Choosing the Right Paint for Kitchens and Bathrooms

Interior paint comes in a range of formulations, and the wrong one in a high-moisture environment like a kitchen or bathroom creates problems quickly. Understanding the key variables makes the difference between a finish that lasts and one that starts peeling within a year. For prep and application technique, see Interior Painting Tips: How to Get a Professional Finish.

Sheen Level Matters

In high-humidity spaces, use at least a satin or semi-gloss finish. Flat and eggshell paints are porous enough to absorb moisture, which promotes mould growth and makes surfaces difficult to clean. Satin is the minimum for most bathrooms; semi-gloss is better in areas with direct water contact (around the shower, above the tub).

The tradeoff with higher sheen is that surface imperfections are more visible. Proper prep — filling, sanding, priming — is even more important when using semi-gloss.

Mould and Mildew Resistance

Many paint manufacturers offer kitchen and bath specific formulations with built-in mildewcide. These are worth the modest premium in any bathroom that doesn't have excellent ventilation. However, no paint prevents mould on its own — adequate ventilation and moisture management are the first line of defence.

For a bathroom with a ventilation fan that runs properly and dries quickly after use, a quality satin-sheen paint with mildewcide additive will last well. For a consistently damp bathroom with poor airflow, address the ventilation issue first, or the best paint in the world will fail prematurely.

Primer in Bathrooms

Use a dedicated primer before painting in bathrooms — particularly oil-based primer on areas with staining, or shellac-based primer to seal nicotine, water stains, or heavy odours. A quality primer creates a uniform, adhesion-friendly surface that dramatically extends the life of the finish coat. This step is especially critical during a full bathroom renovation where surfaces have been recently opened up.
