Concrete Block: one of the most common commercial and industrial building materials on the planet. It's cost-effective and looks good. Thing is, like other materials it can experience paint failure. There are a number of causes, which I will discuss below. I'm also going to give readers a few pointers on the steps that need to be undertaken to fix it.
You've got to inspect your interiors and exteriors. If you see any sort of damage, get in contact with a painting contractor, and they'll be able to diagnose the extent of the damage, and recommend how to fix it. If you sleep on this point, you'll be paying a lot of money down the line for repairs.
You're looking for cracks, moisture, chipped or bulging paint, etc. Keep in mind that some cracks can be caused by foundation settlement. Due note that if not properly patched, moisture can settle into those cracks and wreak havoc on the paint and block. Be sure to inspect the mortar joints, the spaces in between the block.
A professional is going to need to repair the concrete block. That service will typically be tuckpointing, or repointing—the re-application of mortar to the mortar joints. If you see gouges, holes, scratches, etc., have them filled with masonry material, otherwise, again, moisture will gain entry.
Once the repairs have been made, it's time to paint. And when you paint concrete block, you really have to make sure you penetrate the porous material with the coating. This will prevent moisture from intruding into the block. Textured block requires double the amount of primer and paint than you'd typically use with smooth concrete block.
