Undiluted : In cases where we deal with heavy deposit build–up, CEMENT REMOVER must be applied undiluted.
Diluted : In cases of light deposition, on large surface areas, a solution between 10–40% may be used.

METHOD ::: 
1.For heavy deposition and thick layers  of cement, a concentrated and  stronger cleaner will be necessary to cut through the layers of cement.
2.Use a scraper, metal scrubber or flat head screwdriver to remove as much of the cement as possible.
3.For the remaining cement, apply this chemical 
4.Once the cement loosens, scrub the area with a scrubber until it is all removed from the surface.
5.Rinse the area well with clean water.
6.Clean the area with alkaline soap and water 
7.Flush system completely.

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. It uses an active ingredient found in sugar cane syrup, and is completely biodegradable.

RXSOL-22-2202-025 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.

Citric Acid is a water treatment chemical used as pH control and for the removal of iron and other elements from fouled water softeners. Removes hard water built up, scale and lime. Citric Acid 50% Solution is used as a preservative, acidifier, chelator, and flavoring in various sections of the food and beverage industry.
