Dr. Schutz® PU Sealer is a water based 2 part polyurethane transparent sealer with outstanding durability and long term protection. It reduces dirt adhesion and the time needed for day-to-day maintenance. The hardwearing sealer film has an excellent elasticity and good resistance against chemicals. Easy and safe to apply with excellent adhesion. The manufacturing is located at Dr. Schutz GmbH, Holbeinstraße 17, 53157 Bonn, Germany. The raw materials are added together and mixed according to the recipe. For this purpose, a stirring device, pumps, stackers, etc. are required, powered by electricity and gas. The finished lacquer is drawn onto IBC's by free fall or pump and filled from the IBC’s into canisters by a filling machine. The crosslinker is produced according to the recipe at a third-party filler and filled by machine in bottles delivered to the manufacturing site on pallets.

Before application, the floor needs to be cleaned and roughened. First a wet cleaning using a detergent is carried out, followed by a neutralisation/post-cleaning with clear water. Final, roughening of the surface is necessary, to ensure a good adhesion of the sealing. The PU Sealer lacquer is mixed on site with the crosslinker in a ratio of 10:1. The mixture is then applied to the properly prepared surface, with a coverage of 50 ml/m² (80-100 ml/m² in case of wood, cork or decorative screed floors). The application of two layers is recommended, for highly absorbent surfaces the consumption can be higher.
