How to Replace Tile Floor?
Installing a new white tile floor is a great way to update a space. If the old tiles and subfloor are in good shape, then you can tile directly over them. Or, you can pull up the flooring and start over entirely from scratch. To lay your stone tiles, start by deciding on a pattern. Then, apply thin-set to the floor and set each tile down individually. Keep going until your floor is finished, wipe it down with a wet sponge, and admire your work.
Decide whether or not to tile directly on top of the prior layer. If the old Cement tile is securely installed and in good condition, you can save yourself a lot of time by just laying new tile on top of it. However, the floor level will change a bit. If you rip up the old tile, it will take more time, but you can guarantee that the subfloor is secure.
Tap each old tile lightly to check for looseness. Get a small wood mallet and tap the center of each wood tile. Listen closely to the noise that follows. If it sounds hollow, then you need to pull up the tile, spread a layer of thin-set underneath it, and press it back down.
Check the floor for levelness. Place a level down on the floor. Look at it to see if the floor reads out as perfectly level. Move your level device around to check all parts of the room. If there are high points in the room, use a masonry grinder to grind them down. If there are low points, plan to build them up with some extra thin-set before laying your new tile.
Sand the old tiles down. Get an 80-grit or rougher sand paper. Go over the room, sanding each area until all of the Wood Marble tile is a bit rough on the surface. Use a broom or vacuum to pick up any dust left over from sanding. The rougher texture of the tile will help the new tile to attach more securely to the floor.Before you start working, put on a pair of construction goggles to protect your eyes. Don protective gloves that fit you well, if you are worried about skin irritation.

Perform the concrete repairs and leveling. To lay an even surface, the underlying concrete needs to be uniform and level as well. To achieve this, get rid of any protrusions, bumps or cracks in the surface. Using sandpaper to level the bumps and concrete and other fillers to stop cracks, you should be able to get a smooth surface. Be sure to wash it after this is done and let it dry.

Use a poultice on resistant stains. Stains that do not want to disappear with regular cleaning and stain removal techniques require the use of a poultice. Make a paste out of cleaner and a powder, like talc, powdered chalk or dry kaolin clay. Spread the mixture over stains a 1⁄4 to 1⁄2 inch (0.64 to 1.27 cm) thick, cover with plastic wrap, and let it sit for 24 to 48 hours. Mix a 1⁄2 cup (120 mL) baking soda with 1 tablespoon (15 mL) water for oil stains. Mix a 1⁄2 cup (120 mL) talc with 1 tablespoon (15 mL) acetone for water-based stains.

Use your chisel to scrape off the mortar. Set the chisel blade on the surface next to the adhesive mortar. Apply a firm amount of pressure to the chisel, working in short back and forth motions to scrape the mortar off. Once you’ve removed it all, use a vacuum to get rid of the residue. Make sure the surface is completely smooth or else you won’t be able to lay another 
The proper alkaline or acid grout cleaner. Do not try to get the most aggressive acids or alkaline chemicals. Find an approved cleaner, perhaps at a local janitorial supply house. Mask areas you might be concerned with that could be harmed by chemicals. Stainless steel appliances need to be masked with plastic and taped. Carpet needs to be protected.
Sweep or vacuum area to be cleaned. Mix cleaning solution according to manufacturers directions. If you want to truly do your best you will use both an acid and an alkaline. If you have heavy grease use the alkaline first, if not use the acid first.
Apply solution to the grout joint and scrub with the grout brush. Use plenty of solution and let it dwell for at least 10 minutes, but do not let the solution dry. Add more if it is drying too fast, but keep it wet for 10 minutes at least. Your biggest advantage – beside using the correct supplies, is to let the chemical dwell. Dwell time is your friend.
After 10 minutes mop up slurry with clean water. You may also use a wet vac to remove slurry. Additional agitation with grout brush may be necessary. We suggest using microfiber mops. Repeat process if you are using alkaline as well as acid cleaners.
When your grout dries, if it is really clean, you may wish to add a sealer. We recommend a water based sealer as they are easier to work with when applying to a grout joint. Take care not to get sealer on the 
Use baking soda. Make a paste with baking soda and water. Apply it to the dirty grout using an old toothbrush. Scrub the paste into the grout well. Wash the grout with warm water when you are finished. Most dirty grout can be brightened using this natural method. For the tougher stains, allow the paste to sit for a few minutes before you start scrubbing.

If you don’t like using bleach, you may be able to find a commercial grout cleaner that will be stronger than a natural cleaning product. However, check the label to make sure it doesn’t list bleach as an ingredient.
