The Moustic : the only true Hand operated mortar sprayer A decoration tool which may be used by all to obtain the most attractive roughcasts very easily, from the finest to the most varied by project of cement, mortars and ready-mixes. We give a full one year warranty (except wearing parts) and all the spare parts to maintain your machine are available in stock. Inside a housing, there is a rotor fitted with stainless steel blades (called "peignes®"). At a certain moment during rotation, these blades are tensed backwards by an adjustable buffer, then, continuing the rotation, these blades are suddenly released and hit a stop device located on the rotor. The purpose of this action is to send the material out of the machine accurately in millions of drops. Using this Locked Trigger® principle, it is possible to make very attractive roughcasts of outstanding quality.
