How To Paint a Brick House

Painting a brick house exterior is very different from painting siding or trim.

Brick is a porous material that interacts with moisture, temperature, and the environment in ways that require careful preparation and the right painting techniques.

If done correctly, painting brick can improve curb appeal and protect the surface. If done incorrectly, it can lead to peeling, moisture issues, and premature failure.

This guide explains the key exterior brick house painting techniques homeowners should understand before starting a project.

If you’re planning to update your brick exterior, our team provides professional exterior painting Toronto services with proper preparation and coatings designed for masonry surfaces.

Is Painting Exterior Brick a Good Idea?

Painting brick is a permanent decision.

Once brick is painted, it typically requires ongoing maintenance and repainting over time.

However, it may be a good option if:

  • the brick is heavily stained or discolored
  • previous coatings already exist
  • you want a fully uniform colour change

Before painting, it is important to evaluate whether alternatives like staining may better suit your goals.

Understanding Brick Before You Paint

Brick is designed to absorb and release moisture.

This natural process is important for maintaining the structural integrity of the masonry.

In Toronto, where homes experience:

  • rain and humidity
  • freeze-thaw cycles
  • temperature fluctuations

choosing the right system is essential.

Paint systems that do not allow proper moisture movement can trap water inside the brick, leading to issues over time.

Key Exterior Brick House Painting Techniques

Surface Cleaning and Preparation

Proper cleaning is the foundation of any successful brick painting project.

This typically involves:

  • removing dirt and debris
  • cleaning mildew or organic growth
  • ensuring the surface is fully dry before painting

Without proper cleaning, paint will not adhere correctly.

Repairing Brick and Mortar

Before painting, inspect the brick and mortar for damage.

Look for:

  • cracked mortar joints
  • loose or damaged bricks
  • areas of deterioration

These issues should be repaired before applying any coating.

For homes with additional exterior damage, services like exterior wood repair and carpentry may also be needed to prepare surrounding surfaces.

Choosing the Right Primer

Primer plays a critical role when painting brick.

A masonry-specific primer helps:

  • improve adhesion
  • create a consistent base
  • support long-term durability

Skipping primer is one of the most common reasons brick paint jobs fail.

Applying the Paint Correctly

When applying paint to brick, technique matters.

Best practices include:

  • applying thin, even coats
  • working paint into the porous surface
  • avoiding heavy buildup

Depending on the surface, both brushes and rollers may be used to ensure full coverage.

Managing Moisture and Breathability

One of the most important brick painting techniques is understanding moisture.

Using breathable coatings helps reduce the risk of trapped moisture.

This is especially important in climates like Toronto, where moisture cycles are frequent.

Common Mistakes When Painting Brick Exteriors

Many problems with painted brick come from avoidable mistakes.

These include:

  • painting over dirty or damp surfaces
  • skipping repairs
  • using the wrong type of paint
  • applying paint too thickly

Taking the time to prepare properly is essential for long-term performance.

Brick Painting vs Brick Staining

Before committing to painting, homeowners should understand the difference between painting and staining.

Painting creates a solid layer over the brick.

Staining penetrates the surface and preserves the natural texture.

Staining may be a better option when you want to maintain the look of the brick while adjusting the colour.

Painting is typically chosen when a full colour change is required.

When to Hire a Professional for Brick Painting

Painting brick is more complex than standard exterior painting.

You may want to hire a professional if:

  • the surface requires significant preparation
  • your home has multiple exterior materials
  • you want consistent, long-lasting results
  • you are completing a full exterior refresh

Professionals understand how to properly prepare masonry surfaces and select coatings that perform well over time.

Conclusion: Getting Long-Lasting Results on Brick

Exterior brick painting can transform the appearance of your home, but it must be done carefully.

The key factors for success include:

  • proper preparation
  • correct product selection
  • attention to moisture and breathability

Rushing the process or skipping steps often leads to early failure.

Freshly painted exterior brick house in Toronto showing dramatic transformation

Painted brick is one of the most dramatic exterior transformations available to Toronto homeowners — and one of the most permanent decisions on any home.

