Some homes feature an all-brick exterior while others have exterior brick accents. Painted brick has become a contemporary decorating trend. It is much cheaper for you to paint the brick on your home exterior than to hire a professional to do it. Follow the steps below to change the appearance of the exterior of your house without installing new siding.
You will need:
• Power circular or palm sander
• Pressure washer
• Paint scraper
• 100 percent acrylic caulk
• Acrylic mortar or mortar patch
• Latex or acrylic masonry primer
• Minimum 80 grit sandpaper
• 100 percent acrylic latex or elastomeric exterior house paint
• Paint roller
• ¾-inch or thicker roller cover
• Foam backer rod
• Soap for power washer
• Putty knife
• Drop cloths
Step 1: Set the pressure washer to between 1,500 and 2,000 psi. A higher setting could damage mortar. Use soap to tackle deposits of mildew and difficult efflorescence. You want to remove only the grime, dirt, and loose paint. Allow a few days for the porous brick to dry completely.
Step 2: Remove any remaining loose paint to prevent early chipping, using the paint scraper to remove larger pieces. Avoid using a wire brush because this can gouge or leave ruts in the brick.
Step 3: Attach the sandpaper to the sander and sand the brick until it is smooth.
Step 4: Repair any mortar that is missing or damaged. With a premixed acrylic mortar patch, you can prime and paint the brick as soon as the mortar is dry. Alternatively, you can create a powder mortar mixture that will dry in a few weeks.
Step 5: Place drop cloths on the ground around the project area. Paint the brick and mortar with the masonry primer. The topcoat will require 1 to 2 hours to dry. Prime the spots that previously featured mildew or efflorescence so you can apply an extra coat of primer, if required. Let the primer dry completely.
Step 6: Locate any holes that are 1/16-inch or larger and vacuum to remove dust from the area. Caulk the holes, using the putty knife to get the caulk into the cracks. Caulk around chimney caps, trim, windows, and doors. For bigger cracks, use the foam backer rod. Wait 3 to 5 hours and repeat the caulking job, if necessary.
Step 7: Paint the brick with the exterior house paint, rolling and brushing on the paint as you would on a flat wall. The thickness of the roller cover enables you to fill all the nooks and crannies in the bricks with paint. To make the brick most durable, apply two coats of paint.
