How to Apply Siloxa-Tek 8500 Ultra Concentrate Concrete Sealer

Step by step application instructions detailing how to apply Siloxa-Tek 8500 ultra concentrated concrete sealer.

Siloxa-Tek 8500 concrete sealer is available in a ready to use gallon or an ultra concentrated gallon. The ready to use gallon is NOT mixed with water. The ultra concentrated gallon is mixed with 4 gallons of distilled water.

  1. Make sure new concrete has been cured for 28 days
  2. Properly clean the concrete and make sure its dry
  3. If a previous sealer was used, remove it or make sure it has worn away
  4. Tools: 3/8” nap paint roller, sprayer, and/or paint brush
  5. Application temperature: 40F-95F
  6. Pour the 1 gallon of Siloxa-Tek 8500 concentrate into a 5 gallon bucket
  7. Also add 4 gallons of distilled water into the 5 gallon bucket
  8. Stir/mix well
  9. Pour into a sprayer or paint tray
  10. Apply one thin, even coat to an area of about 100 square feet or less.
  11. Immediately go back and apply a second coat while the first coat is still wet

You can walk on the first coat of the Siloxa-Tek 8500 while it is still wet to apply the second coat. A wet-on-wet application technique is used to drive penetration of the sealer into the concrete.

  1. Let the sealer dry for 6 hours before walking, 24 hours before allowing vehicle traffic and protect from rain for 24 hours.
