An acrylic paint specifically made for masonry and exterior surfaces is the best for painting cinder blocks. It is water-based and provides a durable finish that can withstand the demands of exterior conditions. A masonry bonding and filling primer should be used before painting to provide a smoother finish.

If painting exterior surfaces like a cinder block fence or shed, be sure to use an exterior grade 100% acrylic paint made for outdoor conditions. For cinder blocks in moisture-prone areas like basements, consider an elastomeric masonry paint.

The best types of paint for your cinder blocks are going to be acrylic latex paint and elastomeric paint. You can also go with milk paint if you’re looking for an option without any volatile organic compounds (VOCs). Be sure to buy interior or exterior concrete paint depending on if you’ll be painting indoors or outdoors.

Choose the Right Paint: Select a paint that is suitable for exterior use if the cinder blocks are located outdoors. Acrylic latex paint is ideal because it’s durable and resistant to weathering. Apply at least two coats for optimal coverage, allowing the paint to dry between coats.
