ceramic tile water absorption?

Question

We just moved into a new home and I picked out ceramic tile that I thought had a more natural feel than glaze for the bathrooms. After actually walking on the floor, the tile felt a bit rough and dusty but now it doesn't (the floor may have actually been dusty or I might just have gotten used to it). I think that i might have picked out porous tile because when the floor gets a little wet, the tile seems to absorb the water. Is this damaging to the tile or floor beneath it or will the water eventually dry out?The saleswoman never informed me that this tile was special in any way. Thanks!

Answer 1

For sure the tile will dry out eventually. If it really concerns you, seal it... but then the roughness will go away and the tile will be a bit shiny... maybe not the look you want.
Not to worry, sounds like a nice tile surface to me...

Answer 2

ALL tile absorbs water. Some less than others, is all. Porcelain has the least amount of absorption-- less than 1/2 of 1". But quarry tile, slate and stone all take in a good deal of water.

To answer your question: yes, this moisture can and will, over time, make its way to your floor. Hopefully, your installer took the time to apply a waterproofing membrane beneath the thinset. This will protect your subfloor. Nonetheless, it's always a good idea to seal your tile and grout. Not all sealants leave a glossy haze-- ask your dealer for options.

Good luck!

Answer 3

I would definitely try to learn all I could about that product. It may need some sort of sealer that never got applied at installation time.

Answer 4

Well, I would think, as with regular concrete, it would begin to crack after awhile. Sounds like you need some sort of sealer that would not cause a "glaze" effect, but won't retain water.
