One of the most important steps in preparing your home for new paint is pressure washing, which will remove dirt and grime from the exterior of your home. Pressure washing will not only make it easier for your fresh paint to adhere to the surface, but it’ll also help you avoid expensive re-paint jobs later on down the line. In order to get started with this easy process, follow these simple steps!

Rent your pressure washer

Most home improvement stores, such as a professional painting, will rent you the equipment needed to conduct this task for a small fee. You can rent a pressure washer anywhere, depending on the model. Be sure to check with your local store for availability.

Mix your chemicals

The chemical mixture you’ll need to create depends on the type of paint you plan to use, so be sure to ask before you buy! For latex paint, go with a 3-to-1 mixture of water to bleach.

Get started

Begin by using your pressure washer to spray down the entire exterior of the house. Make sure that you get into all cracks and crevices where dirt collects to get at all grime that might affect paint adhesion.


Once you’ve washed down the entire house, it’s time to rinse. Use pure water to get rid of any remaining bleach solution before allowing your home to dry completely. Be sure to save some water for this process, as you’ll need about one small bucket for every five minutes of pressure washing.


If using latex paint, use an oil-based primer to block out stains on the wood or brick surface. This will allow the paint to adhere once you’ve finished painting properly. If using oil or alkyd paint, skip this step and move on to painting immediately.

The Benefits of Pressure Washing Your House before Painting

The benefits of pressure washing your house before painting are many. First, it will make the paint adhere to the surface better. The second benefit is that it will remove dirt and grime that accumulates on the exterior of the building. This will make your home look better and require less maintenance in the future. Finally, it is more cost-effective than buying paint and hiring an outside contractor to prepare your home for new paint.

How to Prepare Your Home for Painting

Preparing your home for painting can be time-consuming and expensive. Pressure washing is one of the most cost-effective ways to prevent that. In addition, you want to wash away any dirt or grime that might be on the surface before you start painting because it’s just going to get in the way when applied later.  It’s also very important to remove all mildew because it creates a thick paste mixed with water and paint.


Now that your house is ready for new paint, it’s time to choose your color! But before making any big decisions, make sure that professional painters Perth trust are finished with the work!
