Re:Doing Basement Bathroom-concrete board
Beer 4U2Hi All,
I am re:doing the basement bathroom with a combination of drywall on top and concrete board on the bottom near the concrete floor.
What do you use to fill and finish the seems between--Mortar
or drywall compound and synthetic tape or something else that I do not know about?
Should you finish off the concrete board as it's quite pitted with what material--drywall compound or ? Then paint.:PE:
Any ideas?
Thanks all

Randy can you describe for us a little better what you trying to accomplish? Are you planning on tiling the walls or just painting them? If just painting, then why are you using cement board?

Hi All,
I have/had a water problem, sometimes but not always.
I decided to concrete board as I got tired of replacing the drywall whenever it got wet and then moldy. I sealed the walls and shellaced the wood supports plus insulated with stryrofoam and plastic for vapour barrier. The sump pump is in the bathroom and I have a submersible sump with a flush covering made of plexiglass & vented. I will probably tile over it but it has hinges to open.
Hope you can picture it and I would like to make it as nice as possible and it may get wet so I will use a good bathroom paint for the moisture but first I have to finish the walls?
What to do?
Thx
Randy

Randy, anything that has tile or comes in direct contact with water, should have cement board, or a waterproofing membrane.
If you have that much moisture problems, I would install a good exhaust fan or get a good dehumidifier.
Can you take some pictures for us? Upload them to a photosharing site (photobucket, Flicker) and post the IMG url back here.

Hi, I cannot get my digital going therefore I will try to describe. The moisture is/was coming from wall seepage why I put concrete board on the bottom. Do you use compound and tape or is there a new product out there that is water resistant for the seems?

I'm imagining you used cbu along the bottom say 1ft of wall and you want to join it to regular sheetrock walls?
If so, finish it like a normal sheetrock joint, but jsut like sheetrock, it should not be installed directly against the floor, and for visible wall joints between cbu and sheetrock, I always use setting type compound (powdered form) which sets up much quicker. Wipe the cbu with a sponge first so it doesn't drink the moisture out of your compound. You might find (depending upon paint color) that you need a second coat of primer over the cbu.

Thanks,
exactly what I was looking for. Just thought there might be a new compound out there that was water proof, just in case it got that high but not likely!
I guess I am trying to be over constructive. Watching too much Holmes on homes.
The CBU has pits in it, just compound over them to finish?
Thx
