Description

Concure A99 is a liquid acrylic emulsion membrane curing compound, which when applied to fresh concrete dries to a transparent film of high water retention enabling curing of the concrete by reducing loss of water from the concrete.

Concure A99 is recommended for applications to the surfaces of freshly laid concrete, including renders, structural and mass concrete indoors and outdoors and particularly in situations where other conventional means of wet curing are difficult to maintain.

Advantages

  • Water retention efficiency of 90%. Complies to AS3799-1998
  • Water based and environmentally friendly
  • Eliminates the need for damp hessian, sand or polythene sheeting
  • Rapid film formation
  • Will not yellow in sunlight
  • Economical
  • Seals concrete surfaces

Design Criteria

Concure A99 may be applied to the substrate at various coverage rates to achieve the desired water retention efficiency, however AS3799 requires materials to be applied in a single coat application at a coverage rate of 5m²/litre.

Application rate No. of coats Efficiency (AS3799)

Application Instructions

Stir contents thoroughly before using.

Spray Concure A99 evenly over the freshly laid concrete as soon as possible after final trowelling just after the disappearance of surface bleed water for maximum water retention (approximately 1-2 hours depending on the ambient temperature and atmospheric conditions).

If spray equipment is not available, apply with a soft brush, broom or wide nap roller as soon as the concrete surface is hard enough.

Apply to vertical surfaces immediately after the formwork has been removed.

Apply at an even coverage rate of not greater than 5 m²/litre.

Ensure the concrete surface is completely free of stains, oils, form coatings etc. to obtain good adhesion of Concure A99 and to avoid discoloration or uneven surface effects.

Cleaning

Concure A99 should be removed from tools and equipment with water immediately after use.

Limitations

Concure A99 accepts most after trades however please consult your local Parchem office prior to application of Concure A99 to confirm suitability of after trades. In some instances we will recommend removal of the Concure A99 by mechanical means such as a light grind prior to applying subsequent material.

We do not recommend the use of direct stick timber or parquetry flooring products over Concure A99.

Do not brush on to soft, wet concrete or render surfaces which will be disturbed and thus prevent formation of the curing film.

Concure A99 should not be used as the curing compound for any metallic based integral floor hardeners. Concure CR should always be used with these products to prevent rusting of the aggregate.

Concure A99 is a milky white stable emulsion. Do not use any material which has discoloured. Always first make a test trial application for approval, before proceeding with the job.

Storage

Concure A99 has a shelf life of 12 months if kept in a dry store in the original, unopened packs. Refer to the Use by Date indicated on the packaging.
