Claims12
A method for applying a polyurethane composition, as a flooring material,
- wherein the polyurethane composition comprises:
- A) a polyol component (A) comprising at least one polyol;
- and
- B) a hardener component (B) comprising at least one polyisocyanate,
- wherein the polyurethane composition further comprises 0.5-8 wt. % of hollow glass microspheres, based on a total weight of the polyurethane composition,
- wherein the method comprises:
- a) providing a space where the polyurethane composition is to be applied;
- b) mixing components (A) and (B) of the polyurethane composition to obtain a mixed polyurethane composition;
- c) applying the mixed polyurethane composition on a desired location and in a desired shape within the space provided;
- d) allowing the applied mixed polyurethane composition to cure;
- and
- e) mechanically treating a surface of the cured polyurethane composition, by grinding the surface of the cured polyurethane composition to remove a thickness of the cured polyurethane composition from the surface, 5-50%, of the thickness of the cured polyurethane composition.
