Sheetrock Guidelines in a Basement


We got flooded with Irene....I ripped out the lower 48" of rock . Time to rebuild.

Currently, there are 2 layers of 1/2 greenboard.

- is there TRUE benefits on the greenboard/purpleboard. I'm inclined to redo it in 2 layers of firecode as I like the better dentproofness

- how HIGH should I finish it off.
1/2" Gap to the floor
2" Gap to the floor (the benefit would be that if I ever got flooded again) at least the sheetrock might not be soaking it up like a sponge with the higher gap.

The baseboard of style is 3" flatstock but I can always do 3 1/2 or 4" flatstock to offset the gap.

Might want to check out paperless drywall.

A 2" gap seems excessive. Unless you fur the bottom edge back out, your base board can appear to cave into the wall at the bottom over time. The cost of replacement drywall is minimal at, what, $6/sheet?

Greenboard seems unnecessary. Its strength is when that it holds up better in damp environments, but I still doubt it would survive a flood (a wet environment). Is it just for peace of mind?

Out here, $10 a sheet.
Just came back looking at Denshield (which will require at least 2 skimcoats)..and that's at $20 a sheet.

I don't care about the materials.
The labor, the paint, the trim carpenter who comes behind that. OR even the fact that I mitigate the whole absorption issue ....so that I don't end up having to move everything .....as rock will need to get gutted again, etc//

Don't use DensShield on any below-grade exterior walls. 1/2" up on exterior walls is fine- no more. I would not use greenboard on the outside walls.
