It is highly concentrated and powerful penetrating agents materials which is effectively react with cement to loosen the bonding strength . Best results can obtain on dry surface of cement.  RXSOL'S R & D  has developed this molecular cement dissolver as an alternative to using hazardous acids for concrete removal. Back-Set is a one-of-a-kind formula. 

RXSOL-22-2202-035 turned this vulnerability into an opportunity. "Back-Set" safely removes hardened concrete from a variety of difficult to clean surfaces. It break down the ionic bond in portland cement, releasing the cement from any surface to which it has adhered.

This liquid mixture specifically designed to deal with hard cases of cement cargo deposits or dry cement stains. Its proven advantage is the provision of immediate penetration and complete dissolution of cement, the result being a thorough cleaning.

Chemically Back-Set converts the positive ions in the hardened matrix into negative ions, which dissolves the cement into mud that can be rinsed away. Because it works chemically, rather than mechanically, Back-Set may be used to remove cured concrete, mortar, grout, and stucco from virtually any surface without harm.
