- By sealing the original surface, primer stops paint from soaking into it. So you don’t need to keep adding extra coats.
- It hides any joints, seams, blemishes or other marks to make sure that they don’t come through the paint.
- It’s typically white or other neutral colours, which helps to make sure that your paint colours show true.
- If the final colour is much lighter than the original, adding a small amount of pigment to the primer will bring it closer to your final paint colour and help to prevent the original surface from coming through.
Helps it stick
- When painting on top of previous coats that are shiny and glossy, paint can often struggle to stick because it requires more texture to hold onto.
- Adding a couple of coats of primer will help your topcoat stick to surfaces with a high sheen, even if you don’t give them a light scuffing with sandpaper first.
