Do I always need to use primer before painting?

Primer is essential on new drywall, bare wood, and when making drastic color changes. It is optional on previously painted surfaces in good condition when using paint-and-primer products.

Should I tint my primer?

Yes, tinting primer toward your topcoat color improves coverage and can reduce the number of topcoats needed, especially with deep or vibrant colors.
