How Do You Apply SureCrete XS-327 urethane water-based Countertop Protection?

Following these instructions, anyone can apply XS-327 sealer countertops:

  1. Any surface that is about to be sealed needs to be completely cured, clean and free of all contaminants, and fully profiled and etched.
  2. Mix 2 parts B and 3 parts A continuously for 3 minutes to ensure complete catalyzation.
  3. For the prime coat, add 7 parts water to 1 part catalyzed product and mechanically mix for 2 minutes.
  4. Flood surface with xs-327 concrete countertop sealer and work into the surface using a high-density foam roller until the surface is saturated.
  5. Backroll the surface with a relatively dry roller using only the weight of the roller.
  6. Once the prime coat is dry to the touch, the surface is ready for the first coat.
  7. After mixing another batch to full catalyzation, dilute catalyzed product at a rate of 2 parts water to 1 part sealer.
  8. Apply XS-327 again in similar fashion as a prime coat, this time with only an even coating, again back rolling to prevent roller marks.
  9. Once the first coat is dry to the touch, the surface is ready for the second and final coat of sealer.

  11. Apply countertop sealer in similar fashion to first coat with an even coating and again back rolling to prevent roller marks.

Frequently Asked Questions About XS-327:

Question: Is XS-327 counter topping food safe?

Answer: After the full cure is achieved in 7 days, sealed surface is completely finish food safe.

Answer: Although our sealer was designed for concrete surfaces, we have had wood finishers use 327 with success.

Question: How long do I have to wait between coats?

Answer: Only until the sealed surface is dry to the touch and not tacky. If allowed to sit more than 12 hours, the surface will need to be sanded with 220 grit sand paper to ensure proper adhesion.

Question: Do I need to use multiple coats XS-327?

Answer: Yes, the prime coat is essential for good penetration of the sealer and it is much easier to apply at dilution rates of 2:1 and 1:1. “Straight-up” application is never suggested.
