I am repainting my house for the first time, the original paint is just under 10 years old.
The house has some sort of engineered wood fascia boards, but I am not sure of the specific brand/type. In some areas The exposed side on the bottom of the board appears to be very porous, just like if you had ripped a sheet of OSB and painted it. All the areas I've looked closely at have paint in the pores so I think they are probably original. Although it looks ripped, I don't believe they actually were.
One painter I had give me a quote mentioned edge sealing all of them. So I was wondering if they should actually be edge sealed and if so, with what? I was originally thinking exterior vinyl spackling, but could also use caulk.
