Installing backer board

Hello, I'm in the process of installing ceramics in our kitchen/main floor...I just ripped out all the carpet and vinyl flooring, and the floor is to the subbfloor which is 3/4" OSB. I want to put in 1/2" cement board, but do not know which mortar to use on OSB. Also, once the mortar is applied, do you screww down the board right away with screws? Doesn't the mortar squish out the sides making it uneven...? Just curious. Back to the mortar...maybe I'm calling it the wrong stuff...Is it a glue based product? or a cement based product...? I want to stay clear of any "adhesive type" product.

Please help.

Rich

Let's try this again.

If the CBU's are installed per the manufacturers instructions it will be fine.

Can you use any other screw other than the durock rock-on screws?

The rock screws work better than all the others. The screws are made to countersink themselves into a CBU panel.

I'm in the same boat. My first time tiling, and I'm concerned b/c Lowes guy said that if I used thinset under the backerboard it would cause my underlayment to swell. Is this true? Can you tell me exactly what name brand stuff to put down under backerboard?

Thanks so much.
