SHUTTER OIL Marine is a natural Chemical Release Agent. When applied as a thin film on to concrete forms it will react with the contacted surface of the concrete and form a insoluble soap barrier.
These soaps prevent any bond developing between the concrete and formwork, ensuring a clean, even and blemish-free concrete surface.
The fine, Diesel-free, film of SHUTTER OIL Marine allows any air trapped against the form to escape, minimizing bug holes and consolidating surface finishes.
Marine allows better passage of any air. These 'nano chemistry' soaps prevent any bond developing between the concrete and the formwork, and encourage a tightly consolidated concrete surface finish.
