Custom Mural Process: From First Concept to Final Stroke
A custom mural transforms an ordinary wall into a living story — but what actually happens between your first phone call with an artist and the moment you step back and admire the finished piece? For many clients in Toronto and across Canada, the process feels mysterious. You have a vision, a wall, and a budget, but the steps in between can seem unclear.
The truth is that a great mural is never just paint on a surface. It's weeks of planning, collaboration, and skilled execution. Understanding each phase of the process not only sets realistic expectations — it also helps you become a better creative partner to your artist, which almost always results in a more stunning final result.
At Sanjay Dangi Arts, we've guided homeowners, business owners, schools, and developers through the custom mural journey countless times. Whether you're commissioning a bold exterior mural in downtown Toronto or a delicate hand-painted accent wall in your Etobicoke home, the core process follows the same proven stages. Here's exactly what that journey looks like, from the very first conversation to the final brushstroke.
Stage 1: The Discovery Consultation — Defining Your Vision
Every custom mural begins not with paint, but with a conversation. During the initial discovery consultation, the artist works to understand your goals, aesthetic preferences, the purpose of the space, and any specific imagery, themes, or emotions you want the mural to evoke. This is the most important stage of the entire process — a poorly defined brief leads to costly revisions down the road.
For Toronto-based projects, this consultation often happens on-site so the artist can assess natural lighting, wall texture, surrounding decor, foot traffic patterns, and architectural features that will influence the design. For clients outside the city, video walkthroughs and detailed photo submissions work just as effectively.
Come prepared with inspiration images, colour swatches, and a clear sense of who will experience the space — customers, children, residents, or passersby. The more context you share, the more targeted and powerful the final design will be. A skilled mural artist will also ask about your timeline, any permits required for exterior work in your Toronto neighbourhood, and whether the surface needs special preparation. This upfront clarity saves time and money at every stage that follows.
Stage 2: Concept Development and Mood Board Creation
Once the consultation wraps up, the artist retreats to the studio to translate your ideas into a concrete visual direction. This stage typically involves creating a mood board — a curated collection of colours, textures, artistic styles, and reference images that captures the overall feeling of the proposed mural before a single sketch is made.
The mood board serves as a creative checkpoint. It gives you the opportunity to confirm the direction or redirect it before the artist invests significant time in detailed sketching. In our experience at Sanjay Dangi Arts, clients who engage thoughtfully at the mood board stage almost always end up with a final mural that exceeds their expectations.
After mood board approval, the artist develops initial concept sketches — rough compositional layouts that establish the placement of key elements, focal points, and overall flow of the design. These sketches are intentionally loose at this stage to allow for broad changes without wasted effort. You might receive two or three distinct compositional directions to choose from. Feedback is encouraged and incorporated before moving to the refined digital rendering stage. For complex murals in commercial spaces across the GTA, this stage can take one to two weeks of focused creative work.
Stage 3: Digital Rendering and Final Design Approval
With a chosen concept sketch in hand, the artist creates a detailed digital rendering — a full-colour, to-scale mockup of the mural as it will appear on your specific wall. Modern rendering tools allow the artist to superimpose the design directly onto a photograph of your actual space, giving you an incredibly realistic preview of the finished piece.
This is arguably the most exciting stage for clients. Seeing your ideas rendered in vivid colour at actual scale makes the project feel real and tangible for the first time. It also surfaces any last-minute adjustments — perhaps a colour feels too bold in context, or a figure needs to shift slightly to avoid a light switch or vent.
All revisions are made at the digital stage, where changes are fast and cost-free. Most projects include two rounds of revisions as part of the standard process. Once you sign off on the final digital rendering, it becomes the locked blueprint for the physical mural. This approval document protects both the client and the artist, ensuring complete alignment before any paint is purchased or ladders are set up. For large-scale commercial murals in Toronto, this rendering is also often shared with building managers, architects, or city permit offices for formal approval.
Stage 4: Surface Preparation — The Invisible Foundation
Professional mural artists will tell you that surface preparation is where the longevity of a mural is won or lost — yet it's the stage clients see the least. Before any colour goes on the wall, the surface must be thoroughly cleaned, repaired, and primed. Skipping or rushing this stage is the number one reason murals peel, crack, or fade prematurely.
For interior murals in Toronto homes and businesses, preparation typically involves patching any holes or cracks, sanding rough areas, cleaning away grease or dust, and applying a primer coat suited to the surface material — drywall, plaster, brick, or wood each require different approaches. For exterior murals exposed to Canada's harsh freeze-thaw cycles, this preparation is even more critical. A masonry sealer, anti-efflorescence treatment, and UV-resistant exterior primer may all be necessary.
The type of paint selected also matters enormously. Professional mural artists use high-quality acrylic paints, artist-grade mediums, and specialty exterior coatings designed to resist moisture, UV radiation, and Toronto's dramatic seasonal temperature swings. At Sanjay Dangi Arts, we source professional-grade materials that are certified safe for indoor environments and built to last for decades outdoors with proper care. This preparation phase can take anywhere from one day to several days depending on wall size and condition.
