Poor flow and levelling is when paint fails to dry to a smooth film, resulting in unsightly brush and roller marks after the paint dries.

Possible Cause
Causes of poor flow and leveling include:
- Using inferior quality paint
- Applying additional paint to 'touch up' partially dried painted areas
- Re-brushing or re-rolling partially dried painted areas
- Use of the wrong type of roller cover or a poor quality brush
Solution
Use a premium quality water-based paint. These are generally formulated with ingredients that enhance paint flow and lead to a smooth film. When using a roller be sure to use a cover with the recommended nap length for the type of paint being used. Use of a high quality brush is also important; cheaper brush can result in bad paint flow and levelling.
