Kingston, Ontario is known for its rich architectural history, with many homes dating back to the 19th century. While these historic properties have undeniable charm and character, they often present unique challenges when it comes to painting and renovation projects. One of the most common issues homeowners face is dealing with oddly shaped rooms—spaces with curved walls, unusual angles, alcoves, dormers, and other architectural quirks that make standard painting techniques difficult to apply.
At Painters Kingston, we've worked on countless historic homes throughout the city, and we've developed specialized techniques for tackling these challenging spaces. In this guide, we'll share our professional insights to help you successfully paint those tricky, non-standard rooms in your Kingston home.
Understanding the Challenges of Oddly Shaped Rooms
Before diving into specific techniques, it's important to understand what makes these spaces challenging:
- Irregular wall junctions - Where walls meet at unusual angles rather than the standard 90 degrees
- Curved or rounded walls - Common in Victorian and Edwardian homes
- Sloped ceilings - Particularly in attic rooms and under staircases
- Alcoves and recessed areas - Which create shadows and depth perception challenges
- Ornate moldings and trim - Requiring precise cutting-in techniques
- Dormers and bay windows - Creating complex transitions between walls and ceilings
Each of these features requires specific approaches to achieve a professional finish.
Essential Tools for Painting Oddly Shaped Rooms
Success begins with having the right tools. For oddly shaped rooms, we recommend:
- Angled brushes - Essential for cutting in at unusual angles
- Mini rollers - Perfect for small or narrow sections
- Flexible edging tools - These can conform to curved surfaces
- Extension poles with adjustable angles - For reaching high or awkward spots
- Painter's tape designed for curves - More flexible than standard tape
- Contour gauges - For measuring and transferring irregular shapes
- Laser level - Helps maintain straight lines across uneven surfaces

Preparation: The Key to Success
Proper preparation is even more critical when dealing with oddly shaped rooms:
1. Thorough Assessment
Begin by carefully examining the room to identify all the challenging areas. Take photos and measurements of particularly tricky spots. This will help you plan your approach and ensure you have all the necessary tools and materials.
2. Strategic Furniture Removal
If possible, completely empty the room. In oddly shaped spaces, you'll need maximum maneuverability. If furniture must remain, place it in the center and ensure you have at least 3 feet of clearance around all walls.
3. Surface Preparation
Older Kingston homes often have layers of old paint, wallpaper, or plaster issues. Take time to:
- Repair any cracks or damage in plaster walls (common in historic homes)
- Sand uneven surfaces to create a smooth base
- Clean walls thoroughly to remove decades of accumulated dust and grime
- Apply primer specifically designed for older surfaces
Pro Tip: Dealing with Plaster
Many Kingston heritage homes have plaster walls rather than drywall. When preparing plaster surfaces, use a specialized plaster primer to seal the surface and prevent moisture issues. Avoid excessive sanding on plaster walls, as older plaster may contain lead paint or asbestos.
Techniques for Specific Challenges
Curved Walls
Curved walls are common in Kingston's Victorian and Edwardian homes, particularly in bay windows and turrets:
- Use shorter roller strokes than you would on flat walls
- Work in smaller sections, maintaining a wet edge
- Consider using a foam roller, which conforms better to curved surfaces
- For tight curves, apply paint with a brush and then lightly roll to blend

Sloped Ceilings and Dormers
Many older Kingston homes have converted attic spaces with sloped ceilings and dormers:
- Decide where your ceiling color will transition to wall color (typically at the point where the slope begins)
- Use painter's tape to create a clean line at this transition
- Paint the ceiling first, then walls
- For dormers, paint the recessed areas before the main walls
Pro Tip: Color Choices for Sloped Ceilings
In Kingston's older homes with sloped ceilings, painting the sloped portion the same color as the ceiling can make the room feel smaller. Instead, consider painting the sloped section the same color as the walls to create a sense of height and space.
Alcoves and Recessed Areas
Alcoves and recessed areas create depth and character but can be challenging to paint:
- Paint these areas first before moving to the main walls
- Use appropriate lighting to ensure you don't miss spots (a portable work light is ideal)
- Consider using a slightly lighter shade in recessed areas to prevent them from appearing too dark
- Use a mini roller to access tight spaces
Ornate Moldings and Trim
Kingston's heritage homes often feature elaborate moldings and trim work:
- Always paint trim before walls
- Use a high-quality angled brush for precise cutting-in
- Consider using painter's tape specifically designed for delicate surfaces
- Apply paint in the direction of the wood grain
- For intricate details, a small artist's brush can be helpful
Color Strategies for Oddly Shaped Rooms
Color choice can significantly impact how an oddly shaped room is perceived:
Creating Balance
In Kingston's older homes with irregular room shapes, strategic color placement can create visual balance:
- Unifying approach: Using a single color throughout can minimize the perception of odd angles
- Accent approach: Using a darker or contrasting color on a feature wall can intentionally highlight unique architectural elements
- Brightening approach: Lighter colors can make small, oddly shaped rooms feel more spacious
Kingston Heritage Color Palette
For historically appropriate colors that work well in Kingston's older homes, consider heritage color palettes from Benjamin Moore or Sherwin-Williams. These collections offer authentic period colors that complement the architectural style of many Kingston homes while meeting modern quality standards.
Common Mistakes to Avoid
When painting oddly shaped rooms in Kingston's older homes, avoid these common pitfalls:
- Rushing the preparation: Older homes require thorough prep work
- Using low-quality paint: Invest in quality paint that provides good coverage on irregular surfaces
- Ignoring lighting conditions: Odd-shaped rooms often have unusual lighting; test colors under different lighting conditions
- Applying paint too thickly: Multiple thin coats work better than one thick coat, especially on textured or curved surfaces
- Neglecting ventilation: Older Kingston homes may have less ventilation; ensure adequate airflow when painting
When to Call the Professionals
