Porter's Original Lime Wash is a unique lime based coating blended with natural pigments that creates a soft weathered patina reminiscent of the wonderful finishes on the building of Tuscany, Portofino and other regions throughout the Mediterranean. Porter's uses slaked and aged lime that gives this finish its ageless beauty. It is a truly wonderful traditional material that mellows gradually while it wears away. Lime Wash also has hygienic properties and acts a mild fungicide due to its high PH. This product contains 0g/L VOC. The APAS target level for this product is 70g/L. (APAS is the Australian Paint Approval Scheme).
