Why Surface Preparation is Important Before Painting

Tips for Painting About to paint your home? Before you grab those brushes and rollers, take some time out for surface prep. Full surface preparation includes cleaning, repairing, sanding, patching, masking and priming. The process may be time-consuming, but it’s an essential step. An estimated 80 percent of paint failures are due to improperly preparing the surface.

Here’s why surface preparation is important before painting:

Paint adhesion

You might think your wall is clean, but even if it looks spotless it probably still has dust, dirt and mold that will prevent your paint from properly adhering. Make sure your wall is dry before you paint it, as the paint will not adhere well to a wet or damp surface.

Even paint

If you fail to prime your surface before painting it, your paint will look uneven in shade. Sealing and priming your surface will help the paint absorb more evenly across the entire wall.


Damp walls, dirt, cracked surfaces and more can shorten the life of even the highest-quality paint job. Take the time to prep to make sure that your paint lasts longer.


Tempted to skip surface preparation, even though you now know all of the above? Don’t do it. Once the paint dries, your seemingly beautiful paint job will show uneven surfaces, dirt buildup and other imperfections. Take the time to prep for a flawless look.

    That’s a good point that walls may look clean but might still have dust or mold or other particles clinging to them. I imagine it’s a lot more effective to thoroughly clean your walls before painting them. My husband and I have a renovation that needs a good new coat of paint. We’ll have to get professional painters to come in and give it the attention that it needs.

    You made a great point about durability and how prepping will make the paint last longer. My husband and I are looking for a commercial painter that can help his company repaint the rooms in their building. We will keep these tips in mind as we search for a professional that fits their needs best.
