Avg. Rating:

For a versatile primer that's excellent for stain-blocking, adhesion and sealing Interior/Exterior surfaces, choose BEHR Multi-Surface Stain-Blocking Primer & Sealer. This 100% styrene acrylic formula resists medium to heavy stains, and can even be used on metal, aluminum and to cover old oil-based paint. It's also tintable, so it's great when you're looking to make a colour change. This is also a low odor, low VOC formula.
