Membrane curing Liquids are solutions of water -resistant resins in hydrocarbon solvents desined to retain water in concrete, improving the curing characteristics, particularly in hot elimates. The materials are supplied in four grades, namely Tempicele F.11 Clear, a 90% efficient material, Tempicele F.11White with similar characteristics to the clear F.11 Grade including a white pigment to act as a heat reflecting shield, and Tempicele F.11 Aluminium pigmented with leafing aluminium flake, which is again designed to reflect heat. A fourth material, which is designated Cemcure EB. 231 is a general purpose membrane with up to 82.5% efficiency designed for low cost applications. Also available with White pigment.

All grades are resistant to the penetration of water and are therefore suitable for application to plaster concrete and if applied at the recommended rate will retain water in the concrete during the setting period and thus facilitate surface curing and the attainment of compressive strength in depth.
Membrane curing liquids also reduce the tendency to surface crazing due to premature drying of the surface and will also reduce the risk of plastic cracking.
They are suitable for application to all types of concrete and if properly applied can be used on vertical.

All grades are one-coat treatment, being spray-applied at the recommended covering rate to the concrete as soon after pouring as possible. With pave work the spraying can be carried out as soon as the concrete is finished and where a concrete train is in operaton the spraying operation should follow the finishing bar.
The materials (Cementone membranes) are of the non-reactive type and therefore will not decompose in contact with concrete bit the durability characteristics of the resins are such that under normal circumstances the coating will weather off quickly as the concrete is put into service.
