Ultra Grouting System will cut your grouting time by 30-50% and you will never squeeze a sponge again. When grouting, just dip the sponge into the bucket and roll the sponge over the rollers, then start rubbing in a flat circular motion. The slits in the sponge trap more grouting materials than a conventional sponge and the grating in the larger bucket allows it to rinse clean. This process will tool the joints. To clean the tile, dip and roll the sponge clean and drag the sponge flat but diagonally this time, across the tile and you are finished! You will be amazed how clean the floor will be and you have eliminated the need to dust as well. You will find this system faster and better than the old way and once you've tried it, the only way!
