Most new surfaces, such as wood, masonry, fresh plaster, or drywall, need a primer to seal the surface and cover minor imperfections. Using the right primer on the surface you’re painting can really make a difference in your finished project.
When Do You Prime?
- When you are painting over a bare surface such as new wood, new drywall or any other surface that has never been painted before.
- When you are painting a light color over a dark color or using a very dark color.
- When your surface is porous and does not pass the water test.
The water test is when water that is splashed on the surface soaks in instead of rolling off.
Paint will soak in the same way as water, so the surface needs to be sealed with a primer.
- When you have a problem surface, i.e.:
- Your surface is uneven or badly deteriorated.
- Your surface is stained with ink, dirt, crayon marks, grease, rust, smoke residue, or is water-stained, etc.
- You are painting over wallpaper. Many wall coverings contain dyes that can bleed through
- Your surface has water stains on the walls and/or ceilings.
- When your surface has been stripped or is worn down to the original surface material.
