PRODUCT INFORMATION & RESOURCES

DESCRIPTION:

CEMIX A.P.R.A. is an amber coloured, formwork release agent, designed to break the bond between cast concrete and its formwork, allowing for an easy release.

TYPICAL USES:

CEMIX A.P.R.A. may be used on most formwork for concrete casting.

ADVANTAGES:

– Can be safely used on placing tools

COVERAGE:

Type of formwork coverage per litre of product:

– Steel: 30m2 to 60m2

– Smooth Plywood: 20m2 to 40m2

– Rough Sawn Timber: 15m2 to 25m2

PREPARATION:

The substrate should be free of dust, grease, wax, oil, dirt, loose plaster, laitance, curing compounds, paint and all other friable materials and contaminants likely to prevent the adhesive bonding.

The substrate must be dry.

MIXING:

Ready to use. No mixing required.

APPLICATION:

1. Shake / stir before use.

2. Apply a thin coat of product by brush or spayer onto the   

    casting face, back and sides, before each pour or cast of 

    concrete.

Pouring can take place immediately after product application or within 24 hours.

CLEANING:

Clean tools with water immediately after use.

STORAGE & SHELF LIFE:

Up to 12 months when stored in the original, unopened packaging, in a dry place at 2C and 50% relative humidity.

LIMITATIONS:

May stain concrete cast work.

Avoid application of thick coating to new hardboard or plywood formwork, as this may damage the surface finish. Avoid contact with reinforcements, as the product prevents concrete from binding to steel.

The product creates a dust film when it comes into contact with concrete.

Brush film away before any subsequent work is carried out.
