Using the right tools is critical to achieving the best coverage rate and sealer thickness for optimal performance. The two most common methods of applying sealers to concrete surfaces are by roller or sprayer, often depending on whether the sealer is solvent- or water-based. Always refer to the manufacturer's specific application guidelines.

Whether you are rolling or spray applying a sealer, always strive for maximum coverage. The typical coverage rate is 250 to 300 square feet per gallon, depending on the porosity of the concrete. The most important rule to remember is that less is more. It's best to apply two thin coats, making sure the sealer doesn't puddle or form uneven, thick areas. When applying a second coat of sealer, apply it in the opposite direction (or perpendicular) to the first coat to ensure even coverage. Wait to apply the second coat of sealer for the time recommended by the manufacturer (typically two to four hours).
