we recommend to extend Schönox AP RAPID PLUS with dry, clean aggregate (aggregate is added last) at a layer of thickness above 2": Type and amount of aggregate used will affect product performance. As qualities of locally available aggregates vary, we recommend to perform tests prior to use on a larger scale.
