The invention relates to a method for manufacturing a phosphor screen on an inner surface of a CRT panel, having a faceplate, a blend radius, and a sidewall. The method includes the steps of depositing at least one phosphor layer (R, G, B), containing a binder, on the inner surface of the faceplate, and then coating the phosphor layer, the blend radius, and at least a portion of the sidewall with a filming material. The coating of the filming material is dried to form a film. The film, or at least that portion thereof overlying the blend radius and the side wall, is contacted with an adhesion-promoting, blister-reducing solution which contains operable quantities of silica particles, a low vapor pressure alcohol and deionized water. A metal layer is deposited on the film, and the film and the binder contained in the phosphor layer are volatilized.
