Application instructions
- TEST PRODUCT ON A SMALL AREA FIRST and allow a 24-hour cure time to determine the ease of application and desired results.
- Ensure surfaces to be treated are clean, dry, and free of residues.
- Generously and evenly saturate the surface with Water based Penetrating Sealer using a clean paintbrush, roller or lambswool applicator.
- Avoid contact with surrounding areas. Very absorbent surfaces may need a second coat. Apply a second coat while the first coat is still wet.
- Allow the sealer to penetrate for approximately 10 minutes, but before the sealer dries, thoroughly polish 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.
- Total application rate is approximately 1 quart per 40 to 120 SF. or 1 liter per 4 to 12 square meters depending on surface absorption (1 gallon per 160 to 480 SF. or 3.79 L per 16 to 48 sqm).
- Clean equipment with water.
Note: Water based Penetrating Sealer WILL NOT prevent surface etching, scuffing or wear, and may lighten or darken some surfaces.
Other Application Insights
- TESTING Waterbased Penetrating Sealer. The product will reach full cure and should only be tested after 4 to 5 days cure time.
- There is a significant increase in stain repellence when the product is allowed to reach full cure.
- 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 without the sealer becoming visible, but it also takes 1 or 2 days longer to reach full cure than the standard 3 days for a fluorocarbon sealer.
- APPLYING Waterbased Penetrating Sealer ON POLISHED SURFACES.
- Waterbased Penetrating Sealer must be applied to polished surfaces with a lambswool applicator, roller or paint brush, not a sprayer.
- 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.
- APPLYING WATERBASED PENETRATING SEALER TO HIGHLY POROUS SURFACES.
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.
