How Long After Pressure Washing Can You Paint?

If you’ve decided to undertake a large exterior paint project, then it only makes sense to make sure that you give the surface of your chosen building a pressure wash prior to starting the paint job.

Not only will it help to get rid of dirt, debris, and flaking paint, but it will also help to ensure that the surface is smooth, which will ensure that the paint applies evenly. In general, you will usually need to wait for a few days after pressure washing, as this will ensure that the walls have been able to completely dry from the wash.

However, there are some additional factors that can contribute to how long you should wait to paint after pressure washing – let’s take a look at some of them below:

  • The moisture: Generally speaking, you’ll want to wait for at least three days before you begin painting, as porous surfaces such as brick and wood will need time to dry and allow all moisture to evaporate from its surface. If you paint too soon after pressure washing, the damp surface will be unable to properly bond with the paint, which can lead to imperfections and the need for a new paint application.
  • The weather: The next factor that plays a role in deciding how long you’ll need to wait after pressure washing is the weather conditions. Humid weather and high temperatures will mean that there is more moisture in the air, which means that it will take longer for your walls to dry after the pressure wash.
  • The type of paint: Last but certainly not least, the next factor that you should take into account is what type of paint you have decided to use. Oil-based paints will require a waiting time of at least three days, as they cannot be applied to damp surfaces, while latex-based paints often only need a waiting time of 24 hours, as they are able to adhere to slightly damp surfaces without any problems.

Do I need to wash outside of the house before painting?

One of the biggest mistakes you can make when embarking on the journey of repainting the exterior of your home is to overlook the preparation process. Before you even think about beginning to paint the exterior of your home, you should first ensure that you spend a good amount of time preparing the walls so that they are ready for the paint to be applied.

Ideally, you should ensure that your exterior walls have been thoroughly cleaned and rid of any debris and dirt, while also taking the time to carefully cut away any plants or tree branches that are overhanging the walls and obstructing access.

Usually, the best course of action is to use a power washer that will be able to do the hard work for you and blast away large amounts of the grime from the surface of the walls. Although, if there are certain spots that just won’t seem to get clean, you might also find yourself needing to clean parts of your exterior walls by hand.

In general, many people choose to mix water and bleach together and then apply the mixture to the stubborn areas of the wall, before scrubbing the remaining stains and dirt off with a rough sponge or wire brush. In addition to this, you should also make sure that you fill in any holes or cracks that may be present in the surface of the walls, as this will help to ensure that the paint has a smooth surface to go on.

With all of this combined, it’s easy to see why taking the time to properly prepare the outside of your house is so important (not just pressure washing) as it will ultimately allow for a smooth, even, and uniform paint job that will look exactly the same as if you were to have hired a professional!

Should I pressure wash my house before painting?

Whether you’ve recently moved into a new house and have decided to completely revamp its exterior appearance, or you’ve simply decided to spruce up your current home, a paint job is the easiest way to make your home look bright and inviting. On top of that, it’s also a surefire way of boosting its curb appeal!

Pressure washing is one of the best ways that you can prepare exterior surfaces (such as the outer walls of your home) for a paint job, as it will help to rid the surface of dirt and debris prior to painting.

Though a pressure wash will usually only take a few hours to complete, it is still generally considered that you are supposed to give the walls a small break in-between pressure washing and painting, as this will allow the exterior walls to fully dry from the wash and, in turn, prevent the chances of patches, cracks, peeling and additional problems from occurring after the paint has dried.
