The Model 201C Hand Gun allows quick and easy application of Multigard® to all vertical and horizontal concrete surfaces. No more mixing too much or too little chemical solution because the 201C Hand Gun dispenses directly from the backpack; mixing the Multigard® at the desired dilution rate. Dilution rates are controlled by color coded metering tips. It is the perfect sprayer for covering vertical areas and hard-to-reach places and it connects to any available water supply.
