Paint removal using methylene chloride or dichloromethane (DCM)

DCM is an organic compound with the formula CH2Cl2.  DCM’s volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes.  It is widely used as a paint stripper for the removal of paint from masonry substrates.

JOS Cleaning Technology

Heritage Stone Restorations Pty Ltd specialises in stone cleaning techniques using the latest JOS patented chemical-free, low-pressure, rotating vortex process. It works gently and it works effectively.

The cleaning technology operates with an extremely low, and variable, air pressure (between 0.1 and 21 PSI) which can be regulated with water and an extremely fine granulate such as calcite.

JOS cleaning technology can also be used to remove old layers of paint without the use of chemicals, clean natural stone and tiles, remove fire damage, clean off oxidation on bronze, brass, copper, anodised aluminium and other surfaces.

This system is in use across Europe and has been used on prestigious projects in Australia.
