Painting interior cinder block walls is a simple and effective way to improve the appearance of a room. Here are the steps to follow:
1. Prepare the wall: Clean the surface with a wire brush to remove any loose dirt or debris. Fill any cracks or holes with a patching compound and sand it smooth.
2. Prime the wall: Apply a coat of masonry primer to ensure better paint adhesion and coverage. Use a roller for larger areas and a brush for corners and edges.
3. Choose the right paint: Select a high-quality latex paint formulated for masonry surfaces. Consider the desired color and finish, such as matte or satin.
4. Paint the wall: Start by cutting in along the edges with a brush, then use a roller to cover the rest of the wall. Apply two coats for better coverage, allowing sufficient drying time between coats.
5. Clean up: Clean your brushes and rollers with soap and water. Dispose of any leftover paint properly.
By following these steps, you can transform your interior cinder block walls and create a more appealing and polished living space.
Interior cinder block walls, also known as concrete masonry units (CMUs), are commonly used in basements for their affordability and durability. However, they can look industrial and uninviting. By painting them, you can transform the space into a cozy living area. Follow these easy steps to complete the project.

Steps to Paint Interior Cinder Block Walls
Step 1: Prepare the Walls
Start by wiping down the cinder block walls with a clean, damp towel to remove dirt, dust, and loose paint. If the walls are very dirty, use a multipurpose surface cleaner to spray and clean them.
If there is any flaking paint, use a rubber or metal paint scraper to remove it. Flaked or chipped paint can indicate moisture issues in the cinder block.
Step 2: Apply Sealant
Cinder blocks are porous and can allow water and water vapor to penetrate through. This can cause paint to chip and peel. To prevent this, applying a sealant is essential for a successful paint job on cinder block walls.
Some cinder blocks, especially those in basements, may already have a waterproof sealer. If you’re unsure, it’s recommended to apply a fresh coat of sealant for added protection.
Using a clean paint roller or paintbrush, apply a clear, thin liquid sealant according to the manufacturer’s instructions. Allow it to dry completely before proceeding.
Step 3: Prime the Cinder Blocks
Before painting, it’s important to apply a coat of primer to the cinder block walls. Primer helps fill the porous holes in the blocks, allowing the paint to adhere better and resulting in a more even finish. Choose a primer specifically designed for indoor concrete or masonry use, such as acrylic block fill primer.
Primer is typically white, but you can have it tinted to match your paint color for added depth. Let the primer dry completely, following the drying times specified on the product label.
Apply an even layer of primer using a clean paint roller, ensuring full coverage. Use a paintbrush for corners and hard-to-reach areas.
Step 4: Paint the Cinder Block Walls
Once the cinder block walls are sealed and primed, you can use any type of interior wall paint. There’s no need for specialty paint. Use a clean paint roller to apply two or more thin, even coats of paint until you achieve the desired color, allowing the paint to dry between coats.
