SSD stands for saturated surface-dry and it describes a condition that a concrete surface must be brought to when a cement product is to be applied to it. The surface is SSD when the concrete is saturated with water to a depth of several millimeters, but the other surface is devoid of free water, as if it had been dried with a tower.

This surface condition is very important when applying cement products to existing concrete because the saturation prevents rapid drying and weakening of the product and its bond to the surface. Just as important, removal of free water from the surface prevents dilution and weakening of the product in exactly the location where strength is most vital: at the bond interface, Make sure your concrete is SSD before applying all Kryton’s Krystol products.
