Cleaning Systems
Introduction

Not all VESS Restoration Cleaning Systems are appropriate for all materials or surfaces, and extreme care needs to be exercised when deciding which system to use. Before we recommend what is the most appropriate cleaning method or technique for your building we need to understand fully;

  • Your purpose and desired outcomes for the cleaning
  • The exact nature of the cleaning problem
  • The consequences to the building and its surface that can occur using a particular technique

The solution we recommend  may use one or more of the cleaning systems summarized below, or we may need to custom design a specific process and technique for your specific cleaning challenge.

 
VESS Restoration Cleaning Systems

VESS High temperature / Low pressure cleaning System

The VESS high-temperature / low pressure water / steam system is a proprietary system  that is effective at removing many types of biological and other matter from surfaces. This unique system delivers very hot steam or water but as its applied at low pressure it is gentle to the surface being cleaned and will not cause any additional damage to the surface, or waterlog the surface unnecessarily.
When used for the removal of the biological growths such as algae, bacteria, fungi, lichens and mosses, the high water / steam temperatures can kill the spores that cause re-growth. 
High temperature water / steam is also effective in the removal of contaminants such as:

  • Biological growths (such as algae, bacteria, fungi, lichens and mosses)
  • Paint and other coating (including graffiti)
  • Oil and grease contamination
  • Dirt, grime and the build up of pollutants

 

VESS Paint Stripping System

The VESS Paint Stripping system is Unique. Removing either individual layers of paint to reveal original paint or artwork underneath or remove all the paint to expose the substrate underneath.
The stripping technique firstly breaks the bond between the surface and the attached paint. Once the bond is broken the most appropriate systems are used to remove the paint.  Once paint is removed from a substrate a proprietary flushing technique is used to remove all vestiges of the paint right out of the pours of the surface.
Using these techniques paint can be successfully removed without damage and leaving the substrate in a pristine condition from; Wood, Stone, Bricks, Blocks, Oamaru Stone.


VESS Dry Steam Cleaning System

VESS dry steam cleaning uses high temperature dry steam for cleaning surfaces, particularly interior surfaces or where it is important they are cleaned using a dry cleaning technique.

The system converts water to into dry steam vapor with a temperature of up to 180+ degrees Celsius. The temperature and the pressure of the steam can be controlled by the operator so that the surface can be effectively and safely cleaned without damage. Another advantage of VESS dry steam cleaning is that it can be very effective means to clean and sanitize a surface without the need of chemicals.

Very high temperature dry steam vapor  is a very effective means of;

  • cleaning dirt, grime and contaminants from surfaces
  • sanitizing practically any building surface (interior and exterior)
  • killing algae, bacteria, fungi, lichens and mosses and the spores that cause re-growth
  • eliminating mould, mildew and most bacteria, germs, allergens and viruses

 

VESS Cleaning Film System

VESS Cleaning Film is ideal for cleaning surfaces when water can’t be used or the surface is very delicate. This cleaning system is ideal for cleaning and restoring the interior surfaces of stone buildings.  We apply a layer of latex film on the surface to be cleaned, and once cured the film is peeled off along with the dirt, grime, smoke stains, and pollution. This is a very safe system as it will not damage the substrate either abrasively of chemically.

The VESS Cleaning Film system is ideal for restoring internal surfaces. Particularly for building that may have never had there interiors comprehensively cleaned since they were build the removal of dirt, grime and smoke marks etc can restore the interior of the building to as it was when it was new adding new beauty and life to the building.


VESS Moss Prevention / Removal System

Where control of biological growths such as algae, bacteria, fungi, lichens and mosses on the surface of stone is considered necessary for reasons of safety, decay or aesthetics, it can be achieved though;
Controlling surface wetness, by repairing or improving drainage, or encouraging quicker dry-out by reducing the sheltering effects of closely situated vegetation or other structures.
Removal of the growths using the VESS high temperature water / steam cleaning applied  gently at low pressure. Often this technique will not only remove algae, bacteria, fungi, lichens and mosses, but also kill the spores that cause re-growth
VESS biocide washes are also used in the removal of biological growths, as well as in the protection of the surface against re-growth

VESS Chemical Washing Systems

VESS Chemical Washing Systems used for gently washing building and structure. The chemicals used have been developed from exhaustive research and testing.
Our goals being to have chemical wash systems available to use when needed that:

  • don’t damage the substrate and/or its coatings
  • have the desired cleaning properties
  • are environmentally friendly as possible

Our House wash system uses detergents you can wash your clothes with.

The chemical is applied and left to do its work, then rinsed away leaving the surface clean. The advantage of chemical wash systems is the gentleness of the cleaning, no high pressure cleaning or waterblasting is employed, only a soft water rinse is employed

VESS Acid Etch/Clean

VESS Systems have perfected Acid Etching Techniques. These include etching new floors for painting, cleaning and etching old work shop floors to accept painting systems. 

