Roller marks: A stipple texture pattern from the roller, not desirable or planned.
Roller marks probable causes: Incorrect rolling technique. Frequently, the use of an incorrect roller cover with an excessive nap length. Over loading the roller cover with paint. Failure to spread the paint uniformly. Painting over a slick surface without proper priming.
Roller marks solutions: Use a quality recommended roller cover with the correct nap length. Make certain the roller is rolling, not sliding. Begin with an upward zigzag stroke in an “M” or “W” pattern and fill in the pattern with parallel strokes without leaving the surface.
Primers & interior finishes: Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality interior paint in the color and sheen of your choice.
