ArcusStone & Armourcoat Finishes
High-end architectural coatings
ArcusStone (natural stone look), Armourcoat (polished plaster), Lymestone, and foam columns and trim for upscale residential and commercial.
Our crews bring decades of hands-on experience to every arcusstone & armourcoat project. We work clean, communicate clearly, and deliver finishes that look right and hold up to Bay Area weather.
Every project starts with a careful site walk and a written estimate. We assess substrate condition, surrounding finishes, and any waterproofing or structural prep before the work begins. We handle the entire stack in-house: lath, mesh, scratch coat, brown coat, finish — and any specialty coatings called out by the architect or homeowner.
