What are Roller Marks?

Much of the problem with using rollers, and the reason why some avoid using them when they can, is due to roller marks, or stipple, which are the roller patterns unintentionally left on the painted surface post-painting. This can occur when using low-quality, cheaper rollers, or in effect using an incorrect rolling technique. As it is, the major issues can occur if rollers are not used in the right way when applying the paint to a fresh surface. As the proper technique when using rollers follows certain steps, these are listed as below. The higher quality rollers tend to roll paint from the pallet to the paint surface more evenly due to the uniformity of the roller itself. Furthermore, rollers should be dampened prior to paint use, and an even roll from corner to end should be done using a zig-zag pattern resembling an ‘M’ or ‘W’, using parallel, even strokes without breaks.

Following the steps above reduces paint spatter, mud cracking, and stipple on paint surfaces. During the paint application process, this technique should be utilised at all times. Pre-dampening the rollers, employing an ‘M’ or ‘W’ zig-zag technique without lifting or uneven strokes, and using quality paint is essential to avoiding roller marks during the post-paint process.
