Great question. First, not all ick is paintable. If you have access to the type of ick and manufacturer of the ick that covers your home, find out. If your ick is not damaged and looks good in its normal condition you may want to consider keeping it the way it is or just cleaning it because once you paint your ick, there's no going back. Why? According to the experts at This Old House, removing paint from ick, especially old ick on historic houses, will damage, crack and even erode the ick, which means costly repairs down the line.
Cleaning your ick may restore its beauty without the hassle of maintaining paint. However, cleaning icks often requires a professional – using a pressure or power washer the wrong way, will damage ick and mortar. Sometimes all it takes to remove that white chalky film on the outside (called efflorescence) is a wire ush.
If you decide to paint, you should first make sure that your mortar is in good condition. If your mortar is cracking, loose or missing, you will have to have it re-pointed before you paint. You must also use the right paint, and not paint that will seal the ick. Brick needs to “ eathe” because it is a porous surface and the wrong type of paint will peel or bubble over time.
Paint experts from major paint companies say to use an exterior ick primer, first. Most major paint companies make them. Apply the primer with a paint sprayer to coat the icks more evenly and quickly. After the primer is dry, use a spray painter to cover it with a coat or several coats (depending on coverage needed) of exterior masonry or ick paint. Again, most major paint companies make this type of paint. Ask your local paint store for more information.
