The present invention is directed to a sandblasting unit for testurizing objects, and a method of using the unit. The sandblasting unit includes a frame and a housing, with a sandblasting nozzle positioned within the housing. A conveyor belt moves the objects, such as concrete blocks, through the housing for treatment or testurizing by the sandblasting particles. The nozzle emits a spray of sandblasting particles which disperse to cover an enlarged area, with a concentration of particles in a central locale within the coverage area. A protective baffle plate blocks the spray in the central locale so as to eliminate the concentration of spray therein and thereby produce a uniform texturized surface on the object. The baffle plate is adjustably mounted within the housing so that the desired uniformity of texturizing can be achieved. The unit also includes a collection funnel for collecting the used sandblasting particles and vents for suctioning away the waste material sandblasted from the object.
