I came across some sub-siding today that I’m not familiar with. See the photo…
Here is the situation… I saw some large gaps in the siding seams, so I took a look to see if I could see house wrap of some type and there wasn’t any. The next thing I find is this board in the garage and the stamped print stating; “WATER REPELLENT” - that was refreshing, but I just want to be sure that this stuff is installed right.
That dark coating appears water repellent to me, but what I saw in the gap looked like a plain fiber board type product…is this stuff installed backwards or is it water repellent on both sides?
Thanks in advance.
