The Tile Grout Sponge Machine is a continuous band sponging machine for sponging off cement grouts. The machines use a continuous sponge band that is fed through a water bucket and rollers; the excess sludge and water is squeezed out leaving the sponge clean to repeat the cycle. It quickly cleans off grout from quarry tiles & pool surround, granite sets & pavers and leaves uniform & strong joints, saving up to 70% of grouting time & labour.
