You can use it to paint entire walls, fix up damaged or dull areas, and paint or repaint furniture.This device has super-absorbent fibers that will lock the paint into the rollers so it won’t come off until the rollers have touched a surface.Therefore, you won’t experience the same dripping and spattering that you likely would with other paint rollers.That means you won’t need to tape up areas that you don’t want covered in paint, and you won’t have to switch to a smaller brush to complete certain areas.
