Abstract: A paint tray with disposable liner system generally comprises two components, a paint tray base, and a liner holding frame which cooperatively engages with the paint tray base to securely hold a paint tray liner therebetween so as to position the paint tray liner overtop of the interior surface of the paint tray base. The paint tray base has a bumper extending around the periphery of the paint tray base from the exterior surface of its walls. The liner holding frame is sized to slidingly fit onto the paint tray base and engage the bumper, wherein engagement of the liner holding frame with the bumper securely fixes a paint tray liner in place therebetween. A cover can optionally be included in the system that includes a cover holding frame sized to fit on top of the paint tray base above the liner holding frame, wherein the cover holding frame comprises a channel to receive a top end of a corresponding wall of the paint tray base to securely fix the paint tray cover in place therebetween.
