Roller spattering is the tendency of a roller to throw off small droplets of paint during application.
Generally it’s caused by incorrect roller technique and applying the paint too rapidly. Using low quality paint and/or roller as well as incorrect roller covers can also cause spattering.
Always choose a high quality paint. They are formulated to minimize spattering. The right paint should be paired with the right roller too – choose a high quality roller, with the appropriate nap length. When painting, be careful not to overload the roller with paint as this will result in excess spatter. Working in three-feet square sections, apply the paint in a zigzag 'M' or 'W' pattern, and then fill in the pattern – this will also reduce the likelihood of spattering, giving you smooth, consistent paintwork.
