Planning a custom wall mural for your home or business? Discover how long professional mural painting takes, what happens during each stage, and how to plan your project from the initial design to the finished artwork.
A custom wall mural can completely transform a space, turning an ordinary surface into an original piece of artwork.
Whether you're imagining a colourful graffiti mural in a restaurant, an elegant botanical painting in your living room, a whimsical nursery illustration, or a large outdoor mural, one of the first questions you're likely to ask is:
How long does it take to paint a mural?
The answer depends on much more than the size of the wall.
A simple geometric mural might be completed within a day or two, while an elaborate realistic painting could require several days or weeks of careful work.
And the actual painting is only one part of the process.
Before an artist begins applying paint, there may be consultations, design sketches, digital mockups, revisions, wall preparation, and material selection.
Understanding this timeline is particularly important when a mural is part of a home renovation, nursery preparation, restaurant opening, or commercial interior design project.
In this guide, we'll explain how long different types of murals typically take, what influences the schedule, and how you can prepare your space to ensure the process runs smoothly.
1. How Long Does It Take to Paint a Wall Mural?
A professional mural can take anywhere from a single painting day to several weeks or longer, depending on its complexity and scale.
For most residential feature walls, the actual painting may take approximately two to five working days, although simpler designs can be faster and highly detailed work can take considerably longer.
Large commercial and outdoor murals often require more extensive schedules.

These are approximate working-time examples, not guaranteed completion times. The total project schedule may be longer because of design development, preparation, approvals, drying requirements, and artist availability.
For example, a relatively simple 8-by-10-foot abstract mural could be completed faster than a highly detailed portrait measuring just 5 by 7 feet.
The smaller portrait may require more precise drawing, colour blending, and detailed brushwork.
This is why mural artists generally consider both the dimensions and artistic complexity when estimating a project's duration.
2. The Mural Design Process: What Happens Before Painting?
One of the most overlooked parts of a mural commission is the design stage.
Clients sometimes assume that once they've chosen an artist, painting can begin immediately.
In reality, custom artwork usually requires planning.
The amount of design preparation depends on whether the client already has a clear idea or needs an entirely original concept developed.
Initial consultation
The process typically begins with discussing the proposed mural.
The artist may ask about the wall's dimensions, location, preferred artistic style, colour palette, budget, and desired completion date.
Reference photographs and inspiration images can help communicate the direction you're looking for.
An initial consultation may be relatively brief for a straightforward project.
For an elaborate commercial commission, more detailed discussions may be necessary.
Concept development
Once the artist understands the project, they begin developing the composition.
This may involve sketches, digital drawings, colour studies, and reference research.
For example, a nursery mural featuring animals, mountains, and an illustrated world map requires planning to ensure the different elements work together.
Similarly, a restaurant mural incorporating graffiti lettering, portraits, and architectural references needs a cohesive overall design.
Digital mockups
For some projects, the artist may place a proposed design onto a photograph of the actual wall.
This helps the client visualise how the completed artwork will appear.
It's particularly useful when the mural needs to work around windows, doors, furniture, or architectural features.
Design revisions
Clients may request adjustments before the artwork is approved.
These might involve changing colours, moving elements, simplifying details, or altering the overall composition.
The number and complexity of revisions can influence the schedule.
Typical planning consideration: Allow several days to a few weeks for design development, depending on the project, revision process, and the artist's workload.
A clear design approval process helps prevent delays once painting begins.
3. Wall Preparation: Why It Matters for the Timeline
Before painting can begin, the wall must be suitable for the artwork.
This step may be relatively straightforward for a clean, previously painted interior wall.
However, damaged or unsuitable surfaces can require additional work.
Inspecting the wall
The artist or responsible contractor should assess the wall for issues such as peeling paint, cracks, uneven surfaces, moisture damage, and unstable coatings.
These problems can affect paint adhesion and the durability of the mural.
Cleaning
Dust, grease, dirt, and other contaminants should be removed using methods appropriate for the surface.
The wall must be allowed to dry sufficiently.
