Sherwin-Williams Faces False Advertising Suit Over Firetex Coating Claims

Sherwin-Williams, the paint giant, has been ordered to face claims that its Firetex coating is falsely advertised as providing substantial fire resistance in fewer coats than rival brands' products. A Missouri federal judge ruled on August 6, 2026, that Sherwin-Williams' marketing was not mere puffery and allowed a competitor's suit to proceed.

The lawsuit alleges that Sherwin-Williams' claims led to a slump in sales for the plaintiff, Co.'s Fireproof product. The judge found that the defendant's advertising could be considered deceptive and misleading, warranting further investigation.

While the ruling is a setback for Sherwin-Williams, it remains unclear what specific actions will result from the lawsuit. The company has yet to comment on the matter, and no details have been released regarding potential damages or settlements.
