This occurs when a roller throws off small droplets of paint during application.
- Using an exterior paint on an interior surface.
- Using lower grades of water-based paints.
Use a higher-quality paint, as these are specifically formulated to minimise spattering, and apply it using a high-quality roller offering proper resiliency. In some cases, a quality wall paint may be used for ceiling work to ensure maximum spatter resistance.
Try not to overload the roller with paint, as this will result in excess spatter, as will overworking the paint once it is applied to the surface. Work in sections, applying the paint in a zigzag ‘M’ or ‘W’ pattern, and fill in the spaces using even, parallel strokes.
