Video transcript

The best primer for plaster walls is a high-quality acrylic latex primer. This type of primer provides excellent adhesion, seals the porous surface of plaster, and offers a smooth base for paint. Additionally, it resists moisture, which helps prevent peeling and flaking. For stained or heavily repaired plaster walls, consider an oil-based or shellac primer for extra durability and stain-blocking capabilities.
