REQUIREMENT:
High-efficiency concrete curing by a single spray application, without external covering or continuous water application.PRODUCT TO USE:
CALCURE CRHigh Efficiency Concrete Curing Membrane
HOW TO SPECIFY:
All concrete shall be cured by a liberal application of CALCURE CR sprayed onto the surface as soon as possible after finishing or removal of forms at the rate of approximately 5-7 square metres per litre depending on efficiency required. Avoid “pooling”.
EFFECTS:
CALCURE CR is a special formulation incorporating chlorinated rubber which seals the surface of fresh concrete to retain moisture and provide high efficiency curing.
CALCURE CR complies with AS 3799 and ASTM C309-66.
WHERE RECOMMENDED:
All concrete surfaces which shall be subject to traffic during the curing period, and areas to which standard curing methods would be difficult or uneconomical.
After the curing period, preferably at the end of the job, an additional application of CALCURE CR will seal the dry concrete against dusting and facilitate cleaning (For heavy duty sealer, see ROKITE PR).
CALCURE CR is flammable.
NO SMOKING.
NO NAKED FLAME.
Observe all usual precautions with solvents. Use only under well ventilated conditions. Refer to MSDS for CALCURE CR. Do not use in areas where solvent odours may enter building ventilation air intakes or adjacent structures, or affect stored foodstuffs or other material.
NOTES:CALCURE CR is fully compatible with Cementaid ROKITE PR (Clear) penetrating sealer.
CALCURE CR may slightly discolour under prolonged / intense sunlight / UV.
Do not specify CALCURE CR or any other membrane curing compounds when surface hardeners such as Cementaid “DIAMITE” are specified to be used, as penetration of these treatments would be impaired. In such cases, specify water, damp sand or building paper curing.
CALCURE CR provides a “sealed-look” finish, which does not permit bond of subsequent renders or toppings unless the CALCURE CR is removed first.
APPLICATION:
For application Rega Pneumatic knapsack spray is recommended with No. 9, 10 or 11 fantail nozzles. Equipment should be cleaned with solvent based thinners such as Xylol.
