Paint work can appearing ‘bitty’, with an uneven or rough finish to the surface.
Dusty atmosphere, unclean substrate, incorrect preparation and unclean application tool can all play a part in leaving a 'bitty' finish on paint work.
To remedy a ‘bitty’ finish you must rub the surface down using a suitable abrasive tool or paper and re-coat. Always ensure that the substrate area is clean and prepared, and application tools have also been cleaned thoroughly before application.
You can also strain the paint to ensure that any particles that may sit within the product have been removed.
