Wood protector aerosols recalled over propellant leakage concerns

US-based Thompson’s Company has recalled its WaterSeal waterproofing wood protector and masonry protector aerosol cans over concerns that the contents may react with the product, causing propellant leakage.

The manufacturers believe the reaction could cause rust to form along the seam of the can, which could spread to other areas of the can and create small leaks. Leaking aerosol propellant poses a fire risk.

Thompson’s WaterSeal waterproofing wood and masonry protector aerosols are designed to coat exterior wood to prevent water damage. The recalled cans are 11 ounces (311g) and have a green or blue cap. Consumers have been advised to immediately stop using the product and to discard it in accordance with local requirements. Thompson’s Company is also offering customers a refund.
