Painting Concrete Blocks - Chemical Coating

Q. We are building a new horse stable with concrete block walls. What type of paint would be best suited for this? And do we need to prime the walls first?

A. In answering this question I am assuming that you are painting concrete blocks that are fully cured.

When painting the block walls I am assuming that you are painting the interior. If so then yes I do recommend using a primer prior to applying a top coating. By using a "moisture block" primer it will seal the block walls and keep moisture from seeping into the interior area and give a great foundation surface for painting.

After the application of the primer, the use of a high quality full gloss epoxy top coat will give you the protection, and durability that you need. The epoxies are used for interior applications such as these where high moisture may occur and, for their ability to resist soils and chemicals. Epoxies are also known for their excellent adhesion qualities. The full gloss will allow for easy cleaning, and maintenance.

Check with your local paint supplier to determine the products that would be best suited for this type of job

Please be aware that coatings and solvents are chemicals and therefore you should always pay attention to proper handling procedures and be prepared to wear protective clothing, such as respirators, gloves, coveralls, etc. For further information on the health and safety requirements of the coatings and solvents you wish to use we strongly advised you to contact your local coating supplier. If possible, go the extra step and look for this information on the website of the product vendor.
