Stone Veneer Mortar is a high performance, polymer-modified mortar designed to set and grout artificial stone and natural stone veneers. Adding stone veneer to a wall, fireplace, or column can add unique style to your home. While stone veneer is not designed to be load-bearing, it can be used over nearly any solid wall including masonry units, poured concrete, or plywood. A quality stone mortar mix or brick mortar mix is imperative to ensuring your masonry project is completed with the utmost care.
