First of All, What Is Paint Primer?

When Isn’t Paint Primer Necessary?

If youve never painted something before, you probably think every surface needs to be primed before painting.

This issort oftrue, but there are definitely exceptions to this rule.

Also, if you are painting dark over light, primer is not typically necessary.

For example, Davis says, Flat paintwill stick to flat paint."

And if you’re painting latex paint on top of existing latex, then you don’t need primer.

These are often called “paint and primer in one.”

When Do You Absolutely Need To Use Primer?

If you’re unsure, you should always prime a surface before painting because most surfaces do need priming.

There are very specific instances though where you should definitely brush on the primer.

Choosing the right kind of primer is equally important.

The clarity of color can vary depending on what you are going over.

Ensuring the paint can endure heat, cold, and other environmental elements is essential.
