The #800 Multi-Flex Dance Sprung Sub-Floor installs quickly and easily. Boards are 5 7/16’’ wide tongue and groove, 1 1/8’’ thick, 7 ft long and weigh 3 lbs per sq. ft. Boards are made out of a composite of Birch plywood. Simply glue (also included) the boards to each other, there is no nailing, and the Sprung Sub-floor is finished.

Special Note: When installing the The #800 MultiFlex Dance Sprung Sub-Floor, the tongue and grove boards fit together very snug. Just a small amount of glue between the board is required. Remember more is not better. If too much glue is applied, you will float the joint and glue will come out the seams. If any glue comes out onto the finished surface remove immediately, do not allow to dry on the finished surface.

When the boards are glued together they form a smooth, undetectable joint making a totally smooth, flat surface ready for you to roll out your Marley vinyl dance floor surface. Because the boards are glued instead of nailed or screwed, you won’t feel any nails or screw heads or holes through the Marley vinyl dance floor surface.

Please refer to the installation guide for information on moisture content, going over concrete and placement of the first boards with expansion gap.

After installation of the #800 Multi-Flex Dance Sprung Sub-Floor is complete you are ready to apply the Marley vinyl dance floor covering of your choice. Marley vinyl dance floor surfaces can be temporary. A temporary installation means the vinyl surface flooring is rolled out onto the #800 Multi-Flex Dance Sprung Sub-Flooring. All seams and edges of the vinyl surface flooring would then be top-taped with a vinyl dance floor tape.

Another type of temporary installation for the vinyl dance floor surface, would to use double faced adhesive vinyl dance floor tape. This type of tape would go on the wrong side of the vinyl surface and then stick directly to the #800 Multi-Flex Dance Sprung Sub-Floor.

Permanent installation of Marley vinyl dance floor surface can also be done on top of the #800 Multi-Flex Dance Sprung Sub-Floor. Flooring companies can glue down the Marley vinyl dance surface and heat weld the seams. One important piece of information: if the vinyl surface is going to be glued down and then heat welded, the glue and heat welding rod will need to be purchased from the company that will be providing the Marley surface vinyl.

Before you start to roll out any vinyl performance surface, make sure the #800 Multi-Flex Dance Sprung Sub-Floor after installation is clean. Do not allow any scattered pieces of waste such as dust, dirt or sheet rock sanding to be left on the floor. If any type of debris is left on the sub-floor and not cleaned up, it will telegraph through the vinyl dance surface and make it look lumpy or bumpy and could cause a hazardous surface performers could trip on.
