The easiest way to determine if you have a water-based or solvent-based acrylic sealer currently down on your concrete is to run a Xylene test.

To run a Xylene test, saturate a roller with Xylene, or the Armor Blush Repair, and roll over the same 1 FT area for 30-60 seconds until the sealer gets tacky. Once the sealer gets tacky, roll it out and allow it to re-cure.

A few things to keep in mind when doing a Xylene test:

  1. Be sure to keep the roller saturated with Xylene, or the Armor Blush Repair. If the roller dries out, there may not be enough Xylene or Armor Blush Repair to accurately run the Xylene test.
  2. Do not wash the Xylene or Armor Blush Repair off the surface. Roll it out as you would a coating and allow it to remain dry overnight.
  3. Apply the Xylene or Armor Blush Repair in the late afternoon or early evening when air and surface temperatures are declining, and when the surface of the concrete is cool. If you apply the Xylene or Armor Blush Repair in the morning or mid-day, you could end up with bubbles reoccurring in the cured coat.
  4. Do not apply Xylene or Armor Blush Repair to the entire area. Instead, mark off a 1 FT test section in an inconspicuous area.

Once the Xylene test is complete, it’s time to figure out what you have down:

  • Xylene, or Armor Blush Repair, will re-emulsify a solvent based acrylic and turn it into a liquid again. If the Xylene or Armor Blush Repair turned the acrylic into a liquid and it recured looking the same or better, you likely have a solvent-based acrylic sealer down.
  • Xylene and Armor Blush Repair can’t be used to repair a water-based acrylic, in fact, Xylene and Armor Blush Repair will have little to no effect on a water-based acrylic. If the acrylic appears to look rejuvenated but does not become sticky or tacky and eventually returns to a dull or faded appearance, you likely have a water-based acrylic sealer down.
  • If you rolled over the 1-foot area keeping the roller saturated with Xylene or Armor Blush Repair for more than a couple of minutes and the surface did not become noticeably sticky or tacky, then you likely have a water-based acrylic sealer down.
