Spray Painted brick wall is permanent

You need to take necessary precautions while you spray paint the wall. You must buy a good respirator mask and use it while spray painting a brick wall. The mask will protect you from the toxic materials released into the air while you paint. 

Look for signs of water damage

Bricks are the primary cause of leakages in a home. Other associated issues can be mold growth, damp walls, etc. Once you paint the wall, you will not be able to fix any of these issues.

Once a brick wall is constructed, you should let it dry completely. If you apply spray paint over a damp wall, it can cause a lot of problems for your home. It would help if you tried using spray paint that gives the water the required space to evaporate into the atmosphere. 


Water-soluble salts are found in brick walls. When the water from the bricks evaporates, the salts are left behind. It is important to wipe off these salts before you spray paint the brick wall. Suppose you apply the paint on an insufficiently prepared brick wall. The paint will start peeling off in the next few days. The walls will have adhesion issues due to the efflorescence or traces of any other loose matter on the wall. 


You will have to inspect the wall carefully and then decide the number of coats you should apply to the brick wall. Also, before spraying the paint on the brick wall, make sure that you remove all kinds of dust, mold, moss, etc., from the wall.

Clean the walls thoroughly

As stated before, cleaning the walls before applying the spray paint is quite important. Using a cleaning mixture to clean your brick wall thoroughly would be best. Also, it would help if you ideally used a water hose to clean the wall as the force of the water will remove all kinds of additional particles stuck to the brick wall. 

cleaning of the wall

You can create a soap-water mixture to remove salt deposits on the brick wall. However, it would be best if you avoided any cleaning solutions that have acid in them as they can destroy the quality of the brick wall. 

Check the Alkaline Levels

Before painting a brick wall, you should seriously check the alkalinity of the wall. Although bricks are typically neutral, the mortar in which they are installed contains several soluble mineral salts known as alkalis. 

Oil-based paint products are impacted by free alkalis, which eventually causes the paint coating to dissolve. This process is technically known as saponification. To avoid alkali-based paint failure, it is advised to apply an alkali-resistant primer.

Maintenance spends

Brick walls require regular maintenance. Spray paints are not as strong as regular paints. Hence, it would help if you repainted the brick walls regularly. Keeping the painted walls in good condition will keep your house safe from any externalities. 

Also, applying the spray paint well will save the brick wall from premature degradation. You must apply a primer before spraying the paint on the brick wall. A primer will make the paint stay for a longer duration and hence, will keep your walls healthy.

Use newspapers to protect the windows and doors

As we know, the kinds of spray paints used on a brick wall are permanent, and erasing them will be a challenge. Therefore, you should use unfolded pieces of newspaper to cover the wood of your doors and windows.

You can also use painter tapes to tape the newspapers along the boundary of the doors and windows. It would be best if you also protected any other area you don't wish to paint. 

Repair the cracks before painting

You must repair the cracks before applying spray paint to the brick wall. Cracks are the major source of degeneration of paint. You can use a scraper to open the cracks and brush out all the dust from inside the crack.

You can use a caulking gun to completely fill the crack with caulk, and then you will have to let the wall dry for 5 hours. You can then flatten the caulk by pressing it till it gets to the level of the wall. Now, you can spray the paint on the brick wall. 

The spraying motions

You need to take care of the motion in which you spray paint a brick wall. It would help if you went with a vertical spray pattern that you can easily make using your spray bottle. You can pick a corner of the wall to start with and create strips with spray, ensuring that the strips overlap. 

This way, you will not leave blank areas while painting the wall. Also, when using a spray bottle to paint the brick wall, you should ensure that the bottle is at least 6 to 12 inches away from the wall. It would be best if you also had a consistent speed so that the wall gets painted thoroughly. 

Use a brush to make corrections

When you use spray paint to paint a brick wall, some unreachable spots might be left behind. These areas generally include the side of the doors and windows. It would help if you had some precision in painting these areas.

However, if you use spray paint to paint the areas, you might even paint the wooden frame of the doors and windows. Hence, it would be best to use a small paintbrush to paint these areas. Also, you should ensure that you are applying the paint gently so that there are no brush marks on the wall. 

Add a second coat

Before adding a second coat, you should consult an architect or a mason. Once they recommend you double coat the wall or apply the paint again, you can use the same steps and spray the second coat of paint on the brick wall.
