How to Paint Masonry Walls
Various methods are usually required while painting different surfaces. A wall made of sheet-rock will require a different process to be painted then one made of bricks. Painting a wall made of bricks or a masonry wall requires quite a bit of an effort and is not very easy.
If you are looking to paint such a wall, you must know the process and be willing to put in some extra effort as opposed to any other paint project. If you follow all the right methods then you should be able to do it without much trouble.

1
Prepare
If the wall has been painted before, you will need to remove any peelings that are on the wall. Use a scraper for this purpose. In case it is being painted for the first time, water it well before you start the process. Once it is dry, sand it with a paint grade sander. It takes quite a bit of effort and will take time so be mentally prepared for that. Be sure to wear gloves as you can get friction burns. -
2
Use a Sealer
A wall made of bricks will take a lot more paint than one made of wood. So be sure to put on a sealant before painting such a wall. It will generally be a latex based product. Paint a coat of it on the wall so that the pores can be closed. Otherwise, it will drink up all the paint. -

Apply Primer
You can used an oil based primer or a latex based primer, whichever you prefer as both work equally well on the masonry wall. Use a roller or a brush to apply the coat. Generally one coat is sufficient and there is no need to sand down the wall between the application of the sealant and the primer. After the application, give a light sanding to the wall before you paint it to allow for better adhesion. -

Paint the Wall
Use a latex or oil based paint, again, as per your choice. Both will work well on a brick wall. If you use a brush, make sure that you use long strokes. Let the paint dry before having the new coat put up as you do not want to paint on a partially dried wall. It will cause the paint to start flaking. Very light sanding between coats is advisable on some surfaces.