Repairing imperfections
Small cracks or holes may require patching and sanding.
More substantial damage, particularly recurring moisture problems, should be addressed before the mural project proceeds.
Applying primer
Depending on the wall's condition and existing finish, an appropriate primer may be necessary.
Primer can improve adhesion and create a more consistent painting surface.
Drying and recoating times vary according to the product and environmental conditions.
How long does wall preparation take?
For a clean interior wall requiring minimal work, preparation may take only part of a day.
A wall requiring patching, priming, or more substantial repairs could need several days or longer.
Exterior masonry projects may require additional assessment, cleaning, and preparation.
Professional tip: Don't rush surface preparation to save time. A properly prepared wall provides a more reliable foundation for the finished artwork.
4. Transferring the Design Onto the Wall
Once the surface is ready, the next step is transferring the approved composition.
This is where the design begins to take shape at its final scale.
Artists use several techniques depending on the type of artwork and the characteristics of the wall.
Freehand drawing
Some artists draw the initial composition directly onto the wall using light pencil or other suitable marking tools.
This approach works particularly well for expressive artwork, organic shapes, and compositions that allow some flexibility.
Grid method
The grid method involves dividing the reference design and wall into corresponding sections.
The artist then transfers the composition square by square.
This technique can be useful for portraits, architectural subjects, and detailed illustrations where proportions are important.
Projector method
A projector allows the artist to display the design directly onto the wall and trace important outlines.
This can be particularly efficient for complex compositions when the room provides suitable lighting and projection distance.
How long does transferring a mural take?
A simple composition may take only a few hours to lay out.
A large or highly detailed design could require an entire day or longer.
Accurate layout is important because correcting proportions becomes more difficult once significant painting has begun.
5. Background Painting and Colour Blocking
After the design has been transferred, the artist usually begins establishing the largest areas of colour.
This stage is often called blocking in.
Instead of immediately painting intricate details, the artist focuses on the major shapes, background colours, and overall composition.
For example, a landscape mural might begin with the sky, mountains, and large foreground shapes.
A portrait mural may start with the background, overall silhouette, and major areas of light and shadow.
A graffiti mural may begin with broad colour fields and large lettering shapes.
Why this stage is important
Establishing the background helps create a foundation for the rest of the artwork.
It also allows the artist to evaluate colour relationships across the entire wall.
Large rollers may be used for broad uniform sections, while brushes and other tools are used for more controlled shapes.
Depending on the paint system, multiple coats may be necessary to achieve the desired coverage.
How long does colour blocking take?
For a relatively simple interior mural, background painting and colour blocking may take a few hours to a full working day.
Complex compositions with numerous overlapping elements may require longer.
The artist must also account for drying and recoating times between layers.
6. Adding Details, Depth, and Texture
This is often the most time-consuming stage of mural painting.
Once the main composition is established, the artist begins refining shapes, developing lighting, adding textures, and introducing smaller details.
The amount of work depends heavily on the artistic style.
Realistic murals
Portraits, wildlife paintings, and detailed landscapes require careful control of proportions, shading, and colour transitions.
A realistic face, for example, may involve multiple layers of painting to develop convincing skin tones, facial features, and lighting.
Graffiti murals
Graffiti-inspired artwork may require intricate lettering, outlines, colour gradients, shadows, and layered visual effects.
Although some sections can be completed quickly, elaborate compositions may require extensive detail.
Botanical murals
Detailed botanical artwork can involve carefully shaped leaves, flowers, stems, and subtle colour transitions.
A minimalist botanical composition may be relatively quick, while an elaborate floral mural can take several days.
Abstract murals
Abstract artwork varies widely in complexity.
A composition featuring simple geometric shapes may be completed efficiently.
An expressive painting with many layers, textures, and carefully developed colour relationships can require considerably more time.
Why detailed murals take longer
The most important consideration isn't simply the number of objects in the design.
It's the level of precision required to create the intended appearance.
This is why two murals covering the same wall can have dramatically different painting schedules.
7. How Long Does a Nursery Mural Take?
Nursery murals are among the most personal residential commissions.
