I started remodeling my kitchen and am stuck on what to do with my drywall. The backsplash previously was a laminate sheet attached directly to the drywall.
We got it down with little issue and have sections repaired and ready to paint. However, I have a wall that I plan on laying glass tile and I have no idea how to 'prep' the drywall.
It currently has left over glue in areas, but also has all the drywall paper ripped off in the spots that the glue stuck to the laminate when being removed. I also found a very small amount of mildew damage ( 1/2" x 5") to the drywall directly behind the kitchen sink. It was limited to the paper mainly and I have removed it. I ran some caulk where the drywall meets the countertop to fill in some gaps 1/8-1/4" wide.
My questions/concerns are:
- Do I need to use sandpaper to remove the remaining glue/adhesive?
- Do I need to repair/prep the drywall where the paper is gone? Basically the entire wall (once I remove the glue).. And, what do I use to repair and prep for tiling?
- Is there anything special I can do to the area directly behind the sink to 'waterproof' that section?
Thank you in advance for helping me out!!
