Need Help on GoBoard to Drywall Transition
I think I've messed up a couple things here transitioning the goboard to drywall. Hoping to get some advice on here:
At this point, I've refilled the gap and taped with hot mud, and floated out the with regular all purpose mud. The tile I'm installing is going to come out to about the point where you can see the tape bump, and my intention was to finish floating out the wall to the right after. I assumed I needed to seal up th drywall compound with a primer, as its in a high moisture environment. I picked up Killz2 All Purpoose Primer.
-Im reading online that the thinset won't stick to killz, so I dont think I should put the primer on until the tile is up, so I dont apply it under where the tile will be put up accidentally.
-If I dont do anything to the all-purpose mud that is spread out on the goboard, won't it get moist behind the tile, soften, and create risk of the tile falling off the wall?
-Im thinking I should draw a line where the tile will be coming out to, then sand off the drywall compound as best I can up to that point. Is this the right way to handle this or should am I concerned over nothing?
