Smile Applying Sheetrock over perimeter concrete blocks.

What is the best method to install 1/4" sheetrock over cement block walls, the residential type that are decorative on the exterior, but just regular cement block on the interior. Does this wall need to be waterproofed or any kind of sound treatment before the sheetrock is installed? Do you have to drill and connect anchors or glue or what? What special care needs to be taken other than electrical wires in the wall if any? Most of the outside walls fall into this situation.

local building codes will decide if you have to insulate this wall.

Your best bet is to build a wall out of 2x4s or 2x2s and attach sheetrock to that.

A vapor barrier on the heated side of the wall is required.

Use greentreet lumber for your baseplate so you do not have an issue with water damage. Also, keep the sheetrock away from the floor by at least 1/2".

PS: 1/2" sheetrock is required for studwall application.

Thank you for your information. The house will be built on a slab and shot so it will never be exposed to rising water unless like in the time of Noah. We have built commercial buildings out of these blocks, though they were 12 inch as opposed to the 6 inch. The inside walls were just sealed and painted. We have never had a problem with moisture. However for looks, as it is an elegant home, I will probably do just as you said. Thanks again.
