Question 2

Why should I prime a wall before painting?

Accepted Answer

Priming your wall before painting offers many benefits, including better adhesion for a more uniform appearance, better sealing for a smooth and consistent topcoat on porous surfaces, improved color coverage with fewer coats, enhanced durability to resist cracking, peeling, and moisture damage, and a long-lasting finish. For more useful tips and helpful advice, read our guide on how to prime a wall.

Question 3

How do I choose a paint primer?

Accepted Answer

Choosing the right paint primer depends on surface type, paint color, and conditions. Use a latex or water-based primer on new drywall, an oil-based primer on bare wood, a rust-inhibiting primer on metal, and a bonding primer on glossy or slick surfaces. You'll want a white or tinted primer for light paint colors, a gray primer for bold or dark colors, and an off-white or light gray primer for pastels. Some conditions require specialized primers, like a mold-resistant primer for high-moisture areas, or a stain-blocking primer for smoke, water, or heavy stains.

Question 4

How many coats of primer should I put on before painting?

Accepted Answer

The right number of coats depends on the surface condition and color change. One coat is usually enough for most walls in good condition. However, consider an extra coat when covering a dark color with a light color (or vice versa), when covering a porous surface like new drywall or bare wood, and when sealing stains or repairs.
