Painting brick houses is something that you can do to improve its appearance. After all, if the bricks look worn down, damaged or otherwise unattractive, you can't really replace the bricks, but you can do the next best thing. Painting brick houses is a complicated, time consuming process. If you don't do it right, you may wind up constantly maintaining the coat of paint, which cost you more money than it's worth. But so long as you follow proper procedures, the results should be well worth your effort.
Preparing the Brick House for Painting
Before you begin paining a brick house, there are a couple of things that you must do to get the brick ready for painting.
- Remove foreign substances—scrape off any loose paint or any other foreign substance the may be stuck on the bricks using a scraper. If there is any mildew, you are better off using bleach. If you think your bricks have any lead-based paint, consult the specialist before you start removing it. Exposure the lead paint is hazardous to your health.
- Clean the brick—Use soap and water to wash off dirt that may have seeped into the brick's pores. When you are done, go over the bricks with water to remove any soap left behind.
- Patch the cracks—use either 100 percent acrylic or siliconized acrylic caulk to seal any cracks within the bricks. You may need to repeat this step several times, since the sealing material may not fully fill the cracks the first time around. For best results, wait at least 3 hours between applications.
Priming the Brick House
A primer is a coating material that helps paint stick to the surface of the brick, increases durability of the paint and provides some protection for the bricks underneath. Use the paint brush to apply the primer to the bricks. For best results, use an exterior latex primer. Be sure to be very thorough—if you leave any gaps, they will eventually show up on the coat of paint. You should be especially thorough with the sealing material between bricks, since the grout is more vulnerable than the bricks themselves.
After the primer is applied, wait until it is completely dried before you begin painting.
Painting the Brick House
Once the primer is completely dry, you can start painting using a paint brush. Be sure to have the color picked before you start painting. You can use either acrylic latex exterior paint or elastomeric paint. The later is more water-proof and is more suitable for repainting. In other words, if you decide to repaint your brick house with another color in the future, it would be easier to paint over.
After you applied one coat of paint, you may need to apply another to fill in the gaps. However, this may result in uneven surfaces, so you should try to be as thorough as possible the first time around.
Finishing the Process
Once your brick house is painted, wait for the paint to dry. Then, you can apply a coat of finish. You can choose from a variety of flat, satin, or semi-gloss finishes, depending on your preference.
