TEMPORARY GRATE COVER FOR PAINT SPRAY BOOTH AREAS ABSTRACT OF THE DISCLOSURE A cover fox paint spray area grates, including grates of the kind having perimeter blades bounding the perimeter of the grate, plural grate blades running in spaced parallel direction along one dimension of the grate and plural grate cross members extending transverse to the grate blades. The cover is arranged for shielding the grate blades and grate cross members from paint particles entrained in air drawn down through the grate and for facilitating installation of the cover on the grate without substantially inhibiting air flow down through the grate. The cover comprises a lightweight plastic one piece member having (1) a top wall comprising perimeter portions integral with plural length and width cross portions bounding a plurality of openings substantially coextensive with corresponding openings in the grate to be covered, and (2) skirts depending into the openings from the perimeter portions, length cross portions and width cross portions. Parts of the skirts adjacent said top wall are positioned close to the top of the grate blades and grate cross members. A pair of the skirts flank each grate blade and cross member. Each pair of flanking skirts is downwardly divergent so the space between the bottom edges of such pair of skirts is wider than the space between the top edges of the skirts. The skirts bounding each opening define a steep funnel shape such that the opening has a somewhat larger area at the top than at the bottom thereof. The skirts in each opening are connected at the corners thereof such that the skirts form a continuous perimeter wall for such opening.
