Nappy Sack Frame

Making concrete or Mortar washout much easier, the Nappy Sack Frame is designed to accommodate revolutionary BlueRinse Nappy Sack, a self-dosing bag which separates the solids, automatically reducing the pH of the water. Engineered with an oil adsorbent liner, the fabric is impregnated with pH Blue, which is released into the water as it passes through the wall. The collected water will typically have a pH below 9.
