Cook Children's Hospital, Ft Worth Texas
This large project was completed in Elgin-Butler Brick's UltraMatte ceramic glazed finish to give it the soft look for a children's hospital. We refer to this type of glaze look as a stonetone finish because it has the look of natural stone, like limestone, but with a durable cleanable ceramic finish (not an engobe or slurry or clay coat). The brick is modular size in two custom colors #4066 Dust Storm which is a gray with a little brown in it also #4067 Winter Dawn which is white with some gray in it. The accent orange/red medallions are thin set ceramic tiles. At the rear of the hospital is the emergency entrance and parking deck area which is completed in 8" X 8" ceramic glazed units designed as large trees. The colors used were #7150 Ebony (matte black) and #7100 Winter White (matte while).

Cleaning
The glazed surface should be wiped clean after the joints are tooled or when the joints are thumbprint hard. Use a course rag such as burlap, corduroy or carpet. The longer the mortar remains on the surface the more difficult it will be to remove. Do not use metal scrapers or abrasive powders on the glazed brick. A wooden tool or paddle should be used to remove any mortar residue including lumps. Once the mortar joints have hardened the wall can be cleaned down with clean water and detergent using sponges or a clean cloth. For more difficult areas use a detergent-type masonry cleaner following the manufacturers directions carefully. Clean only small sections of one to two square yards at a time. It is very important to wet the wall before you begin and rinse immediately after with clean water. If a power-wash system is going to be used take special care not to damage the mortar joints. Always be careful not to etch or yellow the mortar joints with any cleaner. Acid washing is not recommended.
Glazed brick will last the life of the building and so will the masons workmanship. Taking a few steps to care for the material in advance and knowing how to deal with it at the jobsite will ensure a smooth flowing and great looking job.
