HOW TO AVOID GHOSTING ISSUES WHEN USING WHITEBOARD PAINT

Ghosting is the process by which the surface of a traditional whiteboard or a whiteboard painted wall fails to erase completely, leaving behind gray cloudy-looking stains and stray dry erase ink markings that can make the surface unsightly and hard to read from. Factors that can eliminate ghosting on a whiteboard coated surface include (1) application of a compatible base coat; (2) use of a proper type of paint roller sleeve; (3) application in one even coat;(4) use of low-odor dry erase markers for writing and a microfiber cloth for cleaning; and (5) avoidance of back rolling or re-rolling of the whiteboard coating.
