Before painting over an existing surface, it’s important to know what type of paint is already there.
In this episode of Behind the Brush, Don Polson demonstrates a simple test homeowners can use to determine whether their walls are coated with latex or oil-based paint.
Why does this matter?
Different paints require different preparation methods, and applying the wrong product over an incompatible surface can lead to peeling, cracking, or poor adhesion.
You’ll learn:
- The simple rubbing alcohol test
• How latex paint reacts differently than oil paint
• Why surface compatibility matters
• How professional painters evaluate surfaces before painting
Understanding the surface you’re painting is one of the most important steps in achieving a long-lasting finish.
