How Many Coats of Wall Paint Do You Need?
Most interior walls require two coats of paint to achieve even colour, good coverage and long-lasting results.
However, the exact number of coats depends on the wall surface, paint quality, colour change and preparation.
- Most walls: 2 coats
- Dark colours or patched walls: 2–3 coats
- New plaster: primer + 2 coats

Why two coats of wall paint are usually recommended
Applying two coats of wall paint:
- Improves colour depth and consistency
- Covers patchiness and roller marks
- Increases durability and washability
- Ensures a uniform finish
One coat is rarely sufficient for a professional-looking result.
When one coat of wall paint may be enough
In some situations, a single coat may be sufficient:
- Painting over a similar colour
- Using high-opacity paint
- Touch-ups on previously painted walls
Even in these cases, a second coat often improves the overall finish.
When more than two coats may be needed
Additional coats may be required if:
- Painting over dark or bold colours
- Covering stains or patched areas
- Walls are very porous
- Paint is heavily diluted
Applying thin, even coats produces better results than one thick coat.
Does wall paint finish affect the number of coats?
Yes, the finish can influence coverage:
- Matt paint: Often needs two coats for uniform colour
- Silk paint: May highlight patchiness if coverage is uneven
- Eggshell paint: Typically covers well but still benefits from two coats
Regardless of finish, proper preparation helps reduce the need for extra coats.
Should you use a primer before painting walls?
Primer can reduce the number of paint coats needed by:
- Sealing porous surfaces
- Improving adhesion
- Preventing colour bleed
Primer is recommended for new plaster, bare surfaces or major colour changes.
How long should you wait between coats of wall paint?
Most interior wall paints require:
- 2–4 hours between coats
Always follow the manufacturer’s guidance, as drying times vary by formulation and conditions.
