Concentrated and emulsified chemical mould releasing agent.
ECMARELEASE is supplied as a pale amber liquid which turns white when diluted with water to produce a chemical release agent, combining the outstanding release properties of such materials with the economy of conventional oil. It reacts with the alkali in the concrete to form a thin water repellent skin on the surface of the mould which enables easy stripping from the hardened concrete.
No cleaning of unsightly oil stains if plastering is not required. It produces really fair faced finish concrete and can be used on all types of moulds. ECMARELEASE makes cleaning of form faces between pours very easy. It aids corrosion inhibition.
First dilute ECMARELEASE concentrate in the proportion of 1:6 with water, using a clean container and stirring thoroughly until evenly mixed. If the solution is not used the same day, it should be stirred again before use and may require very good stirring after 5 days.
NEW MOULDS: No preparation is normally necessary Metal moulds showing signs of rust, must be wire brushed or treated with emery cloth and burnished clean before coating.
USED MOULDS: Must be thoroughly clean and free from old concrete, dirt, cement laitance, old mould oil and other contaminations. Use a strong detergent for removal of oil and grease.
APPLICATION: Apply the ECMARELEASE 1:6 water dilution to the face of the formwork by spray, brush or cloth. Only one coat should be applied (as thinly as possible except on very absorbent new timber where two coats may be necessary for the first application only) and allow to dry. If the formwork is not used for several days, a further coat may be applied. Only a very thin film of ECMARELEASE should be applied. Excess could lead to surface dusting of the concrete. The best results are obtained by applying with a fine mist sprayer. Where a cloth is used, it should first be soaked in the release agent and then squeezed out well before applying. This ensures the thinnest possible film. ECMARELEASE is not generally recommended where de-moulding is required within 24 hours, although excellent results may be obtained with shorter times.
DRYING TIME: It is essential that the ECMARELEASE is thoroughly dry before placing concrete. Otherwise, being an emulsion, its performance may be impaired. In condition of high humidity drying times will be much longer than in warm dry conditions.
RAIN FALL: It is necessary to protect freshly coated formwork from rain which may dilute the emulsion before it has dried. After drying the coating will withstand an occasional lightly shower but may be affected by heavy or continuous rain. In such cases, a further coat is advised once surfaces have dried out thoroughly.
