How To Use

  1. TEST PRODUCT ON A SMALL AREA FIRST and allow a 24-hour cure time to determine the ease of application and desired results.

  2. Apply when surface temperature is between 40 - 95°F (5 - 35°C). Ensure surfaces to be treated are clean, dry and free of residues.
  3. Generously and evenly saturate the surface with Stain-Proof™ Waterbased Penetrating Sealer using a lamb’s wool applicator, low-pressure pump sprayer, roller or a paint brush for small cut in areas. Avoid contact with surrounding areas. Very absorbent surfaces may need a second coat. Apply a second coat while the first coat is still wet.
  4. Allow the sealer to penetrate for approximately 10 minutes, but before the sealer dries, thoroughly wipe off all excess from the surface with clean, dry, white cloths/towels. When sealing a large area, work in smaller sections so the excess can be easily removed before it dries.
  5. Total application rate is approximately 1 quart per 40 to 120 sq.ft. or 1 liter per 4 to 12 sqm (1 gallon per 160 to 480 sq.ft. or 3.79 L per 16 to 48 sqm) depending on surface absorption. Avoid moisture contact with the surface for six hours after application.
  6. Clean equipment with water.

Note: Stain-Proof™ Waterbased Penetrating Sealer will not prevent etching from acidic liquids, or surface wear and may lighten or darken some surfaces. Clean sealed surfaces only with a pH balanced stone cleaner such as Stain-Proof™ Countertop or Floor Cleaner. Harsh chemicals, including bleach, will break down sealer.

Advanced Tips

The product will reach full cure and should only be tested after 4 to 5 days cure time.
a. There is a significant increase in stain repellence when the product is allowed to reach full cure.
b. Waterbased Penetrating Sealer is a highly modified fluorocarbon sealer – the molecules are approximately 3 to 4 times smaller than a typical fluorocarbon sealer, and free of cancer-causing PFOAs. This means you can have a higher percentage of active content but it also takes 1 or 2 days longer to reach full cure than the standard 3 days for a fluorocarbon sealer.

a. Waterbased Penetrating Sealer must be applied to polished surfaces with a lamb’s wool applicator, roller or paint brush, not a sprayer.
b. Waterbased Penetrating Sealer tends to pool / bead quickly on polished surfaces, which means it does not have enough dwell time on the surface. To ensure longer contact with the polished surface:
1) Use your applicator / cloth / roller to wipe the sealer across the surface,
2) allow 3 or 4 minutes dwell time, then
3) spread it over the surfaces AGAIN and
4) allow a further 5 to 10 minutes of dwell time before polishing off all excess product.

a. Highly porous surfaces, such as sandstone and the more porous types of limestone may require 2 coats. It is important to apply the second coat while the first coat is still a little damp. If the first coat has dried too much, it will start to repel the second coat and prevent it from penetrating and adhering.


WARNING: Causes eye irritation. PRECAUTIONS: Do not handle until all safety precautions have been read and understood. Wear eye protection/face protection. Keep container tightly closed. KEEP OUT OF REACH OF CHILDREN.


Store in a well ventilated place and locked up. Keep container tightly closed.  IN CASE OF Fire: Use alcohol resistant foam or normal protein foam for extinction.


First Aid
