A tool used for covering or shielding a length of baseboard, trim or molding that is connected to a wall being painted. The adjustable protective paint shield has a fixed length center section from which are adapted two telescopic inner sections that extend to a desired length in order to cover or shield varying lengths of baseboard or trim. Each section has a general appearance of an elongated inverted L-shape. The center section has a plurality of pivotally affixed legs used in securing the shield in an upright position. The legs have an outwardly arched shape. The ached shape allows the bottom of the leg to sit securely flat against a floor while supporting the adjustable paint protection shield upright and tightly against a section of baseboard or trim being covered.