Before You Paint: Why Brick Painting Is a Permanent Decision

Most homeowners approach brick painting the way they would approach painting siding or trim, but brick painting is not the same decision. Painted brick is extremely difficult and expensive to reverse. Chemical stripping of paint from brick is labour-intensive and rarely achieves a clean result. Sandblasting can remove paint but risks damaging the brick face, particularly on older softer brick common in Toronto homes built before the 1960s. Once you paint brick, you are committing to repainting it on a regular cycle for the life of the building.

That does not mean painting is the wrong choice. It means you should make the decision with full information, and understand the maintenance commitment that comes with it.

Brick Painting vs. Brick Staining: Which Is Right for Your Home?

The most important decision before any brick project is whether to paint or stain. These are not interchangeable options. They work differently on the brick surface, produce different visual results, and have fundamentally different maintenance profiles. Here is the full side-by-side breakdown.

Feature Brick Painting Brick Staining
How it works Sits on top of the brick as a film coating Penetrates into the brick and bonds chemically
Appearance Opaque, uniform, covers brick texture Semi-transparent, preserves natural brick texture
Breathability Low, traps moisture if wrong products used High, allows moisture vapour to escape through brick
Risk of peeling High over time, especially with freeze-thaw Very low, stain does not form a film to peel
Lifespan in Toronto 8 to 12 years with quality products and proper prep 15 to 25 years, sometimes described as near-permanent
Maintenance cycle Repaint every 8 to 12 years Minimal, no recoating cycle required
Reversibility Difficult, chemical strip or sandblast required Effectively permanent, cannot be unstained
Works on previously sealed brick Yes No, stain cannot penetrate sealed or painted brick
Upfront cost Lower per sq ft Slightly higher upfront, lower lifetime cost
Home Painters Toronto warranty 3 years on exterior painting 15 years on brick staining
Best for Brick that is already painted, sealed, or where full opaque colour is required Unpainted, unsealed brick where a natural look and low maintenance are priorities

The practical decision rule our team uses with Toronto homeowners is straightforward. If the brick has never been painted or sealed, staining is almost always the better long-term investment. The 15-year warranty we back it with reflects that confidence. If the brick has already been painted or has a sealant coat, staining is not possible because the stain cannot penetrate through an existing film coating. In that case, brick painting is the right path forward, and doing it properly with the right masonry primer and product system is what determines how long it holds up. For a detailed breakdown of why staining outperforms painting on most Toronto brick surfaces, see our full brick staining vs. painting guide.

Why Toronto's Climate Makes Brick Painting More Demanding

Brick painting in Toronto is far more challenging than many homeowners realize because the city's climate is extremely hard on painted masonry surfaces. Toronto experiences more than 100 freeze-thaw cycles per year, which means brick walls are under repeated stress from moisture expansion and contraction. Brick is a naturally porous material designed to absorb and release moisture as conditions change. When paint is applied on top, it creates a film on the surface of the brick. If moisture from inside the wall or from rain and condensation gets behind that film, which it inevitably does over time through hairline cracks in the mortar or the paint film itself, that moisture freezes in winter, expands, and forces the paint off the brick from behind. The result is bubbling, peeling, and in severe cases, spalling of the brick face itself.

This is not a product failure. It is a fundamental physical incompatibility between a sealed film coating and the way brick naturally manages moisture. The way to manage it is through product selection, specifically using masonry-specific, vapour-permeable primers and elastomeric topcoats that flex with the brick rather than forming a rigid, sealed film, and through correct surface preparation before any paint goes on.

According to the Canada Mortgage and Housing Corporation's guidance on masonry and moisture in Canadian homes, masonry walls in Canadian climates require coatings that allow vapour transmission rather than trapping moisture behind a sealed surface. The choice of primer and topcoat on Toronto brick is therefore not a cosmetic decision. It is a structural one.

Homes in older Toronto neighbourhoods like Riverdale, The Annex, Cabbagetown, Leslieville, North York, and Etobicoke are particularly relevant here. Many of these homes have older, softer brick from the 1940s through 1970s that is more porous and more susceptible to moisture damage than modern brick. The same prep and product discipline applies but with even less margin for error.

