I am planning a basement finishing project and would appreciate some advice regarding installing ceramic tiles in a bathroom.

I understand that ceramic tiles can easily be laid directly on top of a concrete slab, assuming that there are no dips or humps, i.e. the floor is flat (but not necessarily level). However, the level of the bathroom floor needs to be raised about 1.25" to match the flooring in the adjoining rooms.

According to various sources, concrete backerboard is the best choice for a DIY'er in a bathroom setting. I have read how to lay concrete backerboard underlayment on a plywood subfloor, but I have some questions about my specific application.

First, exactly how is the backerboard affixed to the concrete? Is a thinset adhesive used, along with a series of nails/screws?

Second, the concrete slab is currently painted with, I believe, a waterproof paint. Do I need to strip the paint off before laying the backerboard?

Third, since the floor needs to be raised about 1.25", I assume 2 layers of backerboard needs to be laid. How is the second layer affixed to the first layer?

Finally, what size gap is required between the backerboard and a wall to accomodate expansion/contraction? 0.5"?

Thanks in advance.

i dont think you should try the backerboard over your cement,what i would try is to use a self leveling cement to raise the level of your floor,i think the max you can do is 3/4".then use thin set to build it up the rest of the way.you might try calling a tile installer and ask for his input...goodluck

You could build up the inch/quater with mud,
that is sand, portland, and masonry cements
Try calling some retailers around you to see if they know any one who still does this type work. its the only way to acchive a true flat/level floor any more, trouble is, no one wants to pay the cost, its labor intensive
