Curecon ‘S’ concrete curing liquid is an aqueous solution of metallic silicates. It assists in the efficient curing of concrete by reducing moisture evaporation from the mix. Curecon ‘S’ forms a micro-crystalline seal in the concrete pores and thereby becomes an integral part of the surface unlike resin-based membranes. The porosity of the concrete is slightly reduced but trials indicate that on both trowelled and cast surfaces there is no loss of adhesion using a number of coatings and treatments. It is recommended, however, that site trials are carried out to check the compatibility of the proposed system.
