How do you paint stucco around detailed architectural trim on an Ottawa home?

Painting stucco around detailed architectural trim requires careful preparation and the right technique to achieve clean lines while protecting the stucco's texture and performance in Ottawa's harsh climate.

The key to professional-looking results lies in proper masking and using elastomeric paint specifically designed for stucco surfaces. Start by thoroughly cleaning both the stucco and trim with a pressure washer set to low pressure (1,500 PSI maximum) to avoid damaging the stucco texture. Allow 24-48 hours for complete drying before beginning paint preparation.

For masking detailed trim, use high-quality painter's tape designed for textured surfaces — standard masking tape won't conform properly to stucco's irregular surface. Apply the tape carefully, pressing it firmly into the texture around trim edges. Consider using a plastic putty knife to work the tape into deeper texture grooves. For intricate Victorian-era trim common in Ottawa neighbourhoods like the Glebe or Sandy Hill, you may need to use multiple strips of narrow tape to follow complex curves and details.

Choose elastomeric paint specifically formulated for stucco — regular exterior latex paint will crack and peel within 1-2 years in Ottawa's freeze-thaw environment. Quality elastomeric stucco paint costs $65-85 per gallon and provides the flexibility needed to accommodate thermal movement. Popular brands like Sherwin-Williams Loxon or Benjamin Moore Aura Exterior work well in Ottawa conditions. Plan on $3,000-7,000 for painting a full Ottawa home's stucco, depending on size and trim complexity.

Apply paint using a combination of brush and roller techniques. Use a high-quality angled brush (2.5-3 inches) to carefully cut in around trim details, working the paint into the stucco texture. Follow immediately with a thick-nap roller (3/4 inch minimum) to maintain consistent texture across larger wall areas. Work in manageable sections to maintain a wet edge.

Ottawa's climate demands careful timing for this work. Paint only when temperatures will remain above 10°C for at least 48 hours after application, and avoid painting in direct sunlight on hot summer days when surface temperatures exceed 32°C. The ideal painting season runs from late May through early October. Morning application often works best, allowing the paint to cure before afternoon heat or evening dew.

Remove masking tape while the paint is still slightly tacky — typically 2-4 hours after application depending on temperature and humidity. Pulling tape from fully dried paint can cause peeling along the edges. If you discover small areas where paint bled under the tape, touch them up with a small artist's brush rather than attempting to re-tape and repaint.

For homeowners comfortable with ladder work and detail painting, this project is manageable as a DIY task on single-storey areas. However, hire a professional painter for work above 12 feet, homes with extensive architectural details, or if you're uncomfortable with the precision required around expensive trim work.
