View Full Version : CBU or Floating Walls

I've got another thread going, but now that my CBU is up and taped, this question is off-topic for my project.

After spending many hours cutting and hanging CBU (wonderboard), followed by several more hours of taping and jamming thinset into the joints, I am wordering if I shouldn't have just floated the whole wall and do away with measuring, cutting, changing blades, cutting, changing blades, trying to cut 3 inch strips for the door jambs and scew them into place without cracking them,etc, etc , etc., then taping and thinsetting the joints....you know where I am going.

Would it have been "easier" to float the whole thing? What do you pros use as decision making tools when deciding between a float job and CBU?

Decision comes from the Home owner.
A CBU shower takes 100.00 worth of material and about 100.00 in labor in my country to get the cbu up and taped.(about 1 1/2 hours tops)
Mud Walls are about 60.00 in materials and 450-500.00 in labor.Quite a differance.Guess which one most people pick ;)

Hey Brew, I'm with you. I hated hanging and messing with the CBU. When my project is done and I move on to the main bath, I'm gonna tackle a mud job on the bath splash.

Don't care if it takes me twice as long as cbu either. :D

Hey Dave, You could come on my next job.65 sheets of CBU on metal studs. By the time you were done you'd be so quick you would run out of screws before ya knew it. :D

How do you hang AND tape CBU on a 46 inch by 52 inch by 7 feet tall (or short depending on how vertically endowed/challenged you are) shower in 90 minutes? It took me almost that long to get 8 sheets of the stuff down into my basement. (ok, that's an exaggeration).

When floating walls, what to you put behind the lath to keep the lath flat and the mud in-place?
