How do I properly prepare my surface for the application of SEAL-ONCE products?

Ensure all surfaces have been properly cleaned by using the appropriate SEAL-ONCE® cleaner (All Wood Cleaner, Concrete/Masonry Cleaner or ReNew Concrete). Apply the cleaners according to the package instructions. After cleaning, rinse the surface with water and allow to dry completely. If the surface has been coated or sealed previously with another product, that product must be removed prior to applying any SEAL-ONCE products. The old coating can be removed by stripping, sanding or power washing the surface. Once the surface has been cleaned and the old coating has been removed, SEAL-ONCE NANO GUARDTM, NANO GUARD PLUS POLY or ACRYLIC POLY can be applied according to package instructions.
