Abstract
The present invention is directed to a water-based paint composition for concrete and masonry surfaces, a method of coating a concrete or masonry surface, and a corresponding method of preparing a coated concrete or masonry surface. The paint composition includes about 10-50% by weight water, about 5-40% by weight colloidal silica particles, about 40-85% by weight of an inorganic pigment, and about 1-10% by weight of a polymer binder. The paint composition provides the coated surfaces with excellent resistance to a wide variety of weather conditions, and alleviates health and safety concerns associated with long-term exposure to conventional organic-based paints.
Claims15
A method of coating a concrete or masonry surface, comprising the steps of:
- providing a water-based paint composition comprising water, colloidal silica particles, an inorganic pigment, an anti-fungal ingredient, and 1 to 9% by weight of a polymer binder;
- applying the water-based paint composition to a concrete or masonry surface;
- and
- evaporating the water from paint composition;
- wherein a sum total of all organic components, including, the polymer binder, does not exceed 9% by weight of the paint composition, and the organic components consist essentially of the polymer binder and an optional thickening agent.
A method of preparing a coated concrete or masonry surface, comprising the steps of:
- providing a concrete or masonry surface;
- providing a water-based paint composition comprising about 10-50% by weight water, about 5-40% by weight colloidal silica particles, about 40-85% by weight of an inorganic pigment, an anti-fungal ingredient, and 1-9% by weight of a polymer binder;
- applying the water-based paint composition to the concrete or masonry surface;
- and
- evaporating the water from the paint composition;
- wherein a sum total of all organic components, including the polymer binder does not exceed 9% by weight of the paint composition, and the organic components consist essentially of the polymer binder and an optional thickening agent.
A method of preparing a coated concrete or masonry surface, comprising the steps of:
- providing a concrete or masonry surface;
- coating the concrete or masonry surface with a water-based paint composition comprising water, solloidal silica particles, an inorganic pigment, anti-fungal ingredient, and 1-9% by weight of a styrene-acrylate polymer binder;
- and
- evaporating water from the paint composition to dry the paint composition;
- wherein a sum total of all organic components, including the polymer binder, does not exceed 9% by weight of the paint composition, and the organic components consist essentially of the polymer binder and an optional thickening agent.
