The Springflex unique "Quick Clip" Dance Floor Systems enable you to install this high-quality dance floor without removing the old floor surface. Springflex flooring can be installed over any dry solid level subfloor. This includes existing flooring such as concrete, chipboard, carpet, tile, sheet vinyl, ceramic or wood. Surface variation should not exceed 3/16" within a ten-foot radius. The transition height including the foam layer results in a floor system 1-1/4” or 1-5/8” in increased height. This floor provides excellent resilience and high shock absorbance.
