Glass beads are thrown into the still fresh and wet (!) coating and dry in together. A good 1/3 of the beads can peek out of the surface.
Slip resistance is possible - with optimal application - up to slip class R11.
For private use, 100g to 150g per square metre is sufficient. To ensure good slip resistance, the following is recommended:
Class R9: 500g per square metre
Class R10: 1,000g per square metre
Class R11: 3,000g per square metre
! Remember to observe local regulations and standards to meet the required safety standards.
