Can You Paint Over Dirty Walls?

In theory, you can paint over dirty walls, but if you’re asking whether you should, the answer is a definitive no.

If you try to apply paint over walls with dust, dirt, and grime on them, the paint is going to have a much harder time sticking and staying where you want it. For a paint job that you’re proud of, the walls need to be clean before you move forward.

Take time to clean the walls to ensure your paint adheres properly. If you don’t, the paint may not adhere to the walls and can peel off. This might result in the need for another paint job much quicker than if you had gone ahead with a bit of cleaning first.

You might still be wondering, “Should I pressure wash my house before painting?” The answer to this is generally yes, although there are alternatives you can choose instead. When you pressure wash a house before painting, you get a clean canvas for the paint and the promise of a job well done.

Most professional painting companies will handle this process for you as part of their services. But make sure you’re aware of what to expect from your painters so you know what is your responsibility and what they will do in order to be ready for painting. 

Pressure Washing: Pros and Cons

To give you an idea of whether pressure washing is right for you, we want to go into the benefits and drawbacks of this cleaning option.

One of the great things about pressure washing is that it is amazingly efficient at cleaning. It can cut through mildew, mold, and stains to give you a clean surface for paint to adhere to. With other methods, the process may take longer or be more complex.

On the other hand, professional expertise is needed to ensure pressure washing is done right. If a novice tries to pressure wash a home, it could lead to surface damage, which you want to avoid. Water intrusion is also possible and highly problematic, so steps should be taken to avoid it.

Understanding the Difference: Pressure Washing vs. Power Washing

Pressure washing and power washing are similar, but do have some distinctions you should be aware of. Both use pressurized water to remove dirt and grime from surfaces like walls. However, pressure washing uses cold water, while power washing uses hot water.

Pressure washing is a great choice and less expensive than power washing. It’s excellent for standard cleaning and is the primary method used by most painting companies.

Power washing tends to be better for heavily soiled surfaces and is a harsher process meant for driveways, garage floors, and sidewalks.

With that being said, pressure washing is the way to go for routine prep prior to painting a home.

Hand Washing: A Manual Cleaning Alternative

Do you have to pressure wash a house before painting? No. There is an alternative that you can use if you prefer.

Instead of working with a pressure washer, you can manually clean the surface on your own. Make sure you have the right tools, such as house and siding cleaner and a cleaning sprayer to make the process as simple as possible. You could also use a hose with a spray nozzle. 

Since this is a gentler and more controlled cleaning method, you’re less likely to cause damage to the surface of your home. It will take much longer than pressure washing, but there’s no need to bring in professionals for the process. It’s up to you whether that meets your needs.
