Barwalt Ultra Grouting System This complete grouting system will cut your grouting time by 30-50% and you will never squeeze a sponge again! The slits in the sponge trap more grouting materials than a conventional sponge and the grating in the bucket allows it to rinse clean. You will find this system faster and better than the old way and, once you've tried it, the only way. The Barwalt Ultra Grouting System Kit includes a large bucket, two ultra-comfortable cushioned grip handles with grout sponges, and an abrasive and non-abrasive scrub pad for the wall handle.
