Primer is not supposed to look streaky or have visible drip lines. While primer does not need to completely cover old coats of paint in order for your new paint to go on flawlessly, primer should be applied in a uniform manner. Make sure to cover the surface with an even coat of primer, reloading your roller often as you go. When covering dark colors of stained walls, it may be necessary to apply 2 coats of primer.
How Should Primer Look Before Painting?
Before you begin applying coats of finish paint, primer should form an even coat of paint over the existing surface. It should not have streaks, drip lines, or large variations in coverage. An uneven or streaky coat of primer may result in an uneven paint job.
- Primer should have an even, uniform appearance.
- There should not be streaks, drips, or uneven coloration to your primer coat.
- It’s okay for the previous paint color to slightly show through primer.
Although it should provide a fairly uniform look prior to painting, primer does not need to completely cover old paint colors. If you are painting over a dark color, it may still show through 2 coats of primer. However, the primer will still serve as an excellent surface for your final paint color to adhere to. The finish coat will hide the old paint color.

How Do You Prevent Streaky Primer?
To prevent your primer from having a streaky look, start with a high-quality primer. Then, use a roller with ⅜-inch nap to apply it to walls and ceilings. Apply the paint evenly. You will need to reload your roller often, but this will ensure even coverage. If you are seeing roller marks on your wall, odds are you’re not using enough paint.
- This water-based primer is great for providing even coverage and hiding stains.
- Apply primer with a roller with a ⅜” nap.
- Apply the primer evenly. If there are streaks and roller marks, you need to add more paint to your roller.
- Use a second coat of primer on surfaces where a single coat doesn’t provide even coverage.
If primer appears streaky, uneven, or does not give coverage after one coat, then it’s time for another layer of paint to hide those roller marks. Porous surfaces, such as new drywall, soak up paint. It’s important to provide an evenly primed surface for your finish paint to stick to. This will result in a beautiful finished painting project.
Does Primer Need to Cover Old Paint?
Primer does not need to completely cover old paint in order to be effective. It’s not necessary to apply coats of primer until you achieve a white “blank canvas.” Primer acts as a barrier that allows the new paint to stick and provide optimal coverage. Even if you can still see shades of the old color through the primer, it’s still doing its job.
- Primer does not need to completely hide the old paint in order to work properly.
- Even if you can still see hints of the old paint color through primer, new paint will stick to the primer and provide good coverage.
- In the case of dark-painted or stained walls, apply a second coat of primer to ensure your wall is properly primed.
Although primer does not need to return a room to blank white to be effective, it’s still good to apply a second coat of primer during tough repainting jobs. If you are transforming a dark-painted wall into a light wall, apply 2 coats of primer before repainting with your light color.
How Many Coats of Primer Do You Need?
When repainting ceilings and light walls with minimal stains or patches, one coat of primer is usually sufficient. If you are painting a new wall (such as new drywall), a stained wall, or a dark-painted wall, apply 2 coats of primer.
- 1 coat of primer is sufficient for light-painted walls and ceilings without stains.
- 2 coats of primer is best for new, repaired, stained, or dark-painted surfaces.
- If your first coat of primer is streaky or uneven, always apply a second coat.
Remember, it will never do harm to apply a second coat of primer. If you can see roller marks or brush strokes on the wall, or if the primer is streaky, apply a second coat regardless of the surface beneath. This will result in a better-finished product.
How Long Should You Wait Between Primer Coats?
Allow at least 24 hours for your primer to fully cure before painting over it. This rule applies whether you are applying a second coat of primer or a coat of colored paint. Primer needs 24 hours to cure so that it sticks to the wall surface and provides the ideal surface for the next coat of paint to adhere to.
- Wait 24 hours between coats of primer.
- Primer needs 24 hours to cure and provide the best surface for new paint.
- Painting over primer too soon will result in peeling, bubbling, and deteriorating paint.
Even if your primer seems dry to the touch, wait the full 24 hours before applying a second coat. Painting over primer too soon leads to bubbling and peeling paint. It’s best to wait a full 24 hours before applying that fresh coat of paint in order to create the most durable paint job.
Is Primer Supposed to be See-Through?
Although it’s okay to be able to see hints of the old color through primer, your primer should not have a streaky or uneven appearance. In order to set yourself up for success with primer:
- Use a high-quality primer.
- Apply primer to walls and ceilings with a ⅜” nap roller.
- Spread primer evenly. It should be streak-free and individual roller marks should not be visible.
- Apply 2 coats of primer on new walls, stained walls, and dark-painted surfaces.
- Wait 24 hours between coats of primer.
By following these rules, you’ll get even coverage with your primer. The end product will be an incredible paint job with smooth walls that hide any previous paint colors.
