Porter's Mineral Paint is a premium silicate paint providing unparalleled colourfastness and durability. Designed to be painted onto render and other unpainted masonry surfaces, Mineral Paint penetrates and chemically reacts with the substrate to "petrify", creating a very strong bond to the substrate, and cannot crack, peel or flake. Guaranteed for 25 years, with an expected life span of 30 years plus, this finish truly is the "Rolls Royce" of exterior paints. This product contains 14g/L VOC. The APAS target level for this product is 70g/L. (APAS is the Australian Paint Approval Scheme).
