1) What is The Slurry System?
The Slurry System, is a revolutionary, cost effective, and environmentally safe surface
cleaning and preparation method that incorporate HEAT to quickly removes coatings,
oxidation, dirt, and graffiti from most surfaces without damaging them.
2) Why do you say it will do the impossible?
The Slurry System will clean surfaces that are impossible to clean using any other method,
and at speeds that will leave you amazed! It will remove the toughest coatings, yet is easily
adjusted to clean the most fragile surfaces without damage. From removing corrosion on a
battleship to the printed label on an aluminum soda can, The Slurry System does it all!
3) How long has The Farrow System® been in use?
The Farrow System®, was introduced in 1998 to the marine industry in order to efficiently
and safely remove anti-foul coatings from the hulls of boats. The Slurry System controlled
cleaning technique left the fiberglass, wood and steel surfaces of the underlying boat hulls
free from damage and amazingly clean. The range of applications quickly expanded for
the Farrow System® and today it is used around the world as an environmentally friendly
cleaning solution both inside and outdoors.
4) Is The Slurry System safe? How about its environmental impact?
The Slurry System is environmentally friendly and doesn’t use any chemicals or chemical
byproducts. The media is made from 100% recycled glass which is non-toxic which means
that after use, it can be disposed of easily and properly. Dust levels are suppressed within
the vaporized elements of media, therefore allowing this extremely low-pressure cleaning
method to be used safely outdoors, within populated urban areas and even in enclosed
5) How quickly does The Slurry System clean?
After a short set up time of about 15 minutes, precise and evenly textured finishes on
virtually all surfaces are easily achieved in a fraction of time. Initial cleaning procedures are
fast, and surface cleaning speeds are at least twice as fast as outdated abrasive blasting
6) How messy is The Slurry System?
With the controlled accuracy and low pressures used by The Slurry System, little or no
tenting or containment is required to protect adjacent buildings, equipment, or the general
public. The media is easy to sweep up and dispose of when the job is done.
7) Is The Farrow System® a unique process?
Scientific tests have shown that the heat incorporated in The Farrow System® is key to the
speed and precision of the cleaning process. No one else uses heat to clean like The
Farrow System®, and a specifically formulated 100% recycled media. And no one
else can clean what The Farrow System® can clean. The revolutionary Farrow System®
cleaning process is patented throughout the world.
8) Crushed glass sounds like it could hurt me…
Crushed glass is actually the friendliest hard abrasive on the market. It contains no free silica or toxic metals. The recycled bottled glass is manufactured in such a way that it is not sharp on your skin. For instance you can place your hand in the bag, move it around and it will never cut you.
9) I currently use Black Beauty, how does it compare?
Beauty, how does it compare? Recycled crushed glass is a direct replacement for
Black Beauty (coal slag).
10) Is crushed glass dusty?
All abrasives are dusty. However, because most of the glass is clear the dust is actually translucent, allowing for far greater visibility than traditional abrasives. Use in the Farrow System will eliminate 95% of airborne.
11) How can glass be silica-free?
Recycled bottle glass is chemically known as Amorphous Silica, which means it contains less than 1% free-silica. Free-silica is commonly found in traditional blasting sand and other hard abrasive sandblasting medias. Silica-sand dust in its natural state has an “open”crystalline structure that has the capability of sticking to lung tissues. When this happens, the likelihood of developing a serious respiratory
disease called Silicosis increases. Because our recycled glass blast media is amorphous, its crystalline structure is “closed”, which makes it impossible to physically stick to human lung tissue. When a person is exposed to amorphous glass fines or dust, the body will expel the dust as it would any other type of natural dirt.
