What You'll Need
Power washer
High gloss clear sealant

Glazed brick is a masonry material much like ceramic tile. Glazed brick has a hard glaze on top of the brick that is resistant to heat, weather, and chemicals. The glaze can be glossy like traditional ceramic tile or it can be decorative. Decorative glazes can be matte, mottled, or subtly sculpted.

Homeowners love glazed brick because it is very durable and can withstand a lot of abuse. However, like most masonry materials the look of glazed brick is not easily modified. The only way to change the color of glazed brick is to paint it. This is a very labor intensive project and will require continued maintenance. If you are up for the challenge you can darken the surface of your glazed brick.

Step 1—Clean the Brick

Before you apply paint to the glazed brick surface you should make sure that it is clean. If you are working with an exterior surface, it will probably be very large. In this case, you should use a power washer. This will allow you to adequately clean the brick in a relatively short amount of time.

If you are working with an interior surface, such as a fireplace, you can use a cleaner made for brick. In either case, you want the brick to dry completely after the cleaning.

Step 2—Prime the Brick

With an exterior surface, you must prime the brick before you paint it. You need a primer made specifically for masonry materials. The best primer to use in this case is going to be one designed for ceramic tile. A primer for ceramic tile will work best because it is produced specifically for a masonry material with a heavy glaze.

Apply the prime according to the manufacturer’s instructions. Generally, you will apply at least one coat of primer to the entire glazed brick surface. Before going on to the next step, you should let the primer dry completely.

Step 3—Paint the Brick

Once the primer has dried completely, you can begin painting the glazed brick surface. You should apply two coats of heavy duty exterior paint. You want to mix the paint thoroughly and roll it onto the surface of the brick. Because the glazed brick surface is not flat like walls, you may have to use your brush to cover the mortar joints. Because of the varied texture of the brick, the painting will generally take longer than if you were working on a flat surface.

Step 4—Coat the Brick

Once the paint has dried, seal the paint with a high gloss clear sealant. This can applied with a roller as well. The high gloss finish will give you the look of glazed brick. If you don’t want the glossy finish, select a sealant with a matte finish.

That’s it. You will need good weather and a few days to complete this entire project. However, you can definitely darken the color of your glazed brick with paint and primer.