 VESS acid etch new block and brick surfaces to remove mortar/cement that has been splashed around during the building process and creates and even clean surface to accept any coating or to be just left natural.
 VESS Acid Etch can also remove years of efflorescence build up off any surface.
 

 
Protecting Your Building

Why Clean?

The health of a building is not just determined by its appearance but by what is happening on the actual surface itself. Pollutants, contaminants, inappropriate surface coating and biological growths can  degrade building surfaces, which can cause permanent atheistic and structural damage to the building. read more...


Why Remove Paint?

Old buildings when they where built utilised a system for dealing with rain and damp. If the builders utilised a building substrate that allows water vapour to enter but dry out again, or ‘breath’ then this means that damp can dry out harmlessly. read more...


Why Remove Moss?

The growth of biological growths (such as algae, bacteria, fungi, lichens and mosses) and higher plants over monuments and historic buildings can be one of the major problems faced by conservators. read more...
 

Why Clean?

The health of a building is not just determined by its appearance but by what is happening on the actual surface itself. Pollutants, contaminants, inappropriate surface coating and biological growths can degrade building surfaces, which can cause permanent atheistic and structural damage to the building.

Cleaning a building is not just for aesthetic purposes, it is required so the buildings surfaces can be inspected for maintenance or repair. Cleaning is required to remove, coatings, biological growths and other contaminates which are causing ongoing erosion and degradation to the building surface.

Although stone cleaning may result in what is considered by some to be a visual improvement, cleaning carried out by unskilled personnel or by the use of inappropriate techniques can lead to permanent damage to buildings. It is therefore important that the potential risks associated with stone cleaning methods are fully understood by the building owner, the architect, engineer, contractors, and building conservatory / heritage bodies.

We often are called into advise on buildings that have been damaged by inappropriate cleaning processes,  in some case we can restore unfortunately in many cases the building is irreparably damaged. We can offer technical advice if you are planning to clean your valuable building or if previous cleaning has damaged your building.

Why Remove Paint?

Old buildings when they where built utilised a system for dealing with rain and damp. If the builders utilised a building substrate that allows water vapour to enter but dry out again, or ‘breath’ then this means that damp can dry out harmlessly. Old building usually rely upon surfaces and mortar joints that allow ‘breathing’, it is  when the porosity of a surface is altered that problems with dampness and degradation of the buildings surface and structure can occur.

Most modern paints and coatings are in many cases an impermeable coating  these applied materials are incompatible with the soft, porous and moving structure beneath. Non porous coatings will lock moisture in the walls, and if the coating develops tiny cracks, as a result of movement or of loss of adhesion, then water could enter and begin the process of decay: evaporation is concentrated at cracks where any salts present crystallize, causing decay.  Damp patches may appear on the inside wall as more moisture is forced to evaporate here.

Paint, by inhibiting the drying action of the exterior surface of the building, will itself encourage the rapid deterioration of Stone surfaces and age them by generations in a few short years.
If you are planning to paint a heritage building particularly with a stone or masonry surface contact us and we can advise on the suitability of your plans.

If your stone or masonry building is already painted, this may  need to be removed to restore the integrity of the buildings system for dealing with water and damp, and to halt any further degradation or damage to the building.

Why Remove Moss?

The growth of biological growths (such as algae, bacteria, fungi, lichens and mosses) and higher plants over monuments and historic buildings can be one of the major problems faced by conservators. They will colonise stonework wherever conditions of moisture, light, temperature and nutrition are suitable. A general indication of stone requiring treatment is when mould, moss or lichen begins growing on the surface, causing green or greyish discolouration of the stone. Dark soiling on a surface is often equated with particulate soiling when closer inspection would reveal soiling of a biological nature

Biological growths as well as being often atheistically unpleasing, can trap dirt particles from the atmosphere, as well chemical react with the surface increasing the rate of soiling or damage of the building surface, and aiding the establishment of higher plants. These in their turn may increase water retention and block gutters and downpipes, leading to further defects.

Damage to stone may be caused or initiated by the presence of biological growths, and if these growths are contributing to the deterioration of stone, there removal is necessary to halt the process of erosion and degradation of the building surface.

Where control of growths on the surface of stone is considered necessary for reasons of safety, decay or aesthetics, it can be achieved though;

 

  • Controlling surface wetness,
  • Removal of the growths using high temperature water / steam cleaning applied gently at low pressure. Often this technique will not only remove algae, bacteria, fungi, lichens and mosses, but also kill the spores that cause re-growth
  • VESS biocide washes are also used in the removal of biological growths, as well as in the protection of the surface against re-growth
