Application and Installation:

For Natural Stones:

  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 Gator 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 Gator 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 Gator Polymeric Sand to properly harden.
  5. Clean the entire surface with the Gator 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. Dry surface for 24-72 hrs prior to apply sealer. Apply one (1) coat of Signature Series Natural Stone Sealer using a sprayer (HVLP), nap roller (5-10 mm), squeegee, sponge or rag. Apply in 60 sq. ft. (5.6 sq. m.) sections at a time. Use a foam roller or squeegee to remove excess sealer from the surface. Allow remaining sealer to penetrate 5-10 minutes. Wipe and remove any excess sealer with clean, dry, lint-free cotton cloths. Repeat after 30 minutes if not well sealed (make the test with a drop of water).
  8. Signature Series Natural Stone Sealer is water repellant, rain safe, after 24 hours.
  9. Let the sealer dry for 8hrs for foot traffic (keep surface dry). Full cure after 72 hrs.

Please Note:

  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 Gator Clean products. Remove all oil, grease and rust stains.
  6. Use Gator 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 Signature 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.
  10. Wear protective gloves, eye protection and respiratory protection.
  11. Always keep surfaces dry and clean to reduce slip-fall accidents. This sealer is not anti-slip. Precautions should be taken around pools and showers.
  12. Do not let it dry (white film or slippery residue may form). If not wiped dry after 5-10 minutes, residue may form. Do not pressure-wash. Not resistant from acids or caustic chemicals. Do not dilute. Not for food handling surfaces. Not for glazed tile or non-porous surfaces. Apply between 70-85°F. Dry residue after a long period may be removed by adding more sealer or mechanically.
