On Monday, Walmart announced that it will stop selling paint strippers containing methylene chloride or N-methylpyrrolidone (NMP) by February 2019 – making it the first general merchandise retailer to take such action. Walmart’s announcement follows the strong leadership demonstrated by Lowes, Home Depot, and Sherwin Williams, all of which have committed not to sell methylene chloride- and NMP-based paint stripping products by the end of the year. Importantly, Walmart’s action goes beyond its U.S. stores, including those in Mexico, Canada, and Central America, as well as its online store.
