I have old wood paneling that was painted with semi-gloss paint not too long ago.
We want to fill the grooves and make it look like drywall and smooth. I found this article.
It seems simple based on what they said: just basically fill with drywall compound. However, I have some doubts on cracking as someone mentioned in the Comment section.
If I nail the panel carefully everywhere to prevent movement, would drywall compound crack?
If I use the best non-crack compound, would it work?
I try to avoid using the caulking method as it's a large basement and there are many grooves to fill, plus it will stick out and then I have to use extra mud to fill them. I was thinking about tapes but it's kinda the same thing.
