Abstract
Method of preparing a colored self-levelling cementitious floor covering by mixing a colorant with a cementitious floor covering premix used in forming of the colored self-levelling cementitious floor covering. The colorant is a flowable, spray-dried, particulate formulation prepared from a mixture of ingredients in water containing 85 to 95% by weight of one or more inorganic pigments, 3 to 7% by weight of poly(ethylene glycol) having a median molecular weight in the range 7,000 to 9,000, 3 to 6% by weight carboxylated acrylic co-polymer dispersant and 0.5 to 2.0% by weight hydroxylated amine.
Claims4
A method of preparing a coloured self-levelling cementitious floor covering comprising the step of mixing a colourant with a cementitious floor covering premix used in forming of the coloured self-levelling cementitious floor covering where the colourant is a flowable, spray-dried, particulate formulation prepared from a mixture consisting essentially of, as ingredients, 85 to 95% by weight of one or more inorganic pigments, 3 to 7% by weight of poly(ethylene glycol) having a median molecular weight in the range 7,000 to 9,000, 3 to 6% by weight carboxylated acrylic co-polymer dispersant and 0.5 to 2.0% by weight where the formulation is prepared from a mixture of the ingedients in water.
