What To Use To Clean A Painted External Surface Before Painting?

Homeowners should regularly inspect exterior paint jobs for signs of damage, as climate can affect the longevity of paint jobs. To ensure better paint adhesion and a smoother finish, homeowners should remove dirt, grime, and mildew from their home’s exterior walls. Cleaning exterior walls can be achieved through various methods, such as using a warm water and sponge with added detergent, using a bleach solution for mildew, using TSP or chemical cleaner, or using a power washer for exterior siding/walls only.

For metal surfaces, remove any rust by wire brushing or sanding the surface and use Dulux All Metal Primer before painting. Power washing is one way to clean exterior walls before beginning the project. Soft wash and power wash are both effective at getting the exterior of your house clean and ready for paint. Chemical cleaners are the most popular way of cleaning exterior walls for painting, and they are easy to use and can be found at any hardware store.

For mildew, use bleach or mildew-cide, and add TSP if there is extra grime that needs to be cleaned off. Pressure washing before painting your house is beneficial as it simultaneously cleans the exterior surface and extends the life of the paint brushed over it. Clean wood before painting with a mild detergent solution or wood cleaner to remove dirt, grease, and old paint. Rinse thoroughly and let dry.

In summary, cleaning exterior walls before painting is crucial for ensuring better paint adhesion and a smoother finish. By using mildew-cide, power washing, and cleaning wood, homeowners can ensure a clean and long-lasting paint job.
