Dry Grit Blasting involves firing grit or sand at high pressure to remove old coatings, contaminants, surface laitance etc to give an exposed aggregate
surface for new coatings, or as a surface which can be polished to give a
decorative finish.
Wet Grit Blasting uses water and grit/sand mixed and fired under pressure, this process keeps dust to minimum and is ideal for graffiti removal.
Bush Hammer/Mechanical Brushing uses mechanically powered bush
hammer or rotating wire brushes to abrade the surface to remove contaminants.
Scabbling or Needle Gunning use electric or compressed air to run the
scabbling heads or steel pins in the needle gun nozzle to clean and abrade
surfaces.
High Pressure Power Washing is very effective where contamination is not too serious as it is strong enough to remove surface contaminants without
damaging the original surfaces.
Steam Cleaning normally used with degreasants and detergents to remove graffiti, oil and grease.
Acid Etching uses acid to remove surface contaminants such as cement mortar on brickwork. Whilst very effective it can only be used in very controlled
circumstances.
Chemical Cleaning covers a range of cleaning products selected to best suit the area to be cleaned, client requirements and the environment in which the product will be used. Significant advance in chemical cleaners now mean that softer surfaces such as Sandstone/Portland stone can be cleaned using enzymes to digest the dirt, thus avoiding other cleaning systems which could damage the surfaces. |