They often feature animals, clouds, landscapes, flowers, world maps, or imaginative storybook scenes.
The timeline depends on how detailed the artwork will be.
A simple composition featuring soft clouds and a few decorative elements may be relatively quick to paint.
A detailed underwater mural featuring whales, turtles, coral, and multiple illustrated animals can require considerably more time.
Example: Woodland nursery mural
Imagine an 8-by-10-foot nursery wall featuring deer, rabbits, trees, mountains, and soft clouds.
The project might involve several days of painting after the design has been approved and the surface prepared.
If the mural includes realistic animal anatomy or numerous intricate details, the schedule may be longer.
Planning around your baby's arrival
If you're commissioning a nursery mural, avoid scheduling the work at the last possible moment.
Allow time for design development, painting, ventilation, drying, curing, and arranging the furniture.
Follow the paint manufacturer's guidance regarding when the room can be safely occupied.

8. How Long Does a Living Room Mural Take?
Living room murals range from simple decorative compositions to elaborate works of fine art.
A minimalist line drawing or geometric mural might require only one or two painting days.
A detailed botanical feature wall, panoramic landscape, or large realistic portrait may require considerably longer.
Example: Living room botanical mural
Consider a 10-foot-wide feature wall behind a sofa.
The design features oversized leaves, delicate flowers, and a carefully coordinated colour palette.
A moderately detailed version might take two to five painting days, depending on the final composition.
An elaborate version featuring realistic flowers and complex colour transitions could take longer.
Furniture and accessibility
Living room projects often require moving furniture away from the wall.
The artist also needs adequate working space for equipment, supplies, and movement.
Preparing the room before the painting begins can make the process more efficient.

9. How Long Does a Commercial Mural Take?
Commercial mural projects often involve additional planning beyond the artwork itself.
Restaurants, offices, retail stores, gyms, and hospitality spaces have operational requirements that may influence the schedule.
For example, a restaurant might require painting outside its regular opening hours.
An office mural may need to be completed around employee schedules or renovation work.
Large commercial spaces may also have restricted access, specific safety requirements, or equipment limitations.
Example: Restaurant graffiti mural
Imagine a restaurant commissioning a 15-by-10-foot graffiti-inspired mural.
The artwork includes custom lettering, colourful abstract shapes, and several detailed illustrated elements.
Depending on the complexity, preparation, and working conditions, the painting might take several days to over a week.
However, design approval, scheduling, and site preparation could extend the total project duration.
Coordinate with renovations
If the business is undergoing renovations, the mural should be integrated into the overall project schedule.
For example, wall repairs and essential preparation should generally be completed before painting begins.
Certain fixtures, furniture, or signage may be better installed after the mural is finished.

10. How Long Does an Outdoor Mural Take?
Exterior murals can require considerably more time than indoor projects.
In addition to the size and complexity of the artwork, outdoor painting is influenced by weather conditions, wall materials, access requirements, and local regulations.
Weather conditions
Rain, strong winds, excessive heat, high humidity, and low temperatures can interfere with painting.
The artist must work within the application conditions specified by the paint manufacturer.
Outdoor projects may therefore require flexible scheduling.
Wall preparation
Exterior surfaces can require extensive cleaning, repairs, or priming before painting.
Brick, concrete, and rendered surfaces may have different preparation requirements.
Working at height
Large outdoor murals may require scaffolding or mobile elevated work platforms.
The setup, inspection, and safe operation of this equipment can influence the schedule.
Permits and approvals
Depending on the location and nature of the artwork, municipal approvals may be required.
For commercial properties in Toronto, it is particularly important to confirm whether a proposed exterior mural is subject to local signage or other regulations.
Example: Large exterior mural
A mural covering the side of a commercial building could require several weeks of painting and preparation.
For particularly large or complex projects, the schedule may extend considerably beyond that.
11. How Long Does Mural Paint Take to Dry?
There's an important difference between paint that feels dry to the touch and paint that has fully cured.
