Repainting a room that currently has dark or bold colours can feel challenging. Many homeowners wonder if they can simply paint over the dark shade with lighter paint or if a primer is always required. The truth is that while it is technically possible in some situations, using primer almost always leads to better coverage, richer colour, and fewer coats. Here is everything you need to know before refreshing your walls.
Is it possible to paint over dark colours without primer?
Yes, it is possible, but it is rarely recommended. Without primer, dark colours often bleed through lighter paints, causing patchiness and uneven results. You may find yourself using three or more coats to hide the underlying colour.
Using a quality primer helps block the darker pigment and allows the final colour to appear clean and accurate. You can find dependable primers in Randall’s Paint Collections
When can you skip primer over dark colours?
You may be able to skip primer when:
- You are repainting with another dark or medium shade.
- You are using a paint and primer in one designed for higher coverage.
- The existing paint is in excellent condition with no stains or sheen differences.
Even in these cases, using primer still improves final coverage and reduces the number of coats needed.
Why is primer important when covering dark walls?
Primer helps:
- Block stubborn pigments and prevent colour bleed
- Create a uniform surface with consistent porosity
- Improve adhesion for long-lasting results
- Reduce roller marks and flashing
- Save time and product by reducing extra coats
Skipping primer often means spending more time and money layering paint to achieve the same result.
What type of primer should you use over dark colours?
The most effective option for covering dark walls is a high-hide, stain-blocking primer. These primers are formulated to neutralize bold pigments and create an even base for lighter shades.
A gray-tinted primer is often recommended when switching from dark to light colours because it balances the transition and provides excellent coverage.
Randall’s carries a wide selection of primers specifically made for challenging colour changes.
How many coats of paint do you need after priming?
Typically, you will need one to two coats of your final colour after applying primer. This ensures your new colour appears rich, true, and streak-free.
Without primer, you may need three or more coats, especially if switching from dark colours like navy, charcoal, forest green, or burgundy to lighter neutrals.
How do you prep dark walls before painting?
Proper preparation guarantees better results. Follow these steps:
-
Wash the walls to remove dust and oils.
-
Sand glossy surfaces lightly to improve adhesion.
-
Patch holes and repair imperfections.
-
Apply a high-hide primer.
-
Allow primer to dry completely before painting.
Good prep work prevents peeling, uneven absorption, and unnecessary touch-ups.
What tools work best for painting over dark colours?
Use:
- A high quality roller with the correct nap length for your wall texture
- An angled brush for cutting in
- Paints with strong opacity
- A primer specifically formulated for colour blocking
Randall’s specialists can help you choose the best roller, brush, and product for your project.
Is it better to hire a professional for large colour changes?
Large spaces, high ceilings, or dramatic colour changes can be time-consuming. Professional painters have the experience and tools to deliver smooth, flawless coverage with fewer coats.
