Arcus Stonecoat

Arcus Stonecoat

Arcus 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. 

Arcus 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.

Arcus 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 Arcus 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 Arcus Stonecoat finish can enhance the appearance of any architectural design.

Arcus Stonecoat continues to be appreciated for its ability to support a wide range of architectural goals. Because the finish is applied on-site, it can be adapted to curved profiles, detailed trim, or irregular shapes without needing factory-cut components. This makes it suitable for both new construction and renovation work where surfaces may require refinishing rather than full replacement.

Designers often use Arcus Stonecoat to highlight feature areas such as accent walls, archways, or detailed mouldings, allowing these elements to blend with surrounding materials while still offering visual depth and interest. The product’s handcrafted character contributes to projects seeking a refined, stone-inspired look without the complexity of working with quarried stone. When installed by trained applicators, Arcus Stonecoat provides a dependable finish that maintains its appearance and supports long-term design continuity, helping unify interior and exterior spaces. Its adaptability makes it a practical option for projects with unique requirements or evolving design themes.