Stage 5: Transferring the Design and Laying the Base
With the surface prepped and primed, it's time to transfer the approved design from screen to wall. Depending on the scale and complexity of the mural, artists use several professional methods to do this accurately. Grid transfer involves dividing both the reference image and the wall into equal sections, then replicating each section by hand — a traditional technique that preserves artistic integrity. Projector transfer uses a digital projector to cast the design directly onto the wall, where the artist traces the main outlines in chalk or light pencil before painting.
Once the outline is established, the artist begins laying in the base colours — large, flat areas of colour that establish the tonal foundation of the piece. This is sometimes called the 'blocking in' stage. It looks surprisingly rough at this point, which can momentarily alarm clients watching the process. Rest assured: this is entirely normal and expected. The detail, depth, and dimension come in subsequent layers.
The base layer is also strategically important because it determines how subsequent colours interact. Warm undertones beneath cool colours create vibrancy; cool undertones beneath warm tones create subtle depth. Experienced mural artists like those at Sanjay Dangi Arts think several layers ahead during this stage, making decisions now that pay off visually in the final piece.
Stage 6: Detail Work, Shading, and Layering
This is the stage where the mural truly comes alive. Once the base is dry, the artist begins the painstaking work of adding shading, highlights, fine details, and texture that give the piece its visual depth and emotional power. Depending on the complexity of the design, this stage can represent 60 to 70 percent of the total painting time.
Layering is the key technical skill at work here. Multiple transparent glazes of colour are built up to create smooth gradients, three-dimensional forms, and realistic textures — whether that's the grain of wood, the softness of foliage, the reflectivity of water, or the subtle skin tones of a portrait. For murals featuring intricate patterns, typography, or photorealistic elements, this stage demands exceptional precision and patience.
For large murals in Toronto's commercial spaces — restaurants, hotels, office lobbies, or community centres — the detail phase often unfolds over several working days with artists working from scaffolding or elevated platforms. Progress photos are shared with clients regularly so you can follow along even if you can't be on-site. At Sanjay Dangi Arts, we believe keeping clients informed throughout this stage builds trust and generates the kind of genuine excitement that turns clients into lifelong advocates.
Stage 7: Finishing, Sealing, and Final Walkthrough
Once the painting is complete and fully dry, the artist applies a protective varnish or sealant coat over the entire mural. This final layer is not optional — it's essential. For interior murals, a clear matte or satin varnish protects the surface from dust, moisture, accidental scuffs, and UV yellowing from indoor lighting. For exterior murals in Toronto, a UV-resistant anti-graffiti coating provides a critical shield against fading, weather damage, and vandalism.
The sealant also unifies the finish across the entire mural, eliminating any inconsistencies in sheen between different paint layers or application techniques. The result is a cohesive, polished surface that looks professional from every angle and distance.
After sealing, the artist conducts a thorough final walkthrough with the client. This is your opportunity to inspect every detail up close, ask questions, and flag anything that doesn't match the approved rendering. Any minor touch-ups are made on the spot. You'll also receive care and maintenance instructions tailored to your specific mural and environment — including how to clean the surface, what products to avoid, and when to consider a fresh topcoat to maintain long-term protection. For Toronto clients with exterior murals, we generally recommend a resealing inspection every three to five years given our climate.
A custom mural is one of the most impactful investments you can make in a home, business, or public space — and understanding the process behind it transforms you from a passive client into an active creative collaborator. From the discovery consultation and mood board all the way through surface preparation, layering, and final sealing, each stage serves a deliberate purpose that contributes to a result built to last.

How long does it take to complete a custom mural?
The timeline depends on the size, complexity, and surface conditions of the project. A small interior mural of roughly 8 by 10 feet typically takes one to two weeks from consultation to completion, while large-scale exterior murals in Toronto can take four to eight weeks or more. The design and approval stages alone usually require one to two weeks before any physical painting begins.
How much does a custom mural cost in Toronto?
Custom mural pricing in Toronto varies widely based on wall size, design complexity, surface preparation requirements, and indoor versus outdoor location. Small residential murals often start around $800 to $1,500, while large commercial or exterior murals can range from $5,000 to $25,000 or more. A detailed quote is provided after the initial consultation once the scope of the project is clearly defined.
Do I need a permit for an exterior mural in Toronto?
In many cases, yes. The City of Toronto requires a sign permit for exterior murals on commercial properties, particularly if the mural is visible from a public street. Requirements vary by neighbourhood, zoning, and mural size. At Sanjay Dangi Arts, we help clients navigate the permit process and can advise on what approvals are needed before the project begins.
How do I prepare my wall before the mural artist arrives?
For most projects, the mural artist handles all necessary surface preparation as part of the service — including patching, priming, and cleaning. As a client, you can help by ensuring the wall area is accessible, free of furniture or obstructions, and that any sensitive nearby surfaces or flooring are pointed out so they can be properly protected. Your artist will confirm any specific prep requirements during the consultation.
