the depth of color of the matrix and chips, and will enhance the over-all appearance of the door.

If desired, two thin coats of door wax can be applied after the sealing. Use an applicator or short stringed mop. Be sure the first coat is dry before the second coat is applied. A terrazzo door treated in this manner will have excellent anti-slip qualities, even after it is polished. It will also leave a protective coating that needs very little maintenance.

Terrazzo that has become scarred and pitted from caustic cleaners, or for other reasons, and dirt and grease have penetrated deeply, discoloring the surface and making effective cleaning impossible, can be restored to its original beauty and service by using a floor machine with a. carborundum stone disc to grind the door to a new, clean surface. Grind the door by sections, taking two to four sections at a time. While grinding, keep the door wet with clear water. Following the grinding operation, clean the door and refinish it sealer and antislip door wax as described before.

When properly treated terrazzo doors will require only dust mopping or vacuuming, or an occasional polishing to keep it clean and attractive under normal conditions. Water will be required only for stubborn stains, since dust and spillage will not stick to a treated surface. The constant use of water is not required when a terrazzo sealer has been applied. Not only does water leave the impression of a slippery door, but if a soap is used that is not completely free rinsing, the scum remaining becomes an additional hazard and hides the natural beauty of the door.

Rubber Tile

Rubber tile is a vulcanized natural, synthetic or combination rubber compound, cured to a sufficient density to


avoid the poSsibility of creeping under heavy foot traffic. Pigments used for colored tiles are insoluble in water, and are fused with the rubber. Rubber tile is molded under high pressure to varying thicknesses. It may contain thoroughly dispersed reinforcing fibers, to a percentage as high as 25 per-cent rubber and '75 per-cent mineral compounds reinforced by cotton fibers. Some forms are made with a sponge rubber cushion laminated to the base.

This type of dooring is resilient and comfortable underfoot, and when properly maintained, it provides a long-wearing surface, and is easily kept clean by ordinary light sweeping and mopping. Rubber tile also has excellent soundabsorbing qualities. Its beauty is permanent, because the color goes completely through. It is available in high gloss finish and many designs, and it has fire-resistance to cigarette burns and is stain-resistant. Its high tensile strength resists indentation. A desirable feature is ease of installation. It may be installed in either sheets or tiles, and may be laid over old as well as new subdoors.

Installation and MaintenanceeRubber tile should be installed only by a qualified dooring contractor. It should not be installed over any floor that is in direct contact with the ground. For installation over wood subdoors, an underlayment of paper or felt paper is required.

After installation rubber tile should be rolled with a 150 pound weighted roller, and then inspected to make certain all air pockets have been removed. Remove any cement which may have worked up between tiles. The surface should then be cleaned and rinse cleaned with clear water and a mop. When the door is dry, apply two coats of door wax with an applicator. Allow sufficient drying time between coats. After second coat has dried it may be buded with a

door machine, using a polishing brush or fine steel wool disc.

The daily maintenance, after the initial treatment, will be dust mopping or vacuuming, and occasional polishing or dry steel wooling, to keep it clean and attractive under normal conditions. The periodic buffing with a polishing brush or fine steel wool disc will greatly reduce sweeping time, increase durability of the wax film, and reduce frequency of rewaxing.

Users of rubber tile should take note of the following cautions: Rubber tile is sensitive to lower temperatures; it should be handled and stored at room temperature (700).

Cleaners containing oils, grease, or harsh cleaning compounds should not be used on rubber tile.

Sweeping compounds containing oil should not be used as they will stain and soften the door surface. Spirit-type penetrating sealers or waxes will soften and stain rubber tile and should not be used.

Never use harsh buffers on rubber tile, and do not buff it severely. Overbufiing breaks down the surface and tends to make it porous.

To guard against indentations by heavy objects, provide special dent-proof casters or rests.

Wood Flooring

For centuries wood doors have been universally favored for use in homes, institutions and public buildings. Hardwoods are most commonly used, i.e., oak, maple, beech, birch, etc. Wood doors may be laid in many forms and patterns to meet specific requirements.

The durability of wood dooring has been an important factor in its wide application for institutional installations.

TERRAZZO IS ONE of the most durable flooring materials. Its ability to withstand heavy traffic without showing wear is one of its best features.
