Accurate Filling: The electric grouting tool adopts a new circuit design, which makes up for the lack of fluidity and difficult transmission caused by dry, hard, thick and medium fluidity of the mud, and also reduces the trouble of material feeding at any time. . Practical Nozzle: This caulking tool can be equipped with round and flat nozzles to fill holes and joints respectively. And the head of the caulking tool is equipped with an anti-drop buckle, which effectively protects the nozzle from slipping. Labor-saving design: The tail of the grouting machine adopts a labor-saving bearing design, which greatly improves the working stability and discharge efficiency. Flexible and efficient: The electric grouting tool with fully automatic electric design is more convenient to use, flexible and efficient, and easy to operate. The electric caulking machine can replace manual caulking construction, and the work efficiency is doubled. Multiple functions: The pointing grouting machine is multi-purpose, plugging grouting, consolidation grouting, filling grouting, and low-pressure grouting. Available carrier materials: cement mortar, cement grout, white ash, putty powder.
