Curing Compound Fosroc Concure PI - 20L Concure PI is a membrane concrete curing compound. It provide a film of water retention enabling curing of the concrete by reducing water loss from the concrete. Membrane Concrete Curing Compound Uses Provide a film of water retention enabling curing of the concrete by reducing water loss from the concrete. Advantages Reduce surface shrinkage and cracking by eliminating moisture loss from exposed surfaces To help concrete hydrate more efficiently Easy to apply thus saves times and labour cost Eliminates need for damp hessian, sand or polyethylene Description Concure PI is a liquid membrane curing compound based on high grade silicate compound, clear in color and when cured form a thin clear film. Concure PI complies with ASTM C 309 - 97 Type 1. Properties Color : Clear Liquid Specific Gravity @ 25 C : 1.10kg/ltr Dry film colour : Clear film Dry time (approximately) : 1 - 2 hours Application Instructions Before using stir Concure PI thoroughly. Spray Concure PI evenly as possible over the freshly concrete as soon as possible after final towelling when the surface water has disappeared. If spray equipment is not available, apply with soft brush, broom or wide nap rolled as soon as the concrete surface is hard enough. For vertical surface, apply Concure PI immediately after the formwork has been removed. Apply at an even coverage rate of not greater than 6 sqm per litre.
