Application & Installation


  1. ALWAYS TEST the product on a small hidden area of approximately 4 sq. ft. (0.4 sq. m.) to ensure the results will meet your expectations.
  2. Remove all the stains from the natural stones, using Flexlock Clean products. Use Gator Clean Sealer Stripper to remove any unknown coating that remains on the natural stone surface.
  3. Remove all contaminated jointing material and replace with Flexlock Polymeric Sand. Follow the instructions on the back of the bags for proper sand installation.
  4. Wait at least 48 hours at a minimum temperature of 40°F (4°C) and no rain for the Flexlock Polymeric Sand to properly harden.
  5. Clean the entire surface with the Flexlock Efflorescence Cleaner. This product will remove the efflorescence trapped in the natural stone pores as well as thoroughly clean the surface for proper sealer adhesion.
  6. Wait at least 48 hours at a minimum temperature of 40°F (4°C) and no rain so the sand & natural stone surface are dry.
  7. Best Practice: (See online video. 2 people needed.) Apply one (1) coat of Ultra Series Natural Stone Sealer using a sprayer in 60 sq. ft. sections, then use a solvent-resistant foam roller to remove the excess sealer left on the surface.
  8. Ultra Series Natural Stone Sealer is water repellant, rain safe, after 24 hours.
  9. Let the sealer dry for 24 hours before using the sealed area.


  1. Natural stones should only be sealed 60 days after their installation date. Consult natural stone manufacturer’s for their recommendation.
  2. Natural stones and jointing sand MUST be 100% dry.
  3. Temperature should be between 40°F (4°C) and 85°F (29°C) when sealer is applied.
  4. Natural stone surface must be cool to the touch when sealer is applied (between 40°F (4°C) and 85°F (29°C)).
  5. First clean natural stones with Flexlock Clean products. Remove all oil, grease and rust stains.
  6. Use Flexlock Efflorescence Cleaner to remove any trapped efflorescence. It also thoroughly cleans the surface to ensure a proper sealer adhesion.
  7. Use just one (1) layer of sealer.
  8. When using Ultra Series Natural Stone Sealer, assure yourself at least 48 hours of dry conditions prior to applying the sealer.
  9. Specifically formulated to be used on unsealed surfaces only. Cannot be used as a resealer.
