Due to a problem with my furnace, I recently had a lot of moisture get behind a wall and of course, mold to follow. All said and done I will need roughly 3 4x8 sheets to replace the damaged drywall.
My problem is they appear to have used 2 3/8" sheets stacked on one another, making it 3/4" total. All I can find around here is 5/8" boards. So, I need to make up a 1/16" difference. My friend suggested just mudding out the difference, but there is some large, older molding on the ceiling that i need to marry up to that makes that seem really difficult.
My thought was corrugated cardboard. But I saw this post and it didn't give a sure answer on whether or not that would be ok.
It mentions the cardboard giving too much and cracking the joints right away, but as I see it, the cardboard is thicker than what I need, so once it is compressed, it's not going anywhere. Any thoughts on what I should do?
