Ronacrete Curing Membrane is for use on Portland cement mortars including concrete repair, flooring and renders. It forms a surface barrier, slowing the rate of moisture loss.

The slow loss of water from the surface of fresh concrete or mortar reduces the incidence of cracking and crazing of exposed surfaces, facilitates efficient cement hydration, improves surface hardening and reduces dusting.

Ronacrete Curing Membrane may be used when early overcoating or overlaying of the mortar is to be carried out. Ronacrete Curing Membrane is used in place of damp hessian or polythene and is easily spray applied to surfaces immediately after finishing, when to do so will not damage the surface finish.

Note

Care must be taken to ensure that Ronacrete Curing Membrane does not come in to contact with non-concrete or mortar surfaces, particularly glass or painted surfaces, as it may be difficult to remove and the surface may be etched.

Instructions for Use

Ronacrete Curing Membrane is supplied ready to use; no dilution is required.

Ronacrete Curing Membrane should be applied by low pressure spray to the surface of newly placed mortar or concrete. It should be applied as a fine mist on to the surface; suitable equipment is best determined by site trial.

The entire surface of the mortar or concrete should be covered as soon as possible after placing to provide maximum benefits.

The spray nozzle should be held 30-50cm from the surface and the pressure maintained to provide a fine mist spray. Care should be taken to produce a continuous film and to ensure that the correct coverage rate is maintained. Care must be taken to avoid overuse, exceeding the recommended application rate may affect early overlaying/coating.

Shuttered Concrete

On shuttered concrete Ronacrete Curing Membrane must be applied immediately after the formwork has been struck and any necessary repairs completed.

Wash equipment in clean water immediately after use.
