Painting brick walls exterior

"Ask yourself if you're covering up something that should be addressed separately, " says Crocker. He recommends getting in touch with the original owners or the builder who installed the brick, whenever possible, to uncover any problems that might arise. "You have to be very careful when you're changing the exterior makeup of a wall, " says Crocker.

Moisture is a concern that's usually apparent right off the bat. Water can enter brick through brick pores, incomplete mortar joints, sills, copings and other gaps. Make sure your brick is completely dry before you paint it — the risk of long-term or immediate damage is less likely.

The natural chemical property of bricks may affect your paint's durability as well. According to the Brick Industry Association, most bricks are neutral, but mortar often has a basic alkalinity. Paint products can be affected, so alkaline-resistant primer is usually recommended.

"Efflorescence" is a big word for that annoying white residue that often appears on older brick walls. This residue is made up of deposits of water-soluble salt buildup, often from moisture inside the brick. Remove the efflorescence with water and a stiff brush before painting your brick, and wait to see if it returns. If it does, you may have a bigger problem on your hands that requires professional help.

Shall I whitewash or paint my exterior brick wall?

Our house is made out of red brick (uniform shape, standard brick). It has an oblong brick outbuilding of the same type of brick attached to it which is used for storage etc,, but I think it looks boring and ugly from the outside. Our house is up for sale and we have had NO interest at all. I think it's because this outbuilding looks ugly and doesn't give the house much 'kerb appeal'. I'm thinking of either whitewashing or painting it then putting some hanging baskets full of flowers up to 'tart' it up a bit. Have heard painting can cause problems to brick, not to mention the upkeep. Sh…

oooh, i wouldn't paint those bricks at all. as a recent home-buyer, if i saw a house with painted bricks, i would consider that a shame. Bricks have a quaint appeal to them if surrounded by the right decor. i think if you try to fix the house up at all, look into other things.. like improving the yard, adding a garden, rocks, vines maybe. painting the trim may help too as well as adding lots of nice greenery like juniper or some trimmable bushes.

Why do people often paint the lowest course(s) of bricks black when painting exterior house walls?

Is this special paint to waterproof the wall or just for appearance?

i have never seen this, or at least never noticed it, but i would think that dirt and mud and stains get on the lowest brick layer when it rains, so painting them would not make the mess as noticeable.
