Standards compliance

Reebol complies to category 5: Chemical release agent (Concrete Society: Notes on formwork release agents and coatings. April 1981).

Description

Reebol chemical mould release agent is a specially formulated blend of mineral oils and selected additives. It is supplied as a low viscosity, pale straw coloured liquid.

On the mould, Reebol provides a chemical release action that is superior to that provided by normal oil based release agents (Concrete Society categories 1 to 4). Entrapment of air bubbles at the mould surface is minimized, reducing surface blemishes and substantially reducing remedial costs.

As well as improving cast concrete surfaces, Reebol also minimizes damage to form surfaces. Corrosion on steel moulds is reduced. On all mould types the easier release and reduced residue minimize the chance of damage to the mould surface during stripping and cleaning. This extends the life of the surface and reduces the frequency of concrete defects caused by damage to the mould face.

Properties

Reebol may be used on suitably sealed timber and polyurethane coated, steel, GRP and other resinous formwork surfaces.

Instructions for use

Mould preparation

All moulds, new or used, must be cleaned of surface deposits of rust, concrete, oil or other materials. Inadequate cleaning may lead to surface blemishes due to the adhering material. The use of a proprietary chemical degreaser or acid cleaning with Fosroc Acid Etch*h is recommended.

If only limited use of the formwork is envisaged, new timber moulds may be coated directly with Reebol. If forms are to be regularly re-used then the surface should initially be coated with a suitable polyurethane sealer. This provides increased protection to the timber surface, improves ease of cleaning and prevents the build up of large residual levels of release agent in the timber of the form which may lead, over time, to increased surface dusting or retardation.

Application

Reebol can be applied by all normal methods, including brush, sponge and conventional spray. Where suitable, spray application is recommended.

Non-absorbent surfaces require a single application. New, unsealed, timber surfaces should be re-coated if delay in use of the mould leads to absorption of the release agent into the timber.

Coverage rate

Depending on the porosity and texture of the mould surface, typical coverage rates of 20 to 60 m²/litre (0.015 to 0.050 litres/m²) will be obtainable.

Best results will be obtained with the thinnest practical coating. Over application should be avoided. Excessive application on flat surfaces or which leads to pooling of release agent in the corners of forms is uneconomic and can lead to surface dusting or, in worst cases, surface retardation.

After stripping or demoulding

After use, the formwork or mould should be brushed or wiped clean of any excess dust prior to re-application of Reebol for the next use of the mould. The use of Reebol minimizes the amount of time and effort required for this process.

Repair of moulds

If, after extended use, mould surfaces require repair or recoating with polyurethane sealer, all residual traces of Reebol must be removed to ensure complete adhesion. This is best effected by using a strong industrial detergent together with stiff brushing, followed by thorough rinsing with clean water.

Limitations

For application temperatures in excess of 60°C refer to the Fosroc Technical Department.
