Aug 8


If you're like most homeowners, you'll want to paint the outside of your house at some point. Painting the exterior of your home can give it a new look and increase its value. However, the surface must be clean and free of debris for the paint to adhere properly to the wall. This blog post will go over how to clean exterior walls before painting to ensure that your project goes as smoothly as possible!

Various Methods for Cleaning Your Exterior Walls

Power Washer

If you plan to paint the exterior of your home, you must first clean the walls. A power washer, also known as a pressure washer, is an excellent tool for accomplishing this task quickly and efficiently.

When using a power washer on your exterior walls, keep the following things in mind:

  • First, adjust the pressure setting to suit the type of surface you're cleaning. When pressure washing, using too much force can damage brick and other delicate materials.
  • Second, always work your way up the wall from the bottom. This will keep streaks from forming as you move your pressure washer across the surface.
  • Finally, after using the power washer, thoroughly rinse the area. This will remove any residual dirt or debris that may cause issues when painting.

Scrubbing

Scrubbing is the process of cleaning exterior walls in order to remove dirt, mildew, and loose paint. Scrubbing is required to prepare the surface for painting and to ensure proper paint adhesion.

Scrubbing is classified into two types: wet scrubbing and dry scrubbing. Wet scrubbing is done with a water-soaked brush. This method of scrubbing removes more dirt, mildew, and loose paint. Dry scrubbing is accomplish with a brush that has not been soaked in water. Dry scrubbing removes less dirt, mildew, and loose paint but is less likely to damage the wall's surface.

The type of scrubbing you should use is determined by the condition of the surface being cleaned. Wet scrubbing is the best option if the surface is extremely dirty or if there is a lot of mildew. Dry scrubbing is the best option if the surface is only slightly dirty or if there is only a small amount of mildew.

Chemical Degreasers

Chemical cleaners are the most commonly used method of cleaning exterior walls before painting. They are simple to use and are available at any hardware store. TSP (trisodium phosphate) and Muriatic Acid are the two most common types of Chemical Cleaners.

TSP is an effective cleaner for removing dirt, grime, and stains from exterior walls. When working with TSP, it is critical to wear gloves and a mask because it can be harmful to your skin and lungs.

Muriatic acid is a less popular option for exterior wall cleaning, but it is still effective. When using Muriatic Acid, you must exercise extreme caution because it can eat away at your skin and clothing.

Summary

When preparing to paint the exterior of your home, it is always best to start by cleaning the walls. This will ensure that your new coat of paint applies smoothly and looks great for many years.
