Techniques for Painting Over Dark Colours

Professional Painter | January 28, 2025

At Dunbar Painting, we know that painting over dark colours can be a challenging task, especially when transitioning to lighter shades or trying to achieve a smooth, uniform finish. Since dark paint colours tend to bleed through new layers, painting over dark colours requires specific techniques to ensure proper coverage and durability. That is why we have compiled some information about the different techniques for painting over dark colours.

How to Effectively Paint Over Dark Colours

1. Prepare the Surface

Preparation is the key to success when painting over dark colours. Begin by cleaning the surface to remove dirt, grease, and dust, as these can affect the new paint’s adhesion. Sand the surface lightly to create a rough texture, which will help the new paint bond effectively.

2. Use a Quality Primer

Since primers act as a barrier between the old and new paint, using a high-quality primer can help prevent the dark shade from bleeding through. Make sure to choose a primer designed for heavy coverage, such as those labelled “stain-blocking” or “high-hide”. For extremely dark colours, a tinted primer that closely matches the new paint colour can further enhance coverage. Apply one or two coats of primer, allowing it to dry completely between applications.

3. Opt for the Right Paint

When painting over dark colours, selecting the right paint makes a significant difference. High-quality paints with good opacity and coverage are best suited for this task. Look for paints labelled “one-coat coverage” or “ultra-hide” to reduce the number of layers required. For light colours, such as whites or pastels, you may need multiple coats to achieve the desired finish, even with the best products.

4. Layer with Proper Techniques

Applying the paint correctly is crucial for even coverage. Use a high-quality roller for large, flat areas and brushes for corners and edges. Start with a “W” or “M” motion when rolling to distribute the paint evenly before filling in the gaps. Allow each coat to dry completely before applying the next layer. Multiple thin coats are preferable to one thick coat, as this helps prevent drips, streaks, and uneven patches.

5. Apply the Finishing Touches

After achieving full coverage, focus on the final touches to enhance the finish. Check for any missed spots or streaks and touch them up with a small brush. If the surface looks uneven or textured, lightly sand between coats to create a smooth result. Finally, consider sealing the paint with a clear topcoat for added durability and a polished look, especially in high-traffic areas.
