Questions About Tile

What could be causing cracks to appear in ceramic floor tiles?

There is always a remote possibility of an individual fractured tile, usually caused by not being bonded properly and then being impacted by an object dropping on it. That type of fracture is repaired by replacing the damaged tile. A sure rule of thumb to determining the problem: if the crack goes from one tile to another on a continuous line through the grout joint, the problem, without any doubt, is in the substrate; usually a crack in the slab. The damaged tile would have to be removed, a crack isolation membrane put down and the tile reinstalled; which should solve the problem.

Where would unglazed be preferable over glazed ceramic tile and why?

Unglazed ceramic tile is strongly recommended for most exterior horizontal (floor) applications, interior applications subject to standing water such as shower floors, for very high traffic floors such as airports, train stations, etc. Impervious porcelain tiles are recommended in all ’freeze/thaw‚ horizontal exterior applications, and even in vertical ’freeze/thaw‚ applications subject to standing (or in) water.

What type of tile is recommended for kitchen counter tops and why?

Although a great variety of glazed tiles are used for counter tops, manufacturers specifically recommend only specific tiles. These are usually double glazed or glazes fired at higher temperatures, such as glazes on vitreous and porcelain bodies. High–gloss glazes are not recommended because they will scratch under normal kitchen counter top use. Many owners will select these ’high–gloss‚ tiles for counter tops even though they are told “they will scratch,” because they like the look and do not intend to use their kitchen on a regular basis. Mohawk includes specific references in our catalog for each product. Refer to Mohawk Product Catalog. Vanity Tops: Most tiles are all right to use, except the softest glazes, because of less abuse.
