What paint to use on concrete surfaces such as foundations, stucco, or masonry?
Spaces prone to dampness: Behr Dry Plus is a waterproofing paint that helps with any moisture issues. It can resist up to 12 PSI of water pressure. This paint is perfect for a basement that is underground for example.
Exterior applications: Behr Masonry, Stucco and Brick paint is excellent for exterior applications where waterproofing under pressure isn't needed. It has excellent hide, coverage, adhesion and water repellency. 
Uneven surfaces: Behr Elastomeric Masonry, Stucco and Brick Paint. This product is mostly used to even out a surface. It will fill in hairline cracks, but it won't perform miracles. You'll still need to patch anything larger.
