Always test GBS Penetrating Sealer in a small inconspicuous location first. FOUR Surface Requirements BEFORE Applying:
1) Porous
2) Clean
3) Dry
4) Neutral pH
Porous means it should be able to soak in. If there are sealers or adhesives on the surface they will disallow absorption. If the surface has been highly power-troweled it will also make the surface so dense that water will not soak in easily.
How to Test? Place a few drops of water onto the surface and see if it beads up or soaks in. If it soaks in, then the surface is porous and GBS Penetrating Sealer will also soak in. Nothing need be done except to make sure it is clean, dry and have a neutral pH. See #2 and #3 below.
If, however it beads up and does not soak in for about an hour, then there is either something on the surface or it has been power-troweled.
If powertroweled, use our GBS MicroEtch product to open the pores without toxic chemicals. Do NOT acid etch. Or you can grind with a surface grinder that can be rented from most rental stores. If there is latex paint, adhesives, or other acrylic sealers on the surface we recommend our GBS Industrial Strength Cleaner (If it is unknown what type of sealer was used, we recommend purchasing a test sample of the cleaner as some sealers cannot be chemically removed). If efflorescence (white powder), rust stains, red clay stains appear on the surface, use a non-toxic acidic cleaner (Outdoor use only). II - CLEAN Clean means washed with a neutral pH detergent and then dried thoroughly. Ideally use a 3000 psi pressure washer. If you are indoors, this may be difficult so use a damp mop instead. If you have used a cleaner mentioned above or any other strong cleaner you should wash at least twice and rinse at least three times. Then dry well for several days. III - DRY After cleaning, use fans, heat, open windows or a shop vac to remove all water. If there is any water inside the concrete, it will prevent the sealer from soaking in. If it's humid, cold or damp, this could take longer to dry out. Be patient. Even if it appears dry on the surface, moisture may still be inside the concrete. Use a moisture meter to test or wait at least two days during warm weather or three days during cool weather. NOTE: New concrete, even though appearing dry, is still very wet inside. Therefore, you should wait a minimum of 3-4 weeks until it has dried inside. This can be accelerated with heat, fans and good ventilation. IV - NEUTRAL pH New concrete has a high pH. For GBS Penetrating Sealer to work properly, the concrete needs to be in the pH 7-9 range to work well. No higher, no lower. We provide litmus paper so you can test in several areas. Be sure to use distilled water with the litmus test. What to do if the pH is still high after testing? Concrete less than one year old is often still high in pH. If so, you can use our GBS pH Reducer. This will bring the pH down to acceptable levels with a few hours. Then it should be washed off as explained in #2 above. Note: If you need to open the pores due to power troweled surface then our GBS Micro Etch product is sufficient. You don't need both products. - OTHER LIMITATIONS - Apply in good weather when air and surface temperature are above 45°F. and surface temperature is at least 5°F. above the Dew Point. For optimum application properties, materials should be between 70-90°F prior to application. Maintain unused material in closed containers in protected storage at 40-90°F out of direct sunlight. GBS Penetrating Gloss Sealer is not intended to be used submerged in water for an extended period of time. GBS Penetrating Gloss Sealer will not work in conjunction with thinset. The sealer seals the pores of the concrete, thus not leaving anything for the thinset to bond to. GBS Penetrating Gloss Sealer will not work for garages or driveways due to hot tire pick-up. If the surface does NOT absorb water, then there is possibly another sealer applied to the surface and GBS Penetrating Sealer should not be applied.

Spray

Warmer than 55°F

Surface should be Clean, Dry, Neutral pH, Absorbant. Test BEFORE applying. Power-troweled surfaces may not absorb well and should be etched with Micro-Etch.
1. Use a low pressure sprayer (Hudson type) or any sprayer operated at no more than 20 psi. Spray on with low pressure sprayer and back roll any puddles into a dry area with a low nap paint roller. The goal is to saturate the surface with ONE COAT. Note: If concrete was power troweled, then penetration could be much slower. GBS Penetrating Gloss Sealer covers approximately 200 square feet per gallon depending upon porosity.
2. Ideally you will work with two people. One spraying and one using paint roller to spread out excess. Clean roller or brush with soap and water.
3. Allow 48 hours before walking on.
4. Do not use on driveways due to hot tire pick-up. Use of GBS Penetrating Sealer instead. Not recommended for submerged areas in pools or ponds. Do not use outdoors before it rains (within 24 hours). The normal cure time is 48 hours or longer depending upon humidity and temperature. 5. NOT recommended for use prior to painting. Use the regular GBS Penetrating Sealer if you wish to paint over. Note1: GBS Penetrating Gloss Sealer will not harm glass, aluminum, metal, plants, or aquatic life. If GBS Penetrating Gloss Sealer gets on glass, rinse off so it doesn't dry. Note2: GBS Penetrating Gloss Sealer will make the surface smoother and easier to clean but it can become slippery if wet.
