What kind of paint holds up best in a Vancouver bathroom with all the moisture we get?
Bathrooms in Metro Vancouver deal with a double moisture challenge - steam from showers on the inside and our generally humid coastal climate on the outside. The best choice is a 100% acrylic latex paint in a satin or semi-gloss finish. These sheens repel moisture better than flat or eggshell and are much easier to wipe down when condensation builds up.
Look for paint labelled as mildew-resistant or containing antimicrobial additives. Several major brands available at Vancouver paint suppliers offer bathroom-specific formulas designed for high-humidity rooms. This matters more here than in drier parts of Canada because our mild, wet winters mean bathroom moisture takes longer to evaporate.
Proper ventilation is just as important as the paint itself. If your bathroom fan is undersized or venting into the attic rather than outside, even the best paint will eventually develop mould. The BC Building Code requires mechanical ventilation in bathrooms, so make sure your fan meets current standards and actually exhausts to the exterior.
Before painting, prep the walls thoroughly. Any existing mould spots should be treated with a mould-killing primer - painting over active mould just traps it underneath. Sand glossy surfaces lightly so the new paint adheres properly, and use a moisture-blocking primer on drywall that has never been painted.
As a next step, have a painter assess your bathroom ventilation during the quoting process. A good contractor will flag ventilation problems before they start, saving you from premature paint failure down the road.
