GLC Concrete Dissolver works by attacking and dissolving the glue bond in Portland cement, It deconstructs the bond between the Portland and the other ingredients such as sand or gravel. It turns the material into a soft mush which does not require hazardous waste disposal. The amount of time required for this process is strictly proportional to the thickness of the concrete being dissolved.
GLC Concrete Dissolver normally works in 10 to 15 minutes depending on the application. The amount of soak time will really depend in the thickness of the material trying to be removed. The minimum should be about 10 minutes, but thicker materials may take 30 or more and repeated applications. It is important to keep the material covered with the concrete dissolver and not let it dry out.
GLC Concrete Dissolver is acidic the same way that vinegar is. There is no muriatic acid, sulphuric acid, phosphoric acid, citric acid in GLC Concrete Dissolver. The main raw material is derived from sugar cane. Making it, non-toxic, non-fuming and kind to the environment.
GLC Concrete Dissolver will not harm paint, metal, or wood, only Portland Cement.
