ides and stains are sometimes added. Natural clay tiles also withstand severe abrasive wear.

(2) Pavers. These may be either the porcelain or natural clay type, and are six square inches or more in facial area.

(3) Quarries. These are made from natural clays and have a dense body which makes them very durable. Brick red, buffs and chocolates are the colors most often made.


Clay tile should always be installed by experienced and reputable clay tile contractors. The Tile Council of America, made up of the 20 leading manufacturers of clay door and wall tile, publishes two specifications for tile settingethe Tile Handbook, which covers installations in cement beds, and K-400, which covers the use of adheswes and other thin setting bed methods and materials.

The owner, the architect and the general contractor should make certain that one or the other of these books is used as a guide for all installations.

The conventional method of installing clay tile is to set it in a cement bed. This gives a wall approximately one and a half inches in thickness, and a door about an inch and a quarter.

In the conventional method, wall tile is ordinarily set on metal lath over wood studs or furring. Very smooth monolithic concrete, brick, hollow clay block and concrete block also provide suitable surfaces for wall tile set in cement.

Floor tile can be set over wood construction, concrete slab or fill, and steel plate when the conventional method is used. This technique has been in use for centuries and the fact that tile set hundreds of years ago with it is still in place attests its value.

The adhesive method was first used in the late 1920's or early bill's and has been given full recognition by the industry. It is particularly adapted to dry wall construction and to remodeling work.

The increase in the use of dry wall has markedly stepped up the demand for adhesive installations of clay tile. In new work, the tile is usually applied over gypsum wall board or gypsum plaster brown coat. A number of other surfaces have also been used and specifications for them are covered in the Tile Councilis th-4003i

On modernization projects, the tile contractor can install tile with adhesives directly over existing wall surfaces which are in proper condition. Under favorable conditions, adhesive manufacturers report up to 30 per cent savings with this method.

Whether the conventional or the mortar method is to be used should be a joint decision of the architect and the tile contractor.


Clay tile is one of the simplest and easiest maintained of all materials. Soapless detergents should always be used for it. Those cleansing agents consisting primarily of trisodium-phosphate are least expensive and highly satisfactory.

The detergent should be mixed with warm water according to the manufacturerls directions and allowed to remain on the tile door for a few minutes before mopping and rinsing. Trisodiumphosphate will not harm the tile or joints.

From time to time, if and as it seems necessary, a non -scratching soapless scouring powder should be used. Electric scrub brushes are helpful for large door areas. When they are used, care should be taken to avoid wearing away of the grout between tiles.

Adequate rinsing with clean hot water is absolutely necessary.

Do Not Use Soap

Frequent washing with soapeand particularly soap in conjunction with hard waterawill often build up a dirty film on tile doors. This sticky deposit, which consists of insoluble calcium and magnesium stearates, not only will pick up dirt but actually can make tile doors slippery. For these reasons soap should never be used.

If such a deposit has been built up on an existing door, it can be scoured off with a commercial cleansing powder. Kerosene will also remove the scummy film.

Avoid Floor Treating Agents

Waxes, plastic finishes, polishes, special emulsions, non-slip coatings, etc., should ordinarily be avoided. The original ceramic tile surface is ideal from the standpoint of walking safety, sanitation and ease of maintenance.

Special door treating compounds are therefore almost never required. Usually they detract in some way from the optimum performance of the door. Quite often their use leads to further undesirable psuedo-corrective treatments. Moreover, in some instances doors have actually been rendered unsafe by propri. etary preparations.

Whenever tile doors, whether paver, quarry or ceramic mosaic, seem slippery, greasy, scummy or dirty, give them a vigorous scrubbing with soapless detergent and scouring powder. Finally, rinse with lots of hot water.

Frequent cleaning thereafter insures easy maintenance. This old-fashioned method is economical and much more satisfactory than using expensive newfangled door compounds.
