St. Astier Natural Hydraulic Lime

St. Astier Natural Hydraulic Lime, or NHL, is a 100% natural product that has been in production since 1851. St. Astier NHL Mortar is widely used in the restoration of old buildings. This natural hydraulic lime mortar imported from France allows stone to "breathe" naturally. Used in construction as plaster, stucco, mortar, and paint, its high level of vapor exchange and mineral composition can help reduce the risk of mold development and dry rot. NHL products are highly permeable, elastic, low shrinking, zero VOC, self-healing, and recyclable. Transmineral USA also offers Le Decor Selection, a line of high-end, all-natural interior/exterior limestone finishes which require trained installers and crushed limestone aggregate imported from France instead of the domestically available aggregate used for the St. Astier NHL products.