How to Paint a Brick House: Step-by-Step

1
Prep the Brick Surface When painting the exterior brick siding of your home, you need to pressure wash the brick well and clear of dirt and debris, then use a bleach solution to scrub clean the brick of any remnants that are stuck to the brick, let the bleach solution sit for a half hour, and then wash or wipe off. The pressure wash and bleach clean is the foundation of the entire job. Paint applied to dirty, mouldy, or effloresced brick will not adhere properly no matter what product you use. For brick with visible white salt deposits (efflorescence), these must be removed with a stiff masonry brush and a diluted masonry cleaner before the bleach step. Efflorescence is water-soluble salts migrating to the brick surface, and painting over them creates a weak bond that will lift as the salts continue pushing outward. Allow the brick to dry completely after washing. For Toronto outdoor conditions, plan for a minimum of 48 to 72 hours of dry weather after washing before priming or painting. Brick holds moisture far longer than it appears to on the surface, and painting over damp brick is a guaranteed path to early adhesion failure.
2
Mask and Protect Covering your windows with newspaper or cardboard would be optimal, but taping them off with painter's tape is still efficient. Depending on whether you are using a paint gun or a regular roller and brush to paint your brick house's exterior, decide if you want to cover up all windows and doors or tape around them. Lay down a drop cloth or tarp on the ground beneath where you are working, and make sure there aren't any objects that you might trip over.
3
Repair Cracks and Mortar Repair any cracks or issues with acrylic caulking. Let it dry for a minimum of 4.5 hours. For mortar joints that are crumbling, recessed, or cracked, repointing with matching mortar compound is a critical step before painting. Any unfilled crack or void in the mortar will allow water to enter behind the paint film from the first heavy rain. Inspect all mortar joints carefully before painting begins, not just obvious cracks, but soft or recessed areas that will allow water infiltration. For more significant mortar repair or brick replacement, our brick and mortar repair service handles this as part of our full exterior scope.
4
Apply Primer Using a latex primer, prime the surface of the brick using a roller, brush, or spray gun. Not all primers are appropriate for exterior brick. Standard interior or general exterior latex primer is not the right product here. For exterior brick painting in Toronto, you need a masonry-specific primer that is:
  • Alkali-resistant: Brick is highly alkaline, and paint or primer not rated for alkali contact will fail at the adhesion level before the topcoat ever gets tested.
  • Vapour-permeable: The primer must allow moisture to move through it rather than creating a sealed vapour barrier.
  • Penetrating: A good masonry primer soaks into the brick surface rather than sitting on top, creating the chemical bridge the topcoat needs to bond to.
Reliable primer options for exterior brick include Benjamin Moore Fresh Start Masonry Primer and Sherwin-Williams Loxon Concrete and Masonry Primer. Apply one full coat with a thick-nap roller (a 19mm or 25mm nap is appropriate for rough brick texture) and allow full cure time per the manufacturer's specifications before the first topcoat goes on.
5
Apply the Paint A spray gun is often the easiest and most efficient way to paint exterior brick, especially on larger surfaces, but it should only be used if you know how to operate it properly. Otherwise, a roller or paintbrush can still provide excellent coverage and control. Apply a few coats of primer to any areas that need it and allow it to dry fully before painting. An elastodynamics paint is a denser paint and will fill in holes and cracks a lot easier than most other exterior paint types. This paint is also known for repelling water, so it is an extremely wise choice. Using a paint sprayer you should apply a coat of paint from one side to the other a lot faster than using a roller or a paintbrush. If you use a roller or a paintbrush, you need to layer up more paint on the brush to fill in the cracks evenly, but work carefully or you will get uneven results. When using a roller, start from top to bottom, and use a paintbrush where you see spots missed by the roller. For most Toronto residential brick painting projects, two topcoats of elastomeric masonry paint are the professional standard. The first coat establishes coverage and seals the primed surface. The second coat builds the film thickness required for durability and weather resistance. Do not attempt to apply a single heavy coat in place of two proper coats. A thick single application is more likely to sag, trap air, and form an uneven film than two properly-applied coats. Allow the manufacturer's specified recoat time between coats, typically 4 to 6 hours for water-based masonry coatings in normal conditions.

