Ever tried painting over dark colours and ended up frustrated with streaks, shadows, or that stubborn base showing through?
If you're looking to brighten up your space, switching from dark to light can be a challenge. Without the right technique, the original colour can linger under layers of new paint, leaving your walls looking uneven.
But don’t worry—with a bit of preparation, patience, and the right steps, painting over dark colours can actually be a breeze. This guide will take you through each step for getting full coverage when transforming dark walls. Ready to create a fresh, new look?
1: Start with the Right Supplies
Having the right tools for the job will save you time, money, and hassle in the long run. Here’s what you’ll need to make painting over dark colours as smooth as possible:
High-quality paint: Go for a high-quality latex or acrylic paint that’s durable and has good coverage.
Primer: Essential for covering dark colours.
Paint roller and brushes: A roller with a thick nap for textured walls and a smoother roller for flat surfaces.
Sandpaper (120–220 grit): For smoothing out surfaces.
Painter’s tape: For clean edges.
Drop cloths: To protect your floors and furniture.
Putty and putty knife: For small repairs if needed.
2: Prep the Wall Surface Properly
Painting over dark colours is all about prepping the surface right from the start. Taking a few extra steps here will make the entire process go much more smoothly.
Clean the Wall
Start by cleaning your wall. Dark walls may have dust, grime, or even old fingerprints, which can affect how the new paint sticks. Use a mild detergent and water, then let it dry completely before moving on to the next step.
Sand and Repair
If your wall has any chips or imperfections, now is the time to repair them. Sanding will also help the primer stick to the surface better. Use a fine-grit sandpaper, like 220, and gently smooth out any rough patches. Once you’ve sanded, wipe the wall down with a damp cloth to remove any dust.
Prime the Wall
Priming is essential when painting over dark colours, as it provides a blank slate for your new paint. Without primer, dark colours can bleed through, leaving an uneven look.
Choose a high-quality primer: A stain-blocking or tinted primer works best to hide dark colours. If you're transitioning to a very light colour, a white primer will help.
Apply an even coat: Use a roller for large areas and a brush for corners. Let the primer dry fully before moving on—don’t rush this step!
3: Choosing the Right Paint for Full Coverage
When painting over dark colours, selecting a high-quality paint can make all the difference. Dark shades require a paint with excellent opacity to prevent bleed-through.
Consider a Paint-and-Primer Combo
Some paints come with primer included, which can add an extra layer of coverage. While this may not replace a dedicated primer coat, it can enhance coverage and reduce the number of top coats you’ll need.
Opt for Matte or Satin Finishes
A matte or satin finish can help disguise any remaining imperfections on the wall, making them ideal when transitioning from dark to light colours. High gloss finishes can highlight even small irregularities, which may not be ideal if you’re trying to hide a dark base.
4: Apply Thin, Even Coats
The trick to full coverage when painting over dark colours is applying multiple thin layers. While it may seem quicker to slap on a thick coat, this approach often leads to streaking and uneven coverage.
Start with the Edges
Using a brush, carefully paint along the edges of the wall, especially around doors, windows, and corners. Getting even coverage in these areas can make the overall finish look more polished.
Use a Roller for Large Areas
After the edges are painted, switch to a roller for the larger sections. Start at the top of the wall and work down in a “W” pattern to avoid streaks. Roll slowly and with light pressure, which helps the paint spread evenly and reduces drips.
5: Let Each Layer Dry Completely
Patience is essential! Allowing each layer to dry fully before adding the next one ensures that the colour remains even and no patches show through. Drying times will depend on your specific paint, so refer to the manufacturer’s instructions.
6: Inspect and Touch Up if Necessary
Once you’ve completed your layers, take a step back and inspect the wall for any shadows or streaks. If you notice any areas where the dark colour is still visible, go back in with a small brush or roller and add a touch-up coat. This final touch can make all the difference between a professional-looking finish and an uneven wall.
Common Mistakes to Avoid When Painting Over Dark Colours
Skipping the Primer: Primer is a must for painting over dark colours, so don’t skip this step.
Using Low-Quality Paint: Cheap paint may seem budget-friendly, but you’ll end up needing more coats, costing more in the long run.
Applying Too Much Paint at Once: Multiple thin layers provide a more even coverage than one thick layer.
Ignoring Drying Times: Allowing each coat to dry fully will give you a smoother, more professional finish.
