Limestone Plaster Stonecoat

Stonecoat™ is a field-applied limestone coating consisting of a proprietary mix of quarried, crushed limestone, select polymers and Portland cement for added strength. The product is hand-tooled on vertical or horizontal surfaces to produce the look of cut stone finishes, complete with grout lines. Stonecoat™ can also be used to create beautifully durable countertops, dramatic fireplaces, door and window surrounds, custom columns, arches, quoins, flooring, wainscoting, and numerous other decorative stone elements.

Stonecoat is installed exclusively by trained applicators, and can be textured, honed and finished like cut stone, or given the look of a more rustic field stone. The coating can be either hand-troweled or spray-applied to a variety of substrates including Portland cement, cement plaster (stucco), gypsum board, poured-in-place concrete, CMU blocks, brick masonry, cement backer boards, lightweight concrete, ceramic or natural stone tile, and EPS foam.

The range of aesthetic objectives that can be realized with Stonecoat is virtually limitless — from elegant and authentic, to modern and organic. Whether it be a luxury residence, resort, commercial project, architectural features such as fireplaces, range hoods, counter tops, pool copings, fountains, etc., interior or exterior wall surfaces, adding a decorative Stonecoat finish can enhance the appearance of any architectural design.

Additional Advantages of Stonecoat Finishes

Beyond its visual appeal, Stonecoat offers several long-term benefits that make it a preferred choice among architects, builders, and property owners seeking a durable and customizable surface treatment. Its cement-based composition forms a strong bond with a wide range of substrates, helping protect exterior walls from moisture, temperature fluctuations, and general wear caused by exposure to the elements. Because Stonecoat can be applied in various thicknesses and textures, it allows designers to create distinctive finishes that replicate everything from hand-carved limestone to smooth, modern wall surfaces.

Stonecoat is also valued for its versatility in both residential and commercial settings. Whether enhancing a contemporary home, restoring a historical building, or adding character to an outdoor living space, this coating provides a cost-effective alternative to natural stone without sacrificing aesthetic authenticity. When properly applied and maintained, Stonecoat finishes can retain their color, texture, and performance for many years, making them an ideal solution for property owners who want longevity without the maintenance demands of traditional masonry materials.
