I have a room in the basement with a concrete floor that slopes 2" over 11 feet. It's finished in that it has drywall, but there is no flooring yet. I need to raise the floor to be level. The room has a high corner.
Use dry pack mud to raise the floor to level. Use thinset on the floor prior to the deck mud to help it adhere.
- It's my understanding mud shouldn't touch drywall, so should I cut out the 2" of drywall where I need to level it?
- If I should cut out the drywall, should I put backer board in it's place? (2" of concrete would be over the footer 2x4.
- How thin can I go with deck mud? I've read the thinnest I can go is 3/4 of an inch. If that's true, what should I use to finish the last 3/4 of an inch where it feathers into the high corner?
Thank you for your help, any info or links will be appreciated.
