PRIMAL™ CM 4025 is an acrylic dispersion that was designed to be sprayed onto a finished concrete as a liquid membrane curing compound. The liquid membrane method of concrete curing contributes to inhibit the loss of mix water from concrete slabs. PRIMAL™ CM 4025 Acrylic Dispersion is delivered as a ready-to-use product. Depending on climate and usage conditions we recommend PRIMAL CM 4025 to be spray applied at a 150 to 250 g/m² coverage rate. It should be applied on the clean fresh concrete as soon as the free surface water has disappeared. Characteristics of the product depending on climate and usage conditions and with standard concrete quality: - Contributes to reduction of concrete cracking, scaling, dusting and wind crusting - Replaces water ponding techniques - Contributes to reduction of drying shrinkage - Better contribution to curing vs. conventional waterborne dispersions - Gives clear and water repellent film lasting until primer is promptly applied - Improves abrasion resistance - Serves as a primer for finishing coat* - Low VOC *We recommend running specific trials and checking adhesion properties with special kinds of finishing coatings, such as reactive systems.
