Wrong Color in a Section
This is the most common mistake and the easiest to fix. Acrylic paint is opaque — meaning you can paint over it with the correct color once the first layer is dry.
- Wait for the wrong color to dry completely — usually 10-15 minutes
- Apply the correct color directly on top — one coat is usually enough
- If the underlying color shows through — apply a second coat after the first dries
Light colors over dark may need 2-3 coats. Dark colors over light typically need just one. The final result will look perfect.
Paint Over the Lines
Went into a neighboring section? Same solution — wait for it to dry, then paint the correct color over the overlap. The key is patience. Do not try to wipe wet paint as it will smear and make things worse.
No experience needed to fix mistakes — acrylic paint makes corrections forgiving.
Thick Blobs or Uneven Coverage
Applied too much paint and it looks lumpy? Let it dry completely, then gently sand the area with very fine sandpaper (400 grit). Apply a thin, even coat of the correct color on top. The result will be smooth and even.
Paint Dried in the Pot
If a paint pot has thickened, add 1-2 drops of water and stir with a toothpick. The paint should return to a creamy, smooth consistency. Do not add too much water — you want paint, not watercolor.
Smudged a Wet Section
If you accidentally smudged wet paint with your hand or arm, let it dry first. Then paint over the smudged area with the correct color. To prevent future smudges, always paint from top to bottom and from left to right (or right to left for left-handed painters).
Prevention Tips
- Always double-check the number before applying paint
- Keep a paper towel handy — dab minor wet mistakes immediately
- Work in one direction — prevents smudging completed sections
- Close paint pots after use — prevents drying
- Use a magnifying glass for tiny numbers
Every painter makes mistakes — even professionals. The beauty of paint by numbers is that acrylic paint makes corrections simple and invisible. Joined by thousands of painters worldwide, you will learn that mistakes are just part of the creative process.
