To rake out and renew 2,600 linear metres of sunken & failing terrazzo joints. Failed grout was cut out and replaced, then polished with coarse, medium and fine abrasive discs, on machines fitted with dust control. The aisles were then diamond polished with battery operated cleaning machines fitted with a variety of diamond pads. The entire area was sealed & buffed on completion.
Straw coloured grout
Joints were cut to approximately 10mm depth using diamond-tipped blades. Vertical edges were cleaned by the cutting and improved the bonding for the new grout. Dust-control was utilised to ensure that dust was at a minimum during the cutting and grinding processes.
A combination of hand and machine grinding was employed to remove excess grout, leaving a flat finish ready for polishing. Where joints had sunk these were topped up prior to the final polish.
Two powerful ride-on machines enabled us to complete the diamond polishing in a very fast time, thus reducing client down-time.
