Like with bricks, the sand jet will only blow out loose pointing. In general re-pointing is unnecessary after using this process. 

 

 

Paint can be just as effectively removed from stone, as from brick.
  • The low pressures mean that the system is gentle enough to clean delicate surfaces, yet powerful enough to strip multiple layers of paint in one pass. 
  • It is not a chemical process so no noxious or harmful slurries or fumes are generated. 
  • As it uses only minimal amounts of water and abrasive the system is regularly used indoors.
  • Considerably less mess than other systems, the low pressures mean that secondary mess (dust being blown out of floorboards etc) is also minimised.
  • Has successfully cleaned stone, bricks, metal, hard woods and fiberglass. Quick efficient Graffiti Removal. No interference with other work in area.
