HYDROCARBON RESIN EMULSION CURING COMPOUND (Type 1-D, Class B)
Hydrocarbon Resin based curing compound conforming to AS 3799 and Hot Pour Asphalt suitable. SURFACE CURE R is a liquid applied curing compound which consists of a processed blend of petroleum and resin based hydrocarbons. When applied at the recommended application rate Surface Cure R minimises moisture loss in freshly laid concrete thus improving the curing of the concrete providing increased strength and durability and improved resistance to surface dusting. Mainly used on freshly laid concrete floors, carparks, hardstand areas, warehouses, bridge ramparts etc. Also used for curing vertical concrete areas immediately after the stripping of forms to assist strength development, improve chemical resistance, etc.
•Rapid film formation time •Water resistant film formed •Utilises low VOC formula •Complies with GREEN STAR- OFFICE DESIGN V3 IEQ-13 •Economical, ease of application reduces labour cost •Eliminates the need for damp hessian, sand or polythene •Enables concrete to hydrate more efficiently •Increases concrete strength and dusting resistance •Reduces surface shrinkage and cracking •Odourless when dry
SURFACE CURE R should be evenly sprayed (undiluted) over the freshly laid concrete as soon as possible after final trowelling. Ideally SURFACE CURE R should be applied as soon as the surface bleed water has evaporated. Certain adhesives for vinyl tiles, or other types of resilient flooring, and paints of an approved grade may be applied to concrete coated with SURFACE CURE R. It is important however that the concrete should be thoroughly cured prior to such application, and that a test area has been completed for approval. Cement based renders and toppings should not be applied over SURFACE CURE R. First remove the SURFACE CURE R by stripping with STRIPSEAL, EASI-ORANGE or sand blasting or scabbling to provide a mechanical key. The life of SURFACE CURE R will depend on the weather exposure conditions to which it has been subjected; the coating is designed to break down with weathering. Continual exposure to UV light and weather of at least 12 weeks is suggested to facilitate this process. The bond of SURFACE CURE R is likely to fail if the product is applied to concrete or masonry substrates subject to back water pressure, and/or where extraneous salt particles are carried from the substrate to the interface by vapour or condensation. A clear appearance with slight yellow cast is obtained. SURFACE CURE R will oxidize and breakdown when subject to ultra-violet radiation from sunlight. 5 m2 per litre (0.2L/m2) as supplied
