Can You Paint Over Brick or Stone in Calgary Homes?

Brick and stone surfaces add character and charm to many Calgary homes, but there may come a time when you consider painting these surfaces. Whether you're looking to refresh your home's appearance, address discoloration, or simply want a change, painting brick or stone is a significant decision that requires careful consideration, especially in Calgary's unique climate.

The Pros of Painting Brick or Stone in Calgary

• Enhanced Curb Appeal: A fresh coat of paint can dramatically transform the look of your home, giving it a modern update.
• Protection from Elements: Quality paint can provide an additional barrier against Calgary's harsh weather conditions, including freezing temperatures, snow, and summer heat.
• Covers Imperfections: Paint can hide stains, discoloration, or mismatched repairs that may have occurred over time.
• Energy Efficiency: Lighter colored paint can reflect heat, potentially improving your home's energy efficiency during Calgary's summer months.
• Customization: Painting allows you to match your brick or stone to your desired color scheme, giving you more design flexibility.

The Cons of Painting Brick or Stone

• Permanence: Once painted, it's extremely difficult to return brick or stone to its original state.
• Maintenance: Painted surfaces will require periodic repainting to maintain their appearance, typically every 3-5 years in Calgary's climate.
• Moisture Issues: Improper preparation or using the wrong type of paint can trap moisture within the brick or stone, leading to damage, especially during Calgary's freeze-thaw cycles.
• Historical Value: Painting original brick or stone on heritage homes may reduce their historical value and authenticity.
• Potential for Peeling: In Calgary's climate, with significant temperature fluctuations, poor quality paint jobs can lead to peeling and flaking.

Special Considerations for Calgary's Climate

Calgary's climate presents unique challenges for painted brick and stone surfaces:

• Freeze-Thaw Cycles: Calgary experiences numerous freeze-thaw cycles throughout the year, which can cause paint to crack if the surface wasn't properly prepared or if the wrong paint was used.
• Low Humidity: Calgary's dry climate can affect how paint adheres and cures on masonry surfaces.
• UV Exposure: The high altitude means more intense UV exposure, which can cause paint to fade more quickly than in other regions.
• Chinook Winds: These warm, dry winds can cause rapid temperature changes that stress painted surfaces.

Proper Preparation for Painting Brick or Stone in Calgary

If you decide to paint your brick or stone, proper preparation is crucial for long-lasting results:

1. Thorough Cleaning: Remove all dirt, grime, and efflorescence (white, powdery deposits) using a pressure washer and appropriate cleaners.
2. Repairs: Address any damaged mortar, cracks, or loose pieces before painting.
3. Allow Proper Drying Time: Ensure the surface is completely dry before applying primer. In Calgary, this may take longer during humid periods.
4. Quality Primer: Use a high-quality masonry primer specifically designed for brick or stone surfaces.
5. Appropriate Paint Selection: Choose breathable, masonry-specific paint that allows moisture to escape rather than becoming trapped in the brick or stone.

Best Paint Types for Brick and Stone in Calgary

Not all paints are suitable for masonry surfaces in our climate:

• Mineral-Based Paints: These are highly breathable and work well with masonry surfaces in Calgary's variable climate.
• Acrylic Latex Paints: These offer good flexibility and adhesion, important qualities for withstanding Calgary's temperature fluctuations.
• Elastomeric Paints: These provide excellent waterproofing and can stretch to cover small cracks, making them suitable for Calgary's freeze-thaw cycles.

Avoid oil-based or alkyd paints on exterior masonry, as they don't allow proper moisture movement and can lead to problems in Calgary's climate.

Maintenance Requirements

Once you've painted brick or stone, regular maintenance is essential:

• Inspect annually for cracks, peeling, or signs of moisture problems.
• Clean painted surfaces gently to remove dirt and pollutants.
• Touch up damaged areas promptly to prevent moisture intrusion.
• Plan for repainting every 3-7 years, depending on exposure and paint quality.

When to Consider Professional Help

While some homeowners may tackle painting brick or stone as a DIY project, there are several reasons to consider hiring professional exterior painters in Calgary:

• Professionals understand the specific challenges of Calgary's climate.
• They have experience with proper preparation techniques for masonry surfaces.
• They can recommend the most appropriate primers and paints for your specific situation.
• Professional equipment ensures even application and better coverage.
• Many offer warranties on their work, providing peace of mind.

Conclusion

Painting brick or stone can be a viable option for Calgary homeowners looking to update their home's appearance or address certain issues. However, it's a decision that shouldn't be taken lightly given the permanence and maintenance requirements involved. By understanding the pros and cons, considering Calgary's unique climate challenges, and following proper preparation and application techniques, you can achieve attractive and durable results.
