Is Glidden paint made by Sherwin Williams?

No, Glidden paint is not made by Sherwin-Williams; it is made by PPG Industries, which is one of Sherwin-Williams' largest competitors. This confusion is common because the paint industry has consolidated significantly. Glidden was founded in 1875 in Cleveland, Ohio, and was independently owned for many years before being acquired by ICI Paints, then by AkzoNobel, and finally by PPG in 2013 when PPG bought AkzoNobel's North American architectural coatings business for $1.05 billion. Since then, Glidden has been a core brand in PPG's portfolio alongside PPG Paints, Olympic, and Dulux in Canada. Sherwin-Williams, on the other hand, owns Valspar, HGTV Home by Sherwin-Williams, Minwax, Krylon, and its own Sherwin-Williams branded paints sold in Sherwin-Williams stores and at Lowe's. The two companies operate completely separate manufacturing plants, research labs, and distribution networks. PPG manufactures Glidden primarily in its plants in the United States, such as in Huron, Ohio and other facilities, while Sherwin-Williams manufactures Valspar and its own brands in its own plants. So when you buy Glidden at Home Depot or Walmart, you are buying a PPG product, not a Sherwin-Williams product.
