Eli5: Why both primer and paint?
In: 6
Primer is really good at sticking to things. It’s better than sticking to things than paint is. The best part about that, is that primer itself is pretty sticky too, like double sided tape. So when you put the paint on the primer, it’s pretty well stuck.
Also, sometimes you want to paint something, but it might already be one color. When you pick out a paint color at the store, it’s only really that color when you paint over the same kind of background color, and the closer you can keep that background color, the better. That’a where primer comes in: it’s all one color, you can easily see the areas that you might need a little more of it to make them all the same, and if you let it all dry, it makes your paint look the way it’s supposed to.
