United States Gypsum Company plant at Plaster City, California

United States Gypsum Company made plaster at Plaster City, California, according to its own sworn answers in lawsuits in 1986 and 1988.^1,2 The 1986 answers name three basecoat plasters with Plaster City as the manufacturing location: Red Top Wood Fiber Plaster - Regular, first produced in 1945 and last produced in 1960; Red Top Wood Fiber Plaster - Machine Application, 1959 to 1961; and Red Top Structo-Lite Gypsum Plaster for Machine Application, 1958 to 1962.¹ The 1988 answers give the same years, though the name of the first product is cut off on the page.²

A 1990 EPA notice that published what U.S. Gypsum reported names Plaster City as a plant for Red Top Firecode "V" Plaster, which it says was made "1962 to 1969 at 16 plants"; the years are for all those plants, not Plaster City alone.³ The same notice calls Firecode D & V a "fireproofing plaster."³
