You need 1 1/4" of subfloor. Typically it is 3/4" of plywood or OSB and 1/2" of mudbase or cement board.

Can you ceramic tile on plywood floor?

No, plywood alone is not strong enough for ceramic tile. These floors require a very sturdy subfloor at least 1 1/4" thick before the tile. This requires either using cement board or a pored mudbed.


How thick is a floor?

Not very thick. Many building codes (perhaps most) allow 3/4 inch waferboard or 5'8 inch plywood as the structural subfloor over 16" O.C. joists. This is fine for normal sized floors with carpet or vinyl overlay, but is insufficient for very large floors or floors to be finished in ceramic, slate or porcelain tiles.

Can ceramic floor tiles crack?

Probably, it depends on how thick the tiles are. But after awhile they will crack from the weight put on it.


What is the correct wax seal for a toilet flange that sits flush with the subfloor?

I would get the extra thick one. You should have to push down on the toilet to make the wax ring seal. If the toilet sits on the floor by itself, stack 2 rings on top of each other.

Which thin set do you use over plywood?

No. A subfloor needs to be 1 1/4" thick. Ceramic needs an extremely stable substrate. When thinset is added to the floor the water in the mixture weakens the plywood. Any flex in a subfloor will cause a tile to crack. Traditionally tile was placed on a mudbed. It was a cement mixture laid on the plywood at least 3/4" thick. Mudbeds are not for a do it yourselfer, since if the cement isn't mixed right or the floor is prepped incorrectly you can have a mess quickly. Today, a great many pros and the majority of DIY's use a cement board. There are several brand names on the market, Wonderboard, Hardibacker, Durock, etc. You apply a layer of thinset with 1/4" x 1/4" square notch trowel. The board is put over this and screwed into place. Some can be nailed, but screws are more reliable The seams are taped and mudded with a special mesh (similar to drywall tape) and thinset. The ceramic is then applied to the top of that with another layer of thinset. Depending on the thickness of the tile and original subfloor, you should end up with something around 1 1/2" to 1 3/4". There is a new generation of "cement board" but they can be quite costly. Schuter makes a product called Ditra that looks like a waffle pattern. You lay thinset on both sides. It will shave off a little in the height but is about 3x more expensive to use then cement board.


Why electrical current arc through the ceramic insulator?

There may be a crack in the ceramic. Also, all insulating materials have a dielectric breakdown voltage, often expressed in volts per mil (0.001 inch). For example barium titanate ceramic breaks down at 75 volts per mil. Thus a 0.5 inch thick insulator of barium titanate ceramic will withstand up to 37,500 volts.

That is the correct spelling of the word "enamel" (a thick paint, or the outer layer of a tooth).
