How to Paint Over Dark Walls with Light Colours (Without 5 Coats of Paint)

If you're ready to brighten up your home by covering a dark wall with a lighter colour, you're not alone. Many UK homeowners are shifting away from bold tones like navy, forest green, or charcoal and returning to softer, more neutral palettes. But painting over dark walls can be tricky. Without the right preparation, it’s easy to end up with patchy coverage, visible brush strokes, or five unnecessary coats of paint. Here’s how to do it the smart way.

Use a Quality Primer

Priming is the most important step when going from dark to light. A high-quality primer blocks the original colour and gives your new paint something to grip. Look for a stain-blocking or high-hide primer—preferably one that can be tinted to a shade close to your top coat. This reduces the number of coats needed and helps prevent the old colour from bleeding through.

Choose the Right Tools

Use rollers with a medium to thick nap, especially if your walls have texture. A high-quality angled brush is essential for clean edges and corners. Budget tools may leave streaks or lint behind, so invest in reliable brands for a smoother finish.

Apply Paint in Thin, Even Coats

Once primed, apply your chosen paint in two light coats instead of one heavy one. Work in small sections, keeping a wet edge to avoid lap marks. Allow proper drying time between coats—rushing this step can cause streaks and uneven sheen.

Use the Right Paint

Look for paints labelled as 'high-hide' or 'one-coat coverage,' especially those from reputable brands. Lighter colours with strong pigment bases, like warm whites and creams, usually perform better when covering dark tones.

Final Touches

Once your second coat is dry, step back and inspect the room in natural light. You may need a third coat in high-contrast areas or if you skipped priming. Touch up with a steady hand and enjoy your transformed space!
