PhotoThe Thompson’s Company of Cleveland, Ohio, is recalling about 850,000 cans of Thompson’s WaterSeal Waterproofing Wood Protector and Masonry Protector.

The contents of the cans can react with the package, causing rust to form along the can seam, which could spread to other areas of the can and create pinhole leaks.

Leaking propellant poses a fire hazard when it comes into contact with sources of ignition, and can also result in property damage.

The firm has received approximately 18 reports of leaking cans from retailers. No injuries, fires or property damage were reported.

This recall involves Thompson’s WaterSeal waterproofing wood and masonry protectors in aerosol cans. The products are used to coat exterior wood to prevent water damage.

The aerosol cans are 11 ounces and have a green or blue cap. “Thompson’s WaterSeal,” “Wood Protector” or “Masonry Protector,” the item number and UPC code are printed on the can.
