Typical number of reuses is likely to be in the range of 10 – 15 times. However, the number of reuses will depend on a wide range of factors including good site practice, the required concrete finish, careful handling & storage of forms and the type and quality of release agent.

Form release agents

The selection of the most suitable release agent will ensure cleaner striking of the forms and thus more reuses, as well as better quality concrete finishes. The chemically active release agents are considered to be the most suitable for MDO coating.

Important note: MDO coating is not pre-oiled and must be oiled twice before first use, and thereafter once before each subsequent reuse of the form.
