Abstract
Apparatus and methods allow difficulty accessible sites of a structure to be sand-blasted. Preferred sand-blasting systems are provided which include a sand-blasting fixture to support the a sand-blasting nozzle and a distal portion of the supply hose in such a manner that the spray of grit particulates may be directed against the difficultly accessible site of the structure. The fixture most preferably includes rigid proximal and distal support tubes joined to one another so as to establish an angle therebetween (most preferably about 90.degree.), and a rigid back-lash support member extending outwardly from the distal support tube. In such a manner, the distal portion of the supply hose is movably supported within the proximal and distal support tubes such that the nozzle positioned adjacent to the back-lash support member may be adjustable by means of the distal portion of the supply hose being further advanced into or retracted from within the proximal and distal support tubes. A clamp member is most preferably provided to positionally fix the nozzle to the back-lash support member.
