Painted metal panels are subject to the same types of failures as metal grid is. Porous types of panels can emit odors, absorb stains, and support mold and mildew if exposed to moisture. In addition, panels with textures, fissures, perforations, or crevices have more surface area that can harbor contaminants. Their surface may be discolored or soiled by many of the same processes affecting the appearance of grid. Grid covers are available in white and colors that match or are compatible with popular panel colors and faux finishes.Ĭeiling panels comprise the majority of a ceiling’s surface and present most of its aesthetic failures. Slide-on covers require less labor they can be applied without removing adjacent panels and are easy to install without special training or tools. Adhesive types require grid to be thoroughly cleaned, and they must be pressed firmly into place to assure adhesion. Available options include adhered strips and plastic covers that slide over the bottom flanges of standard T-bars and perimeter angles. Grid covers may be a more cost-effective choice when labor is included in the calculation. Adjacent ceiling panels, especially fragile or porous panels would have to be masked or removed. Some paint manufacturers recommend sanding existing gloss and semi-gloss coatings before repainting. Any rust must be removed and priming may be required. Before repainting, the grid must be cleaned thoroughly to remove contaminants. Grids can be refinished either by painting or by covering with a refinishing strip. Panels with textures and tegular edges provide additional surface area to trap contaminants and make cleaning more challenging.įor grids that cannot be cleaned adequately, refinishing may be an option.

It may be necessary to remove or mask such panels to protect them-both are labor-intensive processes that can also dislodge fibers and dust. Some types of ceiling panels can be damaged by liquid cleaning products and even gentle brushing or vacuuming can cause erosion of fibers. If ceiling panels are in-situ then, consideration must also be given to how the proposed cleaning technique will affect panels. Common household or janitorial cleaning products will usually do the job always test in an inconspicuous location on grid before applying any cleanser broadly. Soiling that is stuck to the surface requires washing. Lightly attached dust or dirt may be wiped or vacuumed off. Prior to cleaning the grid, adjacent ceiling panels, wall finishes, and anything beneath the ceiling may have to be protected, depending on the messiness of the cleaning procedure and how damage-resistant the adjacent materials are. In many cases, simple cleaning may be all that is required. The appearance will be particularly jarring if dirty grid is juxtaposed against new panels. Grid that no longer matches the color adjacent ceiling panels can draw attention to the deteriorated appearance of a ceiling. Grid may also get stained or discolored by indoor air contamination, ordinary dust and grime, sprayed particles, splashed liquids, airborne grease, smoke, and handling with dirty hands. Steel T-bar can rust, despite a thin galvanized coating, especially if it has been scratched through to the underlying steel or is located in a humid or chemically aggressive environment. Painted coatings are prone to fade or yellow. The grid’s appearance can be less enduring. However, the non-woven acoustic fabric behind the perforations may have to be replaced since grime attached to the fabric is more difficult to remove and may also interfere with noise reduction. These painted metal ceiling panels can be rejuvenated by wiping with a degreasing cleaning agent.
