Transform your ordinary breeze block wall by refinishing it with the proper paint. Before you get started, consider that breeze blocks are composed of an aggregate of fine sand, gravel and ash. These materials are ill-suited for adhesion and will reject new finishes unless you properly condition them. If you want paint to stick to your breeze block walls, treat them with a bonding primer or flaking will eventually result.
