Glazed brick refers to bricks with a ceramic coating or finish applied to it then fixed on a second firing. These glazed bricks are sometimes treated in brilliant colors and are used for ornamental facades. These are stoneware treated to become brightly colored and useful in decorative facades. These are actually polychrome glazed bricks which were used in Assyrian and Babylonian architecture. For proper replacement and installation of new glazed bricks, the mason contractor should be familiar with the recommendations of the Brick Industry Association and requirements of the manufacturer. Make sure the materials are clean and dry or this can destroy the bricks. Ensure that these glazed units are not laid in extreme cold or hot weather conditions. If this is the case, take necessary precautions for such conditions so that the bricks are bonded properly. These bricks are very attractive, but can sometimes get ruined and destroyed and may need replacement in time. Here are the steps for replacement:

Step 1 – Remove Old Bricks

Once removed, lay the masonry plumb. Ensure that it’s level and straight as compared to the line. If not, determine where the walls are to be fixed for leveling and mend accordingly.

Step 2 – Install the Bricks

Install the glazed bricks in a bonding pattern. When cutting the units, use a masonry saw that has a wet diamond blade. Make sure you use bricks that are more than 4 inches in length.

Step 3 – Set the Bricks

Set the bricks with the cells running vertically. Laying it this way will allow drainage of moisture within the wall. Make sure to construct a wall cavity having a minimum 2 inch cavity. When installing, pay attention to areas where bulges or breaks exist. Be careful in handling the bricks to avoid slanting and crumbling. Protect the glazed units in the manufacturer’s wrapping until it's ready to be installed or set on the wall. When applying mortar to each brick, make sure to use with full head and bed joints. Keep the units plumb, square and level to the line when thrusting the brick into place. Finally, ensure hat you don’t use metal tools on the glazed brick’s face.

Step 4 – Install Vents

Install vents, flashing and weep holes by strictly following the Brick Industry Association guidelines. Be particular and ensure installation allow drainage to flashing then to the weep holes. Avoid using joint sealers on the exterior of the units. Give time for the wall to cure. Proper curing time would take 24 hours. Less than this and glazed brick walls might get damaged.

Step 5 – Clean the Walls

Clean the finished walls using water and applying the detergent solution. A stiff fiber brush can be used when cleaning.

Step 6 – Remove Mortar

Remove excess mortar from difficult areas using a wooden scraper.

Rinse the walls well with clean water to avoid residue. Make sure you don’t use acids or abrasive cleaners or this can destroy your glazed bricks.
