Frequently Asked Questions

We are pleased to provide answers to some of the most Frequently Asked Questions (FAQ) on a wide variety of our products.


Q. What is the difference between standard “ceramic” tiles and porcelain tiles?

Tile terminology can be confusing. Most types of tiles that are made from clay or a mixture of clay and other materials, then kiln-fired, are considered to be a part of the larger classification called “Ceramic Tiles”. These tiles can be split into two groups, porcelain tiles and non-porcelain tiles. These non-porcelain tiles are frequently referred to as ceramic tiles by themselves, separate from porcelain tiles.

“Ceramic” or non-porcelain tiles are generally made from red or white clay fired in a kiln. They are almost always finished with a durable glaze which carries the color and pattern. These tiles are used in both wall tile and floor tile applications, are softer and easier to cut than porcelain, and usually carry a PEI 0 to 3 rating. Non-porcelain ceramic tiles are usually suitable for very light to moderate traffic and generally have a relatively high water absorption rating making them less frost resistant and they are more prone to wear and chipping than porcelain tiles.

Porcelain tile is a tile that is generally made by the dust pressed method from porcelain clays which result in a tile that is dense, impervious, fine grained and smooth, with a sharply formed face. Porcelain tiles usually have a much lower water absorption rate (less than 0.5%) than non-porcelain tiles making them frost resistant or frost-proof. Glazed porcelain tiles are much harder and more wear and damage resistant than non-porcelain ceramic tiles, making them suitable for any application from light traffic to the heaviest residential and light commercial traffic. Full body porcelain tiles carry the color and pattern through the entire thickness of the tile making them virtually impervious to wear and are suitable for any application from residential to the highest traffic commercial or industrial applications. Porcelain tiles are available in matte, unglazed or a high polished finish.

Apart from our saltillo (clay) tile, Tile Expo chooses to offer our customers only the highest quality glazed and full body porcelain tiles to ensure years of worry free use, at prices comparable to or less than non-porcelain ceramic tiles.

Q. Can ceramic tile be used outdoors?

To be used outdoors, we recommend the tile must be frostproof and unglazed for floor use. Make sure the absorption rate is 0.5% or less.

Q. What is the difference between glazed and full-body tiles?

Glazed tiles are coated with a liquid glass, which is then baked into the surface of the clay. The glaze provides an unlimited array of colors and designs as well as protects the tile from staining. The unglazed tiles are pretty much the same as the glazed tile, except that their surface is not coated. Full-body porcelain tiles do not show wear because their color extends throughout the tile, making them ideal for commercial applications.

Q. Should a sealer be used on ceramic tile?
A glazed tile is already stain proof, so there is no purpose to putting on a sealer. You may put a penetrating sealer on your unglazed tile or your grout joints. The penetrating sealer is an invisible, stain resistant shield that is absorbed into the surface.

What is the difference between wall and floor tile?
Ceramic tile comes in either glazed or unglazed surfaces. The glazed surfaces are like glass and are best used on walls as they are too slippery for floor applications. Glazed ceramic tiles are also a little more susceptible to cracking.
When selecting any ceramic tile it is important to look at the PEI factor. This is the scratch resistance factor.
In our showroom we rate tiles form 1 to 5. As follows:
1= is ideal for walls.
2= is best for bathrooms and kitchens.
3= is appropriate for all residential applications
4 and 5= are applicable for commercial and heavy commercial applications, respectively.

What are the benefits of Tile over other floor coverings? There are many benefits. Tile is:
Safe – slip resistant
Non-conductive – will not produce a shock
An aid to insulation
Mechanically, one of the strongest surfacing materials
Ceramic tile improves air quality
Tile will not absorb odors. Therefore, smoke, paint fumes or other contaminants do not linger.
There are generally no fibers, gases or toxic by-products when installing ceramic tile.
Tile is chemically inert and inhibits the growth of mold, fungus and other viruses.
Reduction in allergies, improved air quality.
