Definition: Failure of paint to dry to a smooth film, resulting in unsightly brush and roller marks after the paint dries.
CAUSES:
* Use of low-quality paint
* Use of low-quality tools/wrong roller cover
* Re-brushing or re-rolling areas that are partially dried
* Too much heat – usually above 90 ºF – or too little humidity, which causes rapid drying of the paint, preventing the film from flowing out properly
* Use of paint not specifically made with good flow and leveling properties
PAINTING POOR FLOW AND LEVELING SOLUTIONS:
* When using a roller, be sure to use a cover with the correct nap length for the type of paint being used. Use of a high-quality brush is important – a poor brush can result in brush marks and uneven appearance.
* Avoid painting under conditions that cause rapid drying of the paint to avoid painting poor flow and leveling.
* Use a high-quality paint formulated with ingredients that enhance painting poor flow and leveling.
