Guide to Cleaning & Degreasing for Paint-Ready Surfaces

Preparing a surface for painting is a critical step in any painting project. A clean and well-prepared surface ensures a long-lasting and professional-looking finish.

Understanding the Importance of Surface Cleaning and Degreasing

Before diving into the cleaning process, it is essential to understand the importance of surface cleaning and degreasing. A dirty or greasy surface can severely affect the adhesion and durability of paint, leading to peeling, chipping, and unevenness.

According to the US General Services Administration, proper surface preparation is crucial in ensuring long-lasting paint performance.

Thorough cleaning and degreasing play a vital role in reducing the possibility of paint failures and ensuring a smoother, more attractive final result.

Identifying Contaminants on the Surface

There are various contaminants that can be found on surfaces, including dirt, grease, oil, and mildew. These contaminants can affect paint adhesion, leading to improper coverage and shortening the lifespan of the paint job.

To properly clean and degrease a surface, it is essential first to identify the type of contaminants present.
