FAQ

I'm getting my bathroom shower tile installed and was told to get 4 sheets 1/2 thick backerboard with screws and I need to know if there is a difference between Cement Board and Backer Board?

Same thing. Backer board is a general term. Backer board can be 1/4 thick. can be a wood substrate used for tile is certain circumstances ( not yours), it can be the Hardi board which is a cementrous type board. Basically a backer board any thing that goes under any tile . You should get the cement board for your application. And if your doing a shower and he/she didn t suggest it, a vapor barrier is also needed under the cement board.in the shower area. Any questions you e mail me through my avatar and check my qualifications there. GL

How to open the cement board

Punch with a drill or a core. 1), small points of the hole, less than 30mm use the impact drill, see how much you play the hole, there are large and small impact drill, there are different diameter drill. 2), relatively large 50mm or so to use the core machine, according to the size of a variety of sizes and depth of the core machine.

What to use to fill gap between green wall board and cement board, and between cement boards around bath tub?

hi any flexible filler, but not silicon as this will collect the moisture and create mould

ok so im trying to attach the cooling fan to my cpu on my motherboard and i cant find any glue but i did find some patch cement in a road hazard kit, i was wondering if this would work or would my computer fry?

You need thermal paste. You can get a very small tube, enough for 1-3 applications (?) at COMPUSA (or other such place) for under $5. I work on m-boards/processors all the time and know that some kind of adhesive would probably ruin your computer. I've had many heat sinks/fans that would not separate from the processor, and sometimes lift it out of the socket without loosening the arm that tightens it. The kind of damage cant be (easily/cheaply) repaired. Get thermal paste, apply very thin amount to proc, covering the entire (proc) heat sink. Same to heat sink/fan.

What is the waterproof material for the bathroom wall?

Bathroom cut off the material three, tempered glass Tempered glass belongs to safety glass. In fact, the use of chemical or physical methods, the formation of compressive stress on the glass surface, the glass bear the external force when the first to offset the surface stress, thereby enhancing the carrying capacity, enhance the glass self-resistance Wind pressure, cold and heat, impact and so on. Flat steel, curved glass is a safety glass. Widely used in high-rise building doors and windows, glass curtain wall, indoor partition glass, lighting ceiling, sightseeing elevator channel, furniture, glass fence and so on.

do i need to put cementious backer board behind a fiberglass surround shower unit?

no,,not if its a full surround,,,use green board sheet rock around the edges though

If properly waterproofed/installed, will extreme temperatures still gradually warp cement backer boards and crack tile flooring? Thank you.

Ya don't need backer board for tile floors. A good coat of floor leveling mix (definitely not self-levelling whatever the name says) and a good mortar base with 1/4 trowel will work just fine. But durok is a cement product so it would only distort due to expansion and contraction which proper installation would minimize.

We are redoing a small bathroom and I want to redo the old tile and also add some additional tile around some of the other walls. We are planning to use cement board around the tub, but do I need to rip out existing wallboard around the vanity and other walls where I want to add new tiles and replace it with cement backer board? Or should I just add the cement board on top of the existing wallboard in the places I want to add new tile ( I was thinking about maybe tiling halfway up some of the other walls). Thanks!

Cement board is only needed around a tub or shower, Adhere the tile with a modified thinset adhesive. Use mastic (glue made for tile) on the existing drywall rather than thinset on the rest of the room.
