Will Washing My House Damage My Paint?

Keeping your home’s exterior clean is essential not only for aesthetic reasons but also for maintaining the longevity of the paint. We often get asked the question, “Will washing my house damage my paint?” This is definitely a valid concern, especially when considering the different methods one might use to clean a house’s exterior. In this blog post, we’ll cover the differences between soft washing, pressure washing, and pre-paint washing and explain why paint manufacturers recommend washing painted exteriors at least once a year.

The Importance of Washing Your House's Painted Exterior

Paint manufacturers, such as Resene, suggest that washing painted exteriors at least once a year can significantly extend the lifespan of the paint. Regular cleaning helps remove dirt, mould, mildew, and other contaminants that can erode and degrade the finish over time. Preventive maintenance—exterior washing—will keep your home looking fresh for longer and reduce the need for frequent repainting.

Soft Washing

What Is Soft Washing?

Soft washing is a cleaning method that uses low-pressure water combined with specialised cleaning solutions to deliver a gentle but effective clean. The House & Building Wash Company uses a combination of three different cleaning agents (a salt-based product, a grease-cutting solution, and a neutral detergent) to effectively break down dirt, mould, mildew, algae, and grime without the risk of damaging either the paint or the surface beneath.

Benefits of Soft Washing

Soft washing is effective for most surfaces but is especially ideal for delicate exterior surfaces such as painted walls, vinyl siding, and cladding. It provides a thorough and effective clean without the risk of peeling or chipping the paint.

The spray from a soft wash is so gentle that you can even run your hand under it!

Pressure Washing

What is Pressure Washing?

While pressure washing is a highly effective cleaning method, it can be too harsh for some surfaces, including painted surfaces. The high pressure can strip paint, cause chipping, and even damage the surface beneath the paint. Therefore, it’s crucial to use pressure washing selectively and professionally on appropriate surfaces such as concrete and raw timber.

Pre-Paint Washing

What is Pre-Paint Washing?

Pre-paint washing is a preparatory cleaning process that ensures the surface is clean and ready for a new coat of paint. This method involves a thorough cleaning to remove any dirt or other contaminants that could affect paint adhesion.

At The House & Building Wash Company, our pre-paint cleaning process is similar to our standard exterior soft washing process, with the main difference being the use of higher-pressure water to remove as much of the old paint as possible. A pre-paint wash could be considered something of a hybrid of the two techniques for the niche purpose of preparing the surface for painting.

Benefits of Pre-Paint Washing

• Enhanced Paint Adhesion: A clean surface ensures that the new paint adheres properly and lasts longer.

• Smooth Finish: Removing dirt and debris prevents imperfections in the paint finish.

• Long-Term Durability: Proper surface preparation, much like annual cleaning, can extend the life of the new paint job.

Conclusion: Cleaning Your Home and Protecting Your Paint

In conclusion, washing your home’s exterior is essential for maintaining the lifespan and appearance of the paint. Soft washing is the preferred method for painted surfaces due to its gentle yet effective cleaning power. Pressure washing should be used with caution and primarily on hard surfaces. Pre-paint washing ensures that surfaces are adequately prepared for a new coat of paint, contributing to a long-lasting finish.
