The Flood brand's rich heritage provides the backbone for the innovative technology found inside each superior wood care and paint additive product. Founded in 1841 by a family of professional painters, Flood is a leading producer of specialty wood stain and paint additive solutions for consumer, commercial and industrial applications. The initial Flood offering, Penetrol® paint additive, was such a breakthrough that it's still sold today and is a key component in many Flood brand exterior wood stain products.
