If you’re like most homeowners, you’ll probably want to paint your exterior walls at some point. Painting your home’s exterior can give it a fresh new look and increase its value. However, for the paint to adhere properly to the wall, the surface must be clean and free of debris. In this blog post, we will discuss how to clean exterior walls before painting so that your project goes as smoothly as possible!
Different Ways to Clean Your Exterior Walls
If you’re painting the exterior of your house, you’ll need to clean the walls first. A power washer, otherwise known as a pressure washer, is a great way to do this quickly and efficiently.
There are a few things to keep in mind when using a power washer on your exterior walls:
- First, be sure to adjust the pressure setting according to the type of surface you’re cleaning. Too much force when pressure washing can damage brick and other delicate materials.
- Second, always start at the bottom of the wall and work your way up. This will prevent streaks from forming as you move across the surface when pressure washing.
- Finally, be sure to rinse the area well after washing it with the power washer. This will remove any residual dirt or debris that could cause problems when you paint.
Scrubbing is the process of cleaning exterior walls to remove dirt, mildew, and loose paint from the surface of the wall. Scrubbing is necessary to prepare the surface for painting and to ensure that the paint will adhere properly.
There are two main types of scrubbing: wet scrubbing and dry scrubbing. Wet scrubbing is done with a brush that is soaked in water. This type of scrubbing is more effective at removing dirt, mildew, and loose paint. Dry scrubbing is done with a brush that is not soaked in water. Dry scrubbing is less effective at removing dirt, mildew, and loose paint but is less likely to damage the surface of the wall.
Which type of scrubbing you should use depends on the condition of the surface you are cleaning. If the surface is very dirty or if there is a lot of mildew, wet scrubbing is the best option. If the surface is only slightly dirty or if there is only a small amount of mildew, dry scrubbing is the best option.
Chemical Cleaners are the most popular way of cleaning exterior walls for painting. They are easy to use and can be found at any hardware store. The two most common types of Chemical Cleaners are TSP (trisodium phosphate) and Muriatic Acid.
- TSP is a strong cleaner that will remove any dirt, grime, or stains from your exterior walls. It is important to wear gloves and a mask when using TSP, as it can be harmful to your skin and lungs.
- Muriatic Acid is a less popular choice for cleaning exterior walls, but it is still effective. It is important to be very careful when using Muriatic Acid, as it can eat away at your skin and clothing.
If you’re getting ready to paint the exterior of your home, it’s always best to clean the walls first. This will ensure that your new coat of paint goes on smoothly and looks great for years to come.
