Abstract: A paint guard for protecting frame windows or doors, includes a rectangular framework of four right annular frame members which are telescopically interconnected so as to permit the framework to expand and contract in height and width. Flanges at the periphery of the framework are provided for clamping the framework to the window frame upon contractin of the framework around the window frame. A biasing spring mechanism is provided for urging the framework to its contracted position. The central region of the framework is open. A flexible covering contained in rollers is utilized to cover the opening. Locks are provided to selectively lock certain frame members together for certain applications. A method of protecting a framed window or door during painting is also disclosed.
