Ambiguity surrounding wall materials - Drywall, wallboard, sheetrock, plasterboard...

I'm new to home improvement and I gotta tell you, one of the things driving me absolutely crazy is all the ambiguity surrounding wall materials. It seems as though people are too quick to associate wall materials w/ brandnames like "sheetrock" and also to throw out alias names not realizing that there may be subtle important differences in the materials, like Plasterboard and drywall. Is there anywhere I can find a breakdown of different types of wall material and what the differences are? Thanks.

You can ask all the questions you like here and get some darn good answers.

Sheetrock and drywall are the same thing. (You are right, USG makes a brand line called sheetrock. dont get confused). It is made from gypsum sandwiched between paper. Comes in lengths from 8' to 16' long. It is usually 4' wide although you can buy it 54" wide for 9' ceilings.

There is no such animal as plaster board.

There is joint compound commonly refered to as mud. It comes in 3 different styles. All purpose, lightweight and topping. It is never called but sometimes confused for spackle. If you ask me (a drywall professional) about spackle, I wont respond to you. You should talk to a painter.

Plaster is a compound made from lime and sand (among other things). It is never called but sometimes confused for mud. Never ever say you are plastering drywall unless you are actually using plaster. Plaster comes in a powder form you mix with water and dries very hard.

There are a lot more things to know. If been in the business for 16 years and I am still learning. Today I finished (taped and mudded) sheetrock that was purple. New to me.

.
Even a lot of painters [me in particular] hardly ever use spackling but prefer instead to use joint compound, does the same job but can also be used for the drywall repairs that come up from time to time [especially with repaints]

That would be nationgypsum's Xp line of mold and mildew resistant wallboard. They come in HiAbuse and HiImpact. I've been told they are replacing greenboard for most non-backerboard bathroom applications.


Oh, and yes Wayne, BlueBoard is most definitely known by many as pasterboard.