Many water-based acrylic paints become touch-dry relatively quickly under suitable conditions.
However, drying and recoating times depend on the product, application thickness, temperature, humidity, and airflow.
Full curing can take substantially longer.
Why drying time matters
Applying additional layers before the previous coating is ready can affect the appearance or performance of the finish.
Likewise, cleaning or placing furniture against a freshly painted wall too early may damage the artwork.
What about protective coatings?
Some murals receive a protective clear coating after painting.
If a protective finish is appropriate, the artist must ensure that the underlying paint has reached the required condition before application.
The coating will also have its own drying and curing requirements.
For this reason, always follow the manufacturer's instructions and your mural artist's guidance.
Important: A mural being visually complete doesn't automatically mean the wall is ready for contact, cleaning, or normal use.
12. Can a Mural Be Completed in One Day?
Yes, certain murals can be completed in a single painting day.
However, this depends on the design and the condition of the wall.
Examples may include relatively small geometric compositions, simple decorative shapes, minimal line artwork, and limited-colour designs.
A highly detailed portrait or elaborate landscape generally requires more time.
What about urgent commissions?
Some businesses need artwork completed before an event, launch, or opening.
If you have a tight deadline, discuss it with the artist as early as possible.
A simpler design or smaller painted area may be achievable within a shorter period.
However, essential wall preparation, safety procedures, and paint drying requirements should never be compromised simply to meet a deadline.
13. How to Make the Mural Painting Process More Efficient
Although the artist is responsible for executing the artwork, clients can help keep the project organised.
Provide accurate wall dimensions
Measurements allow the artist to estimate the project's scale and plan the design.
Share clear reference images
Examples of colours, styles, and subjects can help communicate your vision.
Approve the design before painting begins
Significant changes during the painting stage can result in delays and additional costs.
Prepare the working area
Move furniture, clear obstacles, and arrange access according to the agreed plan.
Communicate scheduling restrictions
Let the artist know about business hours, renovation deadlines, building access requirements, or other limitations.
Plan ahead
Allow sufficient time for design development, painting, drying, and any final finishing work.
The smoother the preparation and communication, the easier it becomes for the artist to concentrate on producing the artwork.
14. Does a Larger Mural Always Take Longer?
Not necessarily.
Although large murals usually involve more surface area, artistic complexity can have a greater influence on painting time.
Consider two hypothetical projects.
The first is a 200-square-foot mural featuring bold geometric shapes and a limited colour palette.
The second is an 80-square-foot realistic portrait with detailed facial features, subtle colour transitions, and intricate background elements.
Despite being smaller, the portrait could require more painting time.
This is why professional mural artists often estimate project duration based on a combination of size, complexity, painting technique, and working conditions.
When requesting a quote, providing examples of the desired artistic style can be just as important as providing the wall dimensions.
15. When Should You Contact a Mural Artist?
If you're planning a custom mural, contacting an artist early gives you more flexibility.
The ideal lead time depends on the project and the artist's availability.
For a residential feature wall, consider reaching out several weeks before your preferred completion date.
For commercial projects tied to renovations or opening dates, earlier discussions may be beneficial.
Large exterior murals can require additional time for site assessments, access planning, and approvals.
Planning a mural for a special event?
If the mural is connected to a birthday, business launch, renovation, or other deadline, mention the date during the first consultation.
The artist can then assess whether the schedule is realistic.
A clear timeline makes it easier to balance artistic quality with practical requirements.
Example Timeline: From Initial Inquiry to Finished Mural
To understand how the stages come together, consider a hypothetical residential mural project.
StageIllustrative durationInitial consultation and project details1–3 daysConcept design and revisions3–10 daysFinal approval and schedulingVariableWall preparation1–2 daysLayout and painting3–5 daysFinishing and required drying/curingProduct-dependent
These stages may overlap, and the overall calendar can vary significantly according to artist availability, approvals, and site conditions.
For example, a mural that requires four days of actual painting may still involve several weeks between the initial inquiry and final completion.
Understanding this distinction is especially important when coordinating with other renovation activities.
