COMMENTS:

  1. Since maximum allowable weight loss is 0.5%, all brick exceed CSA/CAN A82. 1-M87 and ASTM C216-86 freeze thaw requirements.
  2. Approximately 1% of coating degraded for sample stained at 75% strength, the remaining samples showed no visible signs of coating degradation over the 50 freeze thaw test period.
