We specialise in using a low pressure sand jetting system that has been used nationwide for property restoration, including gaining approval for and subsequently working on many Listed Buildings. The system, in our trained hands, causes minimal damage to an underlying surface and is flexible enough to tackle most property restoration cleaning tasks.

Bricks can be sealed using Silane products to make it very difficult to reapply graffiti to a surface - paint doesn't stick, and what does can be wiped or pressure washed clean. Subsequent sealing of surfaces can minimise re-occurrence of graffiti, but care must be taken to avoid providing a primed 'background colour' for new graffiti.

The low pressure sand jet can clean bricks without injecting large quantities of water into the surface, and with minimal surface damage, at the same time, the 'damp' system also captures dirt and abrasive, preventing the health and safety risks associated with dry blasting.

A YEDL Electricity Substation in Hull cleaned in May 2004. While Abrasive cleaning is very effective, often graffiti is painted on top of paint, chemical stripping then becomes more appropriate. The customer is happy for the rest of the bricks to be left uncleaned - and we now deliberately leave the bricks dusty after cleaning them it makes fresh paint difficult to apply - reducing the risk of 'retaliative' graffiti

Chemical Cleaning

Sometimes, however, chemical stripping solutions offer a rapid and effective method for graffiti removal - they are particularly useful for removing graffiti from over painted surfaces or from surfaces such as galvanising that may be damaged by abrasives.

Overpainting - metalwork

The Moisture Curing Urethane paints that we typically use on steelwork jobs also have the advantage that although quick drying, they can have an accellerator added which reduces the timescales further. This meant that on a cold winters's day in Goole we were able to overpaint both sides of this footbridge - without getting paint on any of the pedestrians!

Concrete

Obviously typical targets for graffiti are bridges .. this one was local to us. Obviously working on the roadside involves a lot more consideration for Health and Safety, and where necessary Traffic management is used.

Concrete Structures can also be overpainted - this is a fairly inaccessible bridge in the middle of Bridlington!

Where deemed necessary, Anti Graffiti sealers can also be applied post cleaning - this is Mexborough.

Key Benefits

  • 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 is also minimised.
  • Cleaning to the requirements of BS 8221-1&2 :2000 the British Standard Code of Practice for Cleaning and Surface repair of buildings.
  • Quick efficient Graffiti Removal. No interference with other work in area.
