How do I properly prepare the 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 or Concrete/Masonry Cleaner). Apply the cleaners according to the package instructions. After cleaning, rinse the surface with water and allow to dry completely. All old coatings must be removed prior to applying any SEAL-ONCE products. Once the surface has been cleaned and the old coating has been removed, SEAL-ONCE products can be applied, according to the package instructions.
