Troubleshooting Acrylic Sealers: Whiting

Cause: Moisture Entrapment. Moisture entrapment occurs when moisture is left in, or is evaporating out of concrete substrate or if moisture accumulates on a sealer application prior to completing full cure. Solution: Whiting is easily resolved with an application of an acceptable solvent (check your local VOC Regulations to help maintain proper VOC levels). Scrub the affected sealer application vigorously to re-emulsify the sealer and allow for proper ventilation. It may be necessary to repeat this step to fully remove any remaining moisture. Upon curing the whiting should disappear.