Masonry-specific, alkali-resistant primer applied to properly cleaned and repaired brick is the step that determines how long the finished paint job holds up in Toronto's climate.

Best Paint for Brick Exterior: Product Recommendations

Choosing the right topcoat for exterior brick painting in Toronto is not a question of brand preference. It is a question of product category. The paint must be formulated specifically for masonry, must be vapour-permeable, and must have the elasticity to flex with the brick through freeze-thaw cycling without cracking.

Product Type Key Features Best For
Benjamin Moore Elastomeric Masonry Waterproof Coating Elastomeric masonry Fills hairline cracks, highly flexible, water-repellent Older brick with minor cracking, full exterior repaints
Sherwin-Williams Loxon Elastomeric Coating Elastomeric masonry Excellent adhesion, vapour-permeable, UV stable New and previously painted brick in good condition
Benjamin Moore Ultra Spec Masonry Interior/Exterior Acrylic masonry Good for cleaner, modern masonry surfaces Newer brick in good condition, lighter colour applications
Sherwin-Williams Masonry Conditioner Masonry prep/primer Deep penetrating, stabilizes chalking and porous surfaces Heavily weathered or chalking brick before any topcoat
CMHC-recommended vapour-permeable masonry coatings Vapour-permeable acrylic Allows brick to breathe, reduces peeling risk All exterior brick in Canadian climates
Pro Tip: The one product category to avoid on exterior brick is standard exterior latex wall paint not specifically rated for masonry. While it may look acceptable for a season or two, it does not have the elasticity or vapour permeability that brick requires and will fail on the typical Toronto freeze-thaw cycle. The extra cost of a masonry-specific product over standard exterior latex is small compared to the cost of peeling and repainting.

How to Choose the Best Colour to Paint a Brick House

Colour Trends for Painted Brick in Toronto in 2026

Painted brick gives Toronto homeowners the most dramatic range of colour choices available on any exterior surface, because paint is fully opaque and can take any colour on the spectrum. The most popular directions our team sees across Toronto and the GTA in 2026 reflect the broader trend toward sophisticated neutrals and high contrast combinations.

White and off-white painted brick remains the single most requested colour, particularly on homes in Roncesvalles, South Etobicoke, and the Annex where owners want a fresh, modern look while keeping the architectural character of the brick beneath. Benjamin Moore White Dove and Chantilly Lace are both consistently popular choices for Toronto brick homes.

Dark painted brick, specifically charcoal, near-black, and deep grey tones, has been gaining significant momentum. Homes in Leslieville, Riverdale, and East York where owners want a bold, contemporary statement are increasingly choosing colours like Benjamin Moore Kendall Charcoal, Sherwin-Williams Iron Ore, and Benjamin Moore Wrought Iron for full exterior brick painting. These dark tones absorb more heat from direct sunlight than lighter colours, which is worth considering on south-facing brick elevations.

For warm neutral options that read as updated without going fully dramatic, greige and warm greige tones (a blend of grey and beige) work well on the red and orange brick tones common on Toronto homes built between 1940 and 1980. Benjamin Moore Revere Pewter and Sherwin-Williams Accessible Beige are reliable choices in this category.

Tips for Choosing a Brick Painting Colour

  • Consider the fixed elements of your home that you are not changing: roof colour, stone or concrete details, window frame colour, and driveway material. Your brick paint colour needs to work with all of these.
  • Look at the neighbourhood. Most Toronto neighbourhoods have a general character, and a colour that is dramatically at odds with the surrounding streetscape can affect resale value.
  • Order large paint samples or a peel-and-stick test patch before committing. Brick absorbs paint differently than smooth surfaces, and colours always look different at full scale on a textured exterior than they do on a small chip.
  • Dark colours on brick require careful quality control on prep. Any mortar patches or repairs will absorb paint differently from the surrounding brick and may show more obviously under dark colours than light ones.

Common Brick Painting Mistakes to Avoid

After working on brick homes across Toronto and the GTA for over 37 years, our team has seen the same mistakes on DIY and unprepared contractor jobs repeatedly. Here are the ones that matter most.

