Eli5: Why both primer and paint?
In: 6
Primer grips to any surface and makes a more uniform bond for the paint. In practical terms, of you want to paint your kitchen, for example, you might not realize it, but close to the stove the wall is coated in years of grease and sauce splatter. This grease will eventually show through your paint, the paint might bubble or flake off as well, so if you Prime the walls to a uniform coating, the paint will sit on top of the primer and result in a longer lasting result. Speaking from experience, I’m just a dad who learns the hard way.
