Abstract
A flooring system for floors exhibiting surface movement, and/or for cushioning hard floors, which includes an epoxy or polyurethane primer, a two-component ambient temperature cured polyurethane membrane substrate base atop the primer of a urethane grade castor oil, polyether based polyol, a tin catalyst and a thickening agent, along with a polymeric isocyanate activator, and a polyurethane or polyurea, aromatic or aliphatic coating atop the substrate base, in providing a very tough, but flexibly soft non-cracking overlay which moves with the floor.
Claims18
A flexible flooring system for floors exhibiting surface movement comprising:
- an epoxy or urethane primer;
- a two-component ambient temperature cured polyurethane membrane substrate base atop said primer of a urethane grade castor oil, polyether based polyol, a tin catalyst and a thickening agent, along with a polymeric isocyanate activator;
- and a polyurethane or polyurea, aromatic or aliphatic coating atop said substrate.
A method of cushioning hard flooring surfaces comprising the steps of:
- first, sealing said surface with an epoxy or polyurethane primer;
- second, applying a two-component ambient temperature cure polyurethane membrane substrate base atop said primer of a urethane grade castor oil, polyether based polyol, a tin catalyst and a thickening agent, along with a polymeric isocyanate activator;
- and third, applying a polyurethane or polyurea, aromatic or aliphatic coating atop said substrate base.
