Our house was built in the 60s with Masonite (may not actually be Masonite, but you get the idea) siding. In the past few years, some of the siding has been damaged due to old cables being removed and my dogs gnawing on a few edges. The siding itself is still in good condition, but some small areas/patches have the interior of the siding exposed. Of course, it has a rough texture and needs to be sealed against moisture.
What’s the best way to do this? I could apply a primer or sealer, but that won’t help the texture. I guess I could use joint compound, but I’m not sure it would last in the exterior environment. Would a pro painter just say, “I’ll take care of that for you for $X?”
Is there an experienced person out there who has dealt with this issue? The exterior is going to get painted soon, but I don’t want them painting a surface that looks like the inside of a biscuit.
