Common Questions About Grout Safety

CAUTION

Is it safe to use grout after the expiration date?

Grout past its labeled date may still function but could have reduced effectiveness. The manufacturer's date indicates guaranteed performance. After this date, the product may separate, lose potency, or not perform as expected. Check for changes in color, consistency, or smell before use.

CAUTION

What if grout looks different than when purchased?

Changes in color, consistency, or separation in grout typically indicate the product has degraded. While this may not pose a safety hazard for non-food items, it usually means reduced effectiveness. If the product has solidified, separated significantly, or changed color dramatically, it is best to replace it.
