
The problem is this spring I noticed white areas under the eves (among other places) that looked as though they were never treated at all. Also one board looks as though it is oozing pitch. I have never had that happen before, let alone on a deck that is 7 or 8 years old. A new deck perhaps but one that is this old?
I am thinking I got a bad batch of stain. Has anyone else ever seen this before? Below are pictures of one deck and the board that is oozing. Another odd thing, one deck has heavy rubber traction mats on the steps and landing. Under them the deck still looks much better/stained.
Suggestions? Thoughts? Should I have that one board replaced?