Mistakes That Cause Early Paint Failure on Brick:
  • Skipping the masonry primer or using the wrong primer. This is the single most common reason painted brick jobs fail early. Standard exterior primers are not alkali-resistant and do not penetrate brick adequately. A masonry-specific primer is not optional.
  • Painting over damp or freshly washed brick. Brick retains moisture far longer than its surface suggests. Allow a minimum of 48 to 72 hours of dry weather after any washing before priming or painting.
  • Painting over efflorescence without treating it first. The salts will continue migrating to the surface and will push the paint off from behind. Efflorescence must be removed and the source of moisture migration addressed before painting.
  • Using standard exterior latex instead of elastomeric masonry paint. Standard latex lacks the flexibility and masonry adhesion required for exterior brick in Toronto's freeze-thaw climate. It is not a suitable substitute regardless of how premium the brand.
  • Applying one heavy coat instead of two proper coats. A thick single coat on rough brick creates an uneven film with air pockets and is more susceptible to early cracking than two properly applied thinner coats.
  • Not repairing mortar joints before painting. Unfilled mortar cracks allow water infiltration behind the paint film from the first rain after application. All mortar gaps must be addressed before any paint goes on.

How Much Does It Cost to Paint Brick Exterior in Toronto?

DIY Cost Estimate

  • Masonry alkali-resistant primer (Benjamin Moore Fresh Start or Sherwin-Williams Loxon): $60 to $90 per pail, covering approximately 30 to 50 sq ft per coat on rough brick
  • Elastomeric masonry topcoat: $80 to $130 per pail
  • Masonry cleaner, efflorescence remover, bleach solution: $30 to $60
  • Acrylic caulk for crack and mortar repair: $15 to $30
  • Thick-nap rollers, brushes, drop cloths, masking tape: $50 to $90
  • Pressure washer rental: $60 to $90 per day
  • Total DIY materials for an average Toronto semi-detached or detached home front elevation (approximately 400 to 600 sq ft of brick): $400 to $750 CAD

For a full exterior repaint of a Toronto detached home (1,000 sq ft of brick or more), DIY material costs will run $700 to $1,400 CAD before any tool rental or repair costs are factored in.

Professional Cost Estimate

Professional exterior brick painting in Toronto typically ranges from $2,500 to $7,500 CAD for a full residential exterior, depending on the size of the home, the condition of the brick and mortar, the number of elevations being painted, whether scaffolding or lifts are required, and whether repair work is needed before painting begins.

The premium for professional work is concentrated in two areas: surface prep and product knowledge. An elastomeric masonry system applied over a correctly prepared and primed brick surface will perform significantly better over the full repaint cycle than the same product applied over inadequate prep. Home Painters Toronto backs all exterior brick painting work with a 3-year warranty and exterior brick staining with a 15-year warranty, reflecting the difference in expected performance between the two options.

Real Project: Exterior Brick Painting on a Toronto Home

Leslieville Semi-Detached: Full Brick Repaint with Mortar Repair and Elastomeric Topcoat

The situation: The homeowner of a semi-detached brick home in Leslieville wanted to repaint the front and side elevations of their home, which had been painted approximately ten years prior. The existing paint had begun to show surface peeling in several areas near the mortar joints and along the base of the front elevation where splash-back moisture from the front walkway had accelerated deterioration. The homeowner had selected a deep charcoal colour and wanted a clean, modern result.

What the job involved: Our team began with a full inspection of all brick and mortar surfaces. Several mortar joints required repointing before any prep or painting work could begin, and those repairs were handled by our exterior carpentry team in advance of the painting crew. The full front and side elevations were pressure washed, treated with a bleach solution for mould and biological growth, and allowed to dry for 72 hours before work continued. All remaining loose and flaking paint was scraped back. Efflorescence deposits around the base and near several window openings were treated with a masonry cleaner and removed before priming. A full coat of Sherwin-Williams Loxon Masonry Primer was applied by roller to all brick surfaces, with particular attention to the mortar joints and previously peeling areas. Two coats of Benjamin Moore Elastomeric Masonry Waterproof Coating in the homeowner's chosen charcoal tone were then applied over the full elevation, with a brush used on all mortar joints and edges.

