Tile over a cracked cement floor

I know cracks in a basement cement floor can and probably will work up into tile applied over them. Can I use sheets of cement board and not attach them to the old floor, like a floating floor? Bond the edges together then set tile on top. This would allow the cracks to widen in the old slab and not affect the finished tile floor, possibly?

You can get a crack membrane to put over the cracks. First use a primer on the floor, this is a primer just for this application, then put membrane on top of primer. these products can be found at home depot or lowes or any tile store.Also do not use cheep thinset. the better thinset is more flexible and will absorb any movement. The cement board would not work as they will move or flex and cause the grout to crack and tile to loosen

    The membrane can be costly if your floor has several cracks. Another way to solve your problem is to use mastic and contractors paper. !. make sure you cut the paper to twice the width of the tile size that you will new laying. 2. Spread a thin coat of mastic over crack and make sure it is the width of your paper. Spread the crack from one end to the other. 3. Lay your paper down over the crack and use a flat towel to flatten paper over mastic and crack. this will insure that you get a good bond with no bubbles. 4. allow to dry before installing the tile over the area.

I have a Saltillo tile balcony and the tiles are popping. There are no expansion joints, could that be the cause?


who ever installed it probably didn't use a tile underlay like wonderboard or hardibacker. Also for areas like that you have to get the good thinset mortar like FLEXbond and the other thing too is Saltillo is not very user friendly when it comes to installing if you're not fast because its so porous i literally sucks the moisture from the mortar and there for doesnt bond to ur surface. If the thinset is thick and dry it aint gonna work. ALSO WITH SALTILLO YOU MUST HAVE 100% COVERAGE WITH THE THINSET.. Hollow tiles or no thinset under corners and what not just going to pop up. I butter the floor AND the back side of the tile when doing that type of tile. It's not very flat so there for you must have alot of thinset mortar under each and every tile. good luck. hope this helped. I been doing custom tile for 25 years so i got ya on this. Who ever was the installer lacked some knowledge on Saltillo. Tear it up and get something nicer.

3rd: Materials needed for Preparation- Hardy Backer Board(1/2"-3' x 5'). HardyBoard Screws, Unsanded Mastec, Spacers-Depending on Tile Spacing/size of Tiles, 1' x 4' boards. (Tools Needed- Drill, Chalkline, Measuring tape, 3/16 x 3/16 Trowel, 1/4 x 1/4 trowel).

Installation; )Preparation) 1- Apply a 3/16 x3/16 trowel of Unsanded mastecon floor before laying the Backerboard. Screw the Backer Board to the floor recessing screws.

Tile Installation:- 1st- Sand Mastec used for joints, and screw holes. 2nd- Sweep roome very good and vacuum very well. 3rd- Measure each wall to find the Center Point of the room.(I prefer nailing a board down across one side of the line to keep tiles straight, and butt tiles to the board, and put spacers in between tiles). I use a 1/4" trowel to butter tiles before laying. With using Spacers, buttering tiles, laying tiles.( I prefer using a 2 x 4 and tap tiles across with a rubber Mallet to keep all tiles same heigth). Let One side tiles laid for 24 hours. 4th- Then do the same thing with other side of line.

Finishing Project: Once all the tiles are set, and all spacers removed. Mix up color of Choice unsanded Grout, and follow Manufacturers mixture Specs. Use grout Float and fill Spacing between Tiles. Let dry for 15 minutes. Use bucket of Clean water and Big sponge rinsing frequently removing all Grout from Tiles. Let dry for 30 minutes, and clean tiles again with Clean Water. Let set overnight. Next day, take Clean towel and rub haze off the tiles. Lastly, Seal Tile and grout.

Enjoy your project, and the Satisfaction of doing it yourself. Hope i was some help!!

My MK370 tile saw has a burning smell and it is making a slight banging noise every 7-9 seconds. The saw is cutting tile fine otherwise.


The problem could be bad brushes. Otherwise, you are probably burning the windings inside your motor. The slight banding noise could be an issue with the bearings in the motor itself. In which case you will soon be replacing the motor, so... we'll hope the brushes prove bad.
Assuming the motor has brushes, there will be 2 semi-large buttons on the motor (one on each side). They are screws. Remove them and beneath each one is a "brush". They should be long, hard, crack free, and smooth on the bottom where they touch the rotor. If not, then replace them. Almost all motors used for tools have brushes and some motors require disassembly of the motor itself to replace the brushes, but in your case, it should be an easy job. I can see one of the buttons on the Amazon picture.

Wrong floor tile adhesive used. Contractor used timber floor adhesive instead of concrete. Some tiles cracking and adhesive not drying?


it depends on what kind of tiles they were. If they were soft tile, then they may crack anyway if the floor is not level, also if he made the floor uneven by using the adhesive they can crack. Many soft tiles are peel and stick and no adhesive is needed. If they were hard stone tiles then he should have been using grout to stick them down and grout the cracks in between as well. It sounds like you need to have someone else come in and re-access the problem as I can't see the whole situation, but it sounds like the tiles may need to come back up. You can either get the same guy to come back and fix his mistake or get some one else to fix it then go after him to messing it up. If you want to choose another person I recommend looking at www.superpages.com.

Wet saw not cutting material completely


It might need a new blade. But try putting an old tile or offcut behind the tile you are cutting. Make sure the table surface is clean and flat. Residue tends to build up around the front of the blade which could cause the tile to crack. The ryobi's have a habit of water getting into the motor and the bearing destroys itself. Next time you take the blade off, take of the blade support and put bearing grease behind the rubber washer. I've blown up two this year until I worked out what the problem was.

How to use Tile Saw


To cut a tile using a wet tile saw, measure the exact space in which the tile will fit. Cuts are usually along a perimeter, in a corner, or around an electrical outlet. Mark the line on the full-sized tile in grease pencil. Most saws will accommodate tiles up to 12 inches (30 cm) in size, but oversized saws can be rented for huge floor tiles. Wearing safety glasses, place the tile on the moveable platform, and line up the mark with the edge of the saw. With the motor running, slide the platform toward the blade with an even but gentle pressure. Since you are grinding the tile apart, ensure that the water have sufficient time to cool everything.
