A lock assembly for a roller assembly is provided. The roller assembly comprises a frame comprising a support portion; and a roller rotatably mounted on the support portion of the frame. The lock assembly comprises: a lock member support; a lock member moveable relative to the lock member support between a first position and a second position; wherein when the lock assembly is employed with the roller assembly, with the locking member in the first position the roller is rotatable relative to the frame and with the locking member in the second position, the locking member engages with the roller to prevent rotation of the roller relative to the frame. A roller assembly comprising the lock assembly is also provided.

A paint roller locking mechanism that prevents a roller cover from rotating is designed to apply paint in a smoother manner that typically provided by a roller. The locking mechanism prevents the roller cover from rotating as it is rolled along the surface being painted. This, in effect, allows the roller cover to emulate a paint brush, allowing for a smooth painted surface without surface irregularities. The locking mechanism may easily pivot away allowing the paint roller to function in a normal rolling manner, as well as allow a user to reload the roller or apply bulk paint when needed.
