When it comes to painting, one of the most common questions homeowners ask is: “Do I really need two coats of paint, or will one coat do the job?” While one coat may seem quicker and cheaper, the reality depends on your surface, colour choice, and goals. Here are the pros and cons, explained by the experts.
1. Can one coat of paint ever be enough?
Yes—under certain conditions. If you’re repainting a wall with the same or very similar colour, using high-quality paint, and applying it with the right tools, one coat may be sufficient.
2. What are the pros of using only one coat?
-
Saves time: Faster completion for small projects.
-
Lower cost: Uses less paint.
- Good for touch-ups: Perfect for covering small areas or quick fixes.
3. What are the cons of relying on just one coat?
-
Inconsistent coverage: Roller marks, streaks, or thin spots may show.
-
Poor colour accuracy: The final shade may look uneven.
-
Durability issues: One coat often wears out faster.
- Difficult with colour changes: Dark-to-light transitions almost always need more coats.
4. When is one coat usually not enough?
- Switching from dark to light colours
- Covering stains or patched areas
- Painting new drywall or bare wood (always prime first)
- Rooms with high traffic, like hallways and kitchens
5. Do paint-and-primer-in-one products make one coat possible?
Sometimes. High-quality paint-and-primer-in-one products can improve coverage, but in most cases, two coats are still recommended for durability and a flawless look. Browse Randall’s paint collection
6. How do I know if I need a second coat?
- Check for streaks, roller marks, or patchiness once the first coat dries.
- If the old colour still bleeds through, apply another coat.
- Run your hand lightly across the wall—if the finish feels uneven, add a second coat.
7. Does one coat last as long as two?
No. Even if coverage looks okay at first, one coat usually wears down faster. Two coats provide a stronger, more washable surface—especially in high-traffic areas.
8. Should I hire a professional for a one-coat project?
If you’re aiming for a flawless finish in one coat, professionals have the skills, tools, and techniques to get it right. Use our Painter Order Form
9. How does primer affect the number of coats needed?
Primer can reduce the number of topcoats by creating a smooth, even base. For major colour changes or new surfaces, primer is essential. Learn more from our services team

While one coat of paint may be enough in rare situations, two coats are almost always worth the extra effort. They ensure even coverage, durability, and a long-lasting, professional look.