The result: A clean, uniform deep charcoal finish across both elevations with no visible peeling and sharp edges at all window and door openings. The homeowner noted a dramatic change in the home's street presence, which read as significantly more contemporary and deliberate than the previous light beige paint job. The mortar repair work done before painting was not visible in the finished result, as the elastomeric topcoat's flexibility and fill characteristics smoothed over the repaired areas seamlessly.

Frequently Asked Questions About Brick Painting

Is it a good idea to paint brick on a house in Toronto?

It depends on the condition of the brick and what outcome you are looking for. For brick that has never been painted or sealed, staining is usually the better long-term investment because it allows the brick to breathe, lasts 15 to 25 years, and does not require a maintenance recoat cycle. For brick that has already been painted, or where a fully opaque colour change is required, painting with the right masonry primer and elastomeric topcoat is a perfectly viable option and will hold up well in Toronto's climate when done correctly. The key is using masonry-specific products and doing the prep work properly, particularly mortar repair and efflorescence treatment before any primer goes on.

What kind of paint do you use on a brick house exterior?

Exterior brick requires an elastomeric masonry paint or a vapour-permeable 100% acrylic masonry coating specifically formulated for brick and masonry surfaces. Standard exterior latex wall paint is not appropriate for brick. It lacks the alkali resistance, flexibility, and vapour permeability that brick requires in a Canadian freeze-thaw climate. Products like Benjamin Moore Elastomeric Masonry Waterproof Coating and Sherwin-Williams Loxon Elastomeric Coating are the professional-grade options our team uses regularly on Toronto brick homes.

How long does paint last on exterior brick in Toronto?

With proper prep, the right masonry primer, and an elastomeric topcoat, a quality exterior brick paint job should last 8 to 12 years in Toronto conditions. Without proper prep, particularly without masonry-specific primer and without addressing efflorescence and mortar cracks before painting, paint on brick can begin failing within 2 to 4 years. The single biggest variable in how long painted brick holds up is how well the surface was prepared before the first coat went on, not the brand of paint used.

What is the difference between painting and staining brick?

Paint forms a film coating on the surface of the brick. It is opaque, covers all of the brick texture and mortar, and produces a dramatic, uniform colour change. Paint traps moisture if wrong products are used and requires repainting every 8 to 12 years. Stain penetrates into the brick and bonds chemically with the masonry. It is semi-transparent, preserves the natural texture and character of the brick, allows the brick to breathe, and lasts 15 to 25 years. Staining is only possible on brick that has never been painted or sealed. If the brick already has a paint or sealant coat, painting is the only option.

Can I paint over previously painted brick?

Yes. If the existing paint is adhering well and is not peeling extensively, you can paint over previously painted brick after cleaning, treating any problem areas, and applying a fresh coat of masonry primer before the topcoat. If the existing paint is peeling significantly, all loose paint must be removed before repainting. Because brick is porous and irregular in texture, complete removal of all existing paint is not always achievable without damaging the brick face, which is why preserving the integrity of each paint coat for as long as possible is preferable to repeated strip-and-repaint cycles.

Do I need to prime brick before painting?

Yes, without exception. A masonry-specific, alkali-resistant primer is required before any topcoat is applied to exterior brick. The alkali content of brick and mortar will attack standard exterior paint primer, causing adhesion failure from the bottom of the paint system upward. A masonry primer penetrates the brick surface, neutralises the alkali, and creates the adhesion base the topcoat needs. Skipping primer on brick is one of the most reliable ways to produce a paint job that fails within a single freeze-thaw winter.

How do I know if my brick can be stained or if it needs to be painted?

The simple test is to splash a small amount of water onto the brick surface. If the water is absorbed into the brick within a few seconds, the brick is porous and unsealed. Staining is possible. If the water beads on the surface and runs off without being absorbed, there is a sealant or previous paint coat on the brick. Staining is not possible because the stain cannot penetrate through the existing film. In that case, painting with a masonry primer and elastomeric topcoat system is the right approach. Our team performs this assessment as part of every brick exterior estimate consultation.
