FAQ

Hi everybody! I just installed hardibacker boards in my bathroom. But I had to remove 1 pc 'coz I made a mistake. Can I still use it again? I screwed it every 8 inches around the edges and along every stud. Can I just cover the holes with thinset? Thanks!
just fill in the holes, as you tileing anyways, the cement will cover, any cracks up
do you use cement board behind shower walls?
Yes. Use cement board all around the shower/bath enclosure and use green board for the rest of the bathroom.
How do the fluorocarbon paint on the external wall of the cement pressure plate?
Metal paint: metal paint a + varnish together. Plain paint together, metal varnish together.
I want a smoother cut than I will get by scoring and breaking. Would I use an abrasive wheel in a circular saw or a diamond blade?
Masonry blade on a circular saw would do it. Clamp a board on the cement board and run the saw along it. take it slow and use several passes. You should get a fairly smooth/straight line.
i am wondering the durablability difference. Is one more sturdier than the other?
In a way, fiber cement board is better than stone veneer. Houses are rotting down everywhere stone veneer is installed incorrectly. There's a lot of hacks out there gluing the stuff straight onto wood, making it the next home repair nightmare. If done correctly, it might be more durable but it's not sturdier.

There's no requirement (USA) to put anything behind the durock located over your tub. If you're planning on using it (not already installed) I would consider switching to green board. It is much cheaper and most of all, lighter. Green board is only sheetrock that has been waterproofed - and it works well. If you are installing durock, ensure you securely attach it to the joists above the tub. Also, if installing any lights, fans etc over the tub, the sheetrock is much easier to cut and affix fixtures. Good luck
What is the national standard for the thickness and hardness of indoor residential cement?
The surface of the wall is the cement mortar leveling layer, the general thickness is not required, the mortar cement ratio, cement label, flatness and so on are required. Look at your situation, it should be cement mortar in the proportion of cement is too low, you can find the developer claims, but it is best private or to the local construction commission of the quality inspection station complaints, the court reluctant to accept these small cases, say the time Also can not afford to drag.
Does the cement board go over the lip of the tub, or does it sit on that lip?
it needs to go over it so water doesnt get behind it
