Drywall compound thickness
While doing some final finishing on drywall, I realized that a pedestal sink will be mounted to the wall, and that part of the wall is not planer. That is, due to a stud that is warped inward, there would be a 3/16″ gap at one end of the sink. I considered just using caulk, but the curve will be visible directly above the sink and below the mirror.
To make that area look flat, I’ll need to fill up to 1/4″.
I considered taking down the drywall and starting over, but that will add 1-2 weeks.
Can I just lay down 3, 1/16″ layers? I’ve never had to fill more than 1/8″ of compound, so just want to know if that much thickness will still stay in place?
Should I attach something like a lath /mesh to support that much compound?
