The model 8081 Heavy Duty Spray Bar allows for QUICK and EASY application of Multigard® to parking lots, garages and all types of concrete surfaces. No more mixing too much or too little chemical solution because the Spray Bar dispenses directly from the original container. It precisely mixes Multigard® at the desired dilution rate. It is the perfect sprayer for covering large areas quickly and easily. The sprayer connects right to the water supply line. In addition to the spray boom, a hand held spray gun is attached to allow the operator to spray curbs or between obstructions.
