The fully exposed polyurethane flooring system is a solvent-based, thin polyurethane topcoat designed as a UV-resistant sealer for concrete and various Vetotop epoxy and polyurethane flooring and coating systems. Incorporating special additives and adhesion promoters, this system ensures excellent penetration and adhesion to minimally profiled concrete. UV stable for exterior applications, it cures rapidly and provides a sealed surface ideal for all-weather exposure. The finish coat delivers a hard, gloss surface with exceptional scratch resistance and easy cleanability
