How to prime walls for painting?

To prime walls for painting, follow these steps:

1. Choose a primer: Choose a primer that is suitable for the type of wall surface you are priming and the type of paint you will be using.
2. Prepare the wall surface: Make sure the wall is clean, dry and free of any dust or debris. If necessary, repair any cracks or holes.
3. Apply the primer: Using a paint roller or brush, apply an even coat of primer to the wall surface, covering all areas completely.
4. Wait for the primer to dry: Allow the primer to dry completely, following the manufacturer’s recommended drying time.
5. Sand the surface: Lightly sand the surface to remove any rough spots or drips.
6. Apply a second coat if necessary: If the primer has soaked into the wall and you can still see the original color, apply a second coat of primer.
7. Clean up: Clean your paint tools and store them properly for later use.

Note: If you’re priming over a very dark color or a glossy surface, you may need to use a stain-blocking primer to prevent the color from bleeding through the final paint coat.
