An artisan studio devoted to lime plasters, microcement, and decorative finishes — handcrafted in Ottawa and Toronto, applied across Canada.
Designer Wall Finishes was founded by Robbie Mansour, who fell in love with Venetian Plaster in 2013 shortly after starting his eco-friendly painting business in Ottawa. What began as a single curious sample wall has grown into an artisan studio specializing in interior wall and ceiling finishes — Italian lime plasters, microcement, limewash, liquid metal, and bespoke decorative effects.
We work where our clients are. Our home base is in Ottawa, with an active operation in Toronto and the GTA, and we travel regularly for projects in Montréal, Calgary, Vancouver, Halifax, and beyond.
Every project, regardless of scale or location, is handcrafted with the same patient, layered technique we apply to our own showroom walls.
Internationally trained artisans offering on-site application and online consultations.
We meet on-site or remotely to understand your space, light, and vision. We bring physical samples so you can see and feel the options.
Custom sample boards in your chosen colours and techniques — applied with the actual plaster so you see the true finished surface.
Walls cleaned, primed, and protected. Floors and furnishings shielded. Quiet, clean, careful work — even in occupied homes.
Multiple thin layers applied by hand with steel trowels. Each layer dries, is sanded where needed, and built upon for depth.
The final layer is burnished to your desired sheen and sealed with a protective wax or natural sealant — tailored to the room's use.
You receive care instructions and a finish that's authentically crafted — not a manufactured imitation. Built to last decades.
Every project begins with a conversation. Share your vision and we'll guide you to the perfect finish — Venetian Plaster, Limewash, Microcement, or Liquid Metal.
