Abstract
A manual painting device (brush/roller) allows surfaces to be coated continuously without the brush or roller having to be dipped manually in order to be loaded with paint. The kit can be mounted on a trolley/structure for transport or can be used in a backpack with a tank connected to a pump and from which the paint flows automatically, conveyed through a hose to the applicator element (brush/roller), such that the applicator element is loaded automatically from inside the painting accessory itself.
