Buff Bronze/Nylon Combi provides the ideal bristle combination if only one brush is used. For best results use the bronze side to open base structure before waxing and after scraping wax from the base, then use the nylon side to buff and polish the base. German-made Tools4Boards brushes are the finest quality available made using only beech wood, premium bristle materials and feature a natural beeswax finish (instead of paint) to reduce impact on the environment. Brushes should be used with overlapping strokes in one direction (shovel to tail) to open the base structure, assist in cleaning the base, prepare the base for optimal wax absorption and to buff and polish the base.
