20210180266 · 2021-06-17 ·

Disclosed herein is a method of resurfacing a sports court. This method involves applying a first adhesive to an existing sports court; curing the first adhesive to a tacky state; applying a thin fabric onto the first adhesive, wherein the thin fabric has a first side applied to the first adhesive and a second side opposite the first side and wherein the thin fabric is capable of releasing from the tacky state of the first adhesive; applying a second adhesive to the second side of the fabric; applying an elastic mat on top of the second adhesive, wherein the elastic mat has a first side applied to the second adhesive and a second side opposite the first side; and applying a sealer to the second side of the elastic mat.

Method, apparatus and system for producing a polyurethane sports flooring

A method for producing polyurethane flooring includes providing polyurethane reactive components including a isocyanate component and a polyol component, determining environmental data, determining process parameters for mixing the polyurethane reactive components, wherein the process parameters depend on the environmental data, mixing the foam for the polyurethane flooring by mixing the isocyanate component and the polyol component using a froth foam process with the process parameters, applying a first lane of the liquid foam to a ground, applying a second lane of the liquid foam to the ground, wherein a side edge of the second lane gets in contact with a side edge of the first lane, wherein the process parameter are determined so that the foam of the first lane is not cured before applying the foam of the second lane. Furthermore, the invention relates to an apparatus and a system for producing a polyurethane flooring.
