Water_resistant backer board, not drywall, should be used under tile that is likely to get wet (shower walls and bathroom floors, for example). Whether it's backer board, plywood, or concrete, the substrate needs to be sound, clean, and dimensionally stable. Surfaces need to be level or plumb and true to plane, as the pros say__that means no bumps. Wallpaper, loose plaster, flaking paint, peeling tiles or unsecured sheet flooring must be removed from the walls or floors that are to be tiled.
Tips: Wipe the ceramic tile in your shower with lemon oil twice a month to keep pesky water stains and mildew at bay. Protect your ceramic floors by placing throw rugs in high_dirt areas, such as by doors, in hallways and in front of kitchen work areas. Place felt pads under any hardwood or metal furniture that comes into contact with your ceramic floor.
