Abstract: Device for the application of fluid coats to surfaces. The device includes a main body (1) through whose back part closed (1b) and by means of a movable connection (2a) with a brake (20), connects to a command grip (2) that allows several angular positions for the main body (1). It has a set of rollers (3) that, rotationally mounted on the lateral walls (1c) of said main body (1) and bulging out by the open front part (1 a) of same (1), are fed with the fluid supplied by a distribution device (5) that is connected to a feeding circuit (4) and whose supply comes from an auxiliary feeding device (40) that may be regulated by an operation means (4b).
