Benefits of STAIN PROOF™ Premium

  • Premium water and oil repellence
    for superior stain protection: Tested in accordance with ISO 10545-14
    Determination of Resistance to Stains: Class 5 (highest class).

  • Unique super-penetrating permanent bonding technology for long
    lasting protection. 15 year written performance warranty can be provided
    if applied by a Stain-Proof Accredited Applicator*.
  • Protects against efflorescence, freeze-thaw and salt spalling
    damage. (NOTE: Softer materials, including limestone, sandstone and
    travertine in a freeze-thaw or salt water environment need extra
    protection – use 40SK Consolidator & Water Repellent).
  • Retains natural surface color and finish. Treated surfaces are easier to clean and dry quickly even after heavy rain.
  • Super breathable: Water vapor escapes freely preventing harmful moisture buildup inside the treated material.
  • Stands up to commercial cleaning methods.

How To Use STAIN PROOF™ Premium

Regular Application

INCONSPICUOUS AREA FIRST.Allow a 24-hour cure time to determine the ease
of application and desired results.

  1. Apply when surface temperature is between 40 – 95°F (5-35°C). Avoid
    moisture contact with the surface for six hours after application.
    Surface must be dry, clean and free of residues.
  2. DO NOT thin product.
  3. Generously apply STAIN-PROOF™ Premium Impregnating Sealer using low
    pressure hand sprayer or microfiber applicator. Porous surfaces should
    have a mirror like ‘wet’ look for 3-5 seconds. Avoid contact with
    surrounding areas.
  4. Wait at least 10 minutes (or longer for dense material) and, before
    the surface dries, repeat Step 4. Total application rate is
    approximately one quart per 20 to 250 sq. ft. (one liter per 2 to 25
    sqm), depending on surface absorption. Visit for our
    coverage chart.
  5. After the final coat, wait approximately 10 minutes but, before the
    surface dries, polish the surface thoroughly with clean, dry, white
    terry cloths towels or similar to remove excess product, moistening
    cloth with STAIN-PROOF™ Premium Impregnating Sealer to ease removal.
  6. Use an organic solvent e.g. denatured alcohol or mineral spirits to clean equipmen.

Advanced Application Tips

1. TESTING Premium Impregnating Sealer
Premium Impregnating Sealer must be allowed to cure for at least 3 weeks before undertaking testing.

a. Achieving optimum stain repellence.
Premium Impregnating Sealer’s
specially designed sealing molecules migrate through the pores and find
sites to bond by a process of chemical reaction, over 3 to 4 weeks! As
more Premium Impregnating Sealer molecules bond inside the
pores, the material becomes more oil and water-repellent. After 24 hours
of cure time, the product will show only adequate stain repellency and
zero penetration, but after 3 weeks cure time the results will be
significantly better.

b. Achieving maximum depth of penetration.
The modified silane molecules in Premium Impregnating Sealer
are hundreds of times smaller than the best modern competitor
(fluorocarbon /siloxane) sealers, which cannot penetrate into the pores
of dense materials, such as polished granites. After 3 weeks of cure
time, typical penetration of Premium Impregnating Sealer into Kashmir white granite is 8 to 13 millimeters.

Premium Impregnating Sealer should
be applied to smooth surfaces with a lamb’s wool applicator or cloth,
so the sealer is wiped over the surface. Spraying is not recommended for
polished surfaces. Drying time between coats should be maximized –
approximately 15 minutes.

Highly porous surfaces, such as sandstone and soft varieties of limestone should ideally be pre-sealed with a light spray of Premium Impregnating Sealer,
at least 8 hours before applying the 2 main coats. Apply sufficient
product so the surface looks shiny / mirror wet for at least 3-5 seconds
after each coat.

On a new installation, apply a coat of Premium Impregnating Sealer
prior to grouting. Then 24 hours after the first coat, apply the grout.
After the grout dries (ideally 24 hours later), apply the second coat
of Premium Impregnating Sealer. The first coat of Premium Impregnating Sealer will help reduce the chances of picture framing occuring and make grout haze easier to clean.

vertical surfaces you have much less dwell time than on horizontal
surfaces as a liquid sealer will run down the wall if a substantial
amount is applied. You need plenty of dwell time for the product to
penetrate sufficiently. The way to do this is to apply 4 light coats of Premium Impregnating Sealer
instead of 2 generous coats. Apply each successive coat before the
previous one dries (wet on wet, approxmately 10 minutes between coats).
Place tarp or plastic sheets below to catch the excess drips.

Cover surrounding areas which you do not wish to treat with Premium Impregnating Sealer. Use removable painter’s tape to cover the bottom of walls.


Application Rates

Total application rate is approximately one litre per two to 25 sq. meters (20 to 250 sq. feet per quart) depending on absorption. The table of minimum application rate can be used for your reference. Premium Impregnating Sealer must be allowed to cure for at least 3 weeks before undertaking testing.
