What is the outcome of not properly preparing a surface before painting?

Not properly preparing a surface before painting can lead to potential paint adhesion failures. Surface preparation is critical in ensuring that the paint bonds correctly to the substrate. This involves cleaning, sanding, and possibly priming the surface to create a suitable texture and remove contaminants that could prevent effective adhesion.

When a surface is not adequately prepared, factors like dirt, old paint residues, or an uneven texture can interfere with the paint's ability to adhere properly. As a result, the paint may flake, peel, or bubble shortly after application, leading to a compromised finish that requires costly repairs or complete repaints. Proper preparation is essential to achieving a durable and long-lasting paint job, ensuring that the paint performs as intended throughout its lifespan.
