Special features RUBI has a wide range of rubber floats for grouting ceramic tiles, with ergonomic wooden handles. PRO grout floats by RUBI are available in different rubber hardnesses for the best result based on the grout joint width. One of the PRO grout float models features a white abrasion-resistant rubber and offers flexibility, ideal for filling joints up to 3 mm wide. This flexibility ensures homogeneous joint filling and perfect compaction of the grouting material. The other PRO grout float models have an extended rubber of medium hardness and are adaptable to any joint width. PRO grout floats are particularly distinguished by their lightness. This aspect is very beneficial and highly appreciated by professional tile setters when they have to grout large areas. Technical data Black foam rubber
