It is important that all debris be removed from the underlying surface before laying the Interlocking Snap Together Dance Floor system in place so there are no lumps and the floor lays flat on the surface. In cases of surface irregularities, fill or grind down the surface to bring it as level as possible. Interlocking Snap together Dance Floor may be cut or trimmed using conventional hand tools such as a table saw or jig saw with standard blades. Edges may be filled or sanded after cutting if needed. To ease installation, lay out patterns or designs of your floor on graph paper prior to installation.
