For my part, for a surface of 30 m2 I only used 3 L of product for have the desired effect. Beware of overdosing, as there is a risk of excessively hollowing out the concrete surface and loosening the gravel. 6 hours later passage of the Karcher under pressure and moderate use !! This product of good brand and to recommend and, is also much less expensive than at the merchants of professional materials !!
