Hello,
I have tried to fix some areas of facial board and it doesn't seem to work.
I scrap old area away and used this product below. Then I sand and painted using Behr exterior paint. After a few months, the crack shows up again. The facial board is 2x6 (maybe douglas fir). I am thinking of using epoxy or maybe I need to prime the area.
