Is it really worth the effort and expense to prime before you paint? Absolutely. A primer preps the painting surface and seals any stains so that the paint adheres well, and you'll get the smoothest, cleanest finish possible.

What happens if you don't use primer before painting?

If you skip priming, you risk peeling paint, especially in humid conditions. Moreover, the lack of adhesion could make cleaning more difficult months after the paint has dried. You may find the paint wearing off as you're trying to wipe off dirt or fingerprints.

What is the purpose of using primer before painting?

Think of paint primer as a base coat that creates the foundation for a flawless paint job. From cutting down the number of coats you'll need, to protecting your paint from wear over the years, priming actually makes your job easier in the long run.
