You will not need a mask for most low risk painting jobs involving a brush or roller to apply low VOC paints / coatings. If you are spraying these you may need to wear eye protection and the right mask. In general you should ask your supplier for:
a half-face or a full-face mask respirator with replaceable A2P3 filters for short spray painting tasks up to an hour and within a poorly ventilated area a powered (fan-assisted) respirator with a visor and replaceable TH marked A2P3 filters for longer paint spraying tasks It is also important that these masks fit properly.
