How do I paint a bathroom properly?

Proper bathroom painting requires moisture-resistant materials and thorough surface preparation to prevent peeling, mold, and water damage in Ottawa's humid climate.

Surface preparation is critical for lasting results. Start by cleaning all surfaces with TSP (trisodium phosphate) to remove soap scum, mildew, and grease. Sand any glossy surfaces lightly to help the new paint adhere. Fill holes and cracks with paintable caulk or filler, and remove any loose or peeling paint completely. In older Ottawa homes, test for lead paint before sanding if the house was built before 1978.

Choose the right paint and primer for bathroom conditions. Use a high-quality primer designed for bathrooms - this creates a moisture barrier and helps the topcoat adhere properly. For the finish coat, select a paint specifically formulated for high-humidity areas, typically a semi-gloss or satin finish acrylic latex paint with mildew-resistant properties. These finishes are easier to clean and more resistant to moisture than flat paints.

Proper ventilation during and after painting is essential, especially during Ottawa's humid summers. Run your exhaust fan continuously while painting and for several hours afterward. Open windows when weather permits to improve air circulation. Apply thin, even coats rather than trying to cover everything in one heavy application - this prevents drips and ensures better adhesion.

Pay special attention to high-moisture areas like around the tub, shower, and sink. Use paintable caulk to seal gaps between the wall and fixtures before painting. Consider using a moisture-resistant primer in these areas even if the rest of the bathroom doesn't require it.
