WHAT WOULD MAKE A CLEANROOM UNCLEAN?
Sources of Contamination
• Facilities: – walls, floors, ceilings, paint, coatings, construction material (sheet rock, saw dust etc.), air conditioning debris
• Equipment/Supplies: – Particles from friction and wear, lubricants & emissions, vibrations, brooms, mops, items brought into cleanroom, cleanroom debris
• People: – Skin flakes and oils, hair, spittle (aka saliva), makeup, perfume, debris from clothing (lint, fibers etc.)
• Microorganisms – Viruses, bacteria, fungus
• Particles – Clothing fibers, equipment, paint
Cleanroom Architecture. The elimination of spaces that trap particles.
HOW DO I CARE FOR MY EPOXY OR POLYURETHANE CLEANROOM FLOOR?
Cracks and crevices are where dust and microbes begin to do their damage. Our amazing coatings not just cover small cracks and breaches in your floor, but it eliminates them. Because of our attention to detail when it comes to applying these beautiful, seamless epoxy or polyurethane cleanroom floor coatings, you will have a surface that is extremely easy to maintain. There are NO nooks, crannies, cracks, crevices, clefts, openings, gaps, or holes for dirt or dust to hide.
These are truly high performances coatings for any cleanroom or clean surface. There is no need to wax, or have any other type of maintenance or extra cleaning that is necessary for you to keep you cleanroom up and running.
So please give Sleek Surfaces a call. We would love to show you how one of our epoxy or polyurethane floor coatings can make or keep your cleanroom as beautiful and efficient as you need it to be.
To create a floor that can be classified a truly sanitary floor, it would begin with a surface that is seamless and have a high level of durability. This would mean that it would be resistant to chipping, gouging or pitting that could create areas that can harbor bacteria or other forms of contamination. Our Epoxy and Urethane coating systems not only look beautiful, but they also protect the surface ensuring many years of continual use. These floors are the perfect solution to keep your hospital, surgical area, electronic area, or your assembly floor looking and performing like new for many years to come.
Our coatings can be as thin as 10 mils (about the same thickness as a credit card) and these coatings can be applied to over 150 mils thick. The self-leveling properties of the materials help to hid the imperfections that are very common on concrete floors. What is the result? A beautiful, smooth epoxy or polyurethane clean room floor with no place for contamination to hide. This provides the added benefit to an easy to maintain, long lasting floor.
There is a wide variety of colors that you can choose from. This means that you can have a cleanroom floor that stands out from the crowd. This also gives us the ability to match an existing clean room floor you may already have.

WHY WOULD I WANT AN EPOXY OR POLYURETHANE FLOOR FOR MY CLEANROOM ENVIRONMENT?
HOW IS A CLEANROOM MEASURED?
Achieving a specific cleanroom class requires not only clean physical design (non-particulating materials, etc.) but also a flow of clean, filtered air sufficient to both dilute existing particulates and to drive “dirty” air out of the controlled space.
Fan-filter units (FFUs) are generally used in cleanrooms to provide HEPA- or ULPA-filtered air. FFUs provide air flow at velocities of about 90 to 110 feet per minute, fast enough to generate laminar flow but slow enough to prevent excessive turbulence.Assuming a clean physical design, air flow determines the design cleanliness of a cleanroom. Cleanroom classes, ISO standards in terms of air-changes-per-hour are:
WHAT IS A CLEANROOM, AND WHAT MAKES IT CLEAN?
There are a few characteristics that would go into making and keeping cleanrooms and clean areas… well, clean. The quick and simple answers are as follows:
These are the main factors that go into keeping a cleanroom “clean”. It also helps protect the sensitive equipment and products that are located inside.
The cleanroom class is the number of particles >= 0.5 μm in diameter per cubic foot. For instance, a Class 1,000 cleanroom could contain an average of up to 1,000 particles per cubic foot of space.Actual particulate levels are measured by taking a panel of readings with a particle counter at various points throughout the cleanroom. ###

HOW DOES A CLEANROOM WORK?
A cleanroom provides a controlled, isolated environment for handling contamination-sensitive substances or for protecting the exterior environment from dangerous substances in the controlled area. The density of sub-micron and larger airborne particle contamination inside a cleanroom is kept within tightly controlled limits by forcing clean, filtered air into the cleanroom.
There is a process to controlling particulate contamination. Contaminants are generated continuously by people, processes, facilities and equipment and must be continuously removed from the cleanroom. The allowable level of contamination is dictated by specifications for the operations being performed. In the US, particle counts per cubic foot are commonly given as “class ratings,” such as “Class 1000” specifying fewer than 1,000 particles, with a size greater than .5 μm per cubic foot. ISO standard 14644-1, however, provides more precise standards but is often used interchangeably in the US.Contamination control requires controlling the total environment. Air flow rate and direction, pressurization, temperature, humidity and specialized filtration all need to be tightly maintained to remove particles from the cleanroom. Particles sources must be eliminated whenever possible. ###

WHO NEEDS A CLEANROOM ENVIRONMENT?
There are many industries that require particulate free, scrubbed air environments. From manufacturing to medicine, a wide variety of industrial and scientific processes require the unique environmental atmosphere provided by clean room design, technology, and construction. Anyone who has ever seen the interior of a clean room understands the rigorous controls that prevent the introduction of contaminants into a clean room environment.
Regardless of what type of cleanroom you have, the protocols for maintaining clean room integrity are essentially the same. Specialized garments and footwear must be worn to prevent the introduction of human hair or dead skin cells from contaminating the area—face masks prevent the possibility of cold, flu or other bacterial or virus contaminants from entering the clean room. Environmental surfaces must be of a particular type to resist particulate accumulations, highly specialized gaskets and seals must be used around doors, windows, and other wall perforations. In short, a clean room must remain very clean, indeed. And who needs these super clean environments?
