Abstract
Methods, systems and polished overlays utilizing an uncoupling membrane between a substrate (e.g., floor) and a deposited polishable overlay. The overlay may be a self-leveling, polishable overlay. An uncoupling membrane is secured to a substrate followed by directly depositing a polishable overlay over and contacting the uncoupling membrane. The uncoupling membrane secures the polishable overlay to the substrate without use of a primer/broadcast sand layer. The polishable overlay may fill voids in the uncoupling membrane and may be deposited over the uncoupling membrane to a thickness residing above a top surface of the uncoupling membrane. The polishable overlay may be polished once cured whereby the uncoupling membrane reduces stresses in the overlay layer during polishing.
Claims20
A method of installing a polishable overlay comprising:
- providing a substrate;
- securing an uncoupling membrane to the substrate;
- depositing only a polishable overlay directly over and contacting the uncoupling membrane to secure the polishable overlay to the substrate, the polishable overlay filling any voids in the uncoupling membrane and being deposited over the uncoupling membrane to a thickness residing above a top surface of the uncoupling membrane;
- and
- polishing a top surface of the deposited polishable overlay to provide a polished overlay, wherein the uncoupling membrane reduces stresses applied to the polishable overlay during polishing.
A system of an overlay placement comprising:
- a substrate;
- an uncoupling membrane secured to the substrate;
- and
- a polishable overlay residing directly over and contacting the uncoupling membrane to secure the polishable overlay to the substrate without use of a primer/broadcast sand layer, the polishable overlay filling any voids in the uncoupling membrane and being deposited over the uncoupling membrane to a thickness residing above a top surface of the uncoupling membrane.
A polished overlay flooring comprising:
- an existing floor;
- an uncoupling membrane secured to the existing floor;
- a polishable overlay residing over and directly contacting the uncoupling membrane to secure the polishable overlay to the existing floor without use of a primer/broadcast sand layer, the polishable overlay filling any voids in the uncoupling membrane and being deposited over the uncoupling membrane to a thickness residing above a top surface of the uncoupling membrane.
