Polyurea Food Grade Coatings

by on February 05, 2021

Keeping food-processing plants and beverage facilities clean and sanitized is a challenge. The goal is to find the simplest way to protect the elements (floors, walls, ceiling, gate, posts, and rails) during the cleaning process while maintaining sanitary provisions. 

Sprayed on FOOD GRADE COATINGS can decrease maintenance expenses because it’s quickly cleaned by pressure washing without the anxiety of being destroyed by the cleaning process. Polyurea is applied as a liquid that turns solid in 5-8 seconds. It is astonishingly tough and can easily withstand excessive temperatures from -20F to more than 300F. 

Several polyurea systems are available for potable water applications and are FSA and USDA-acceptable and NSF-approved to ANSI-NSF 61 standard for potable water storage; meat and dairy butcher shops, processing plants any other food processing application.


Floors: Polyurea food-grade coatings are ideal for food and beverage industry floors because it provides a seamless, durable, low-maintenance, sanitary, safe, non-slip surface that is temperature resistant (can resist extreme hot and cold temperatures), and cures fast. The floor and walls are easily coated with a monolithic, seamless lining system. Sharp corners, nooks, and crannies can be filled with a bridging polyurea foam and then top-coated with a solid polyurea to create an easily cleaned surface profile.


FREEZERS: Polyurea is ideal for refrigerated storage facilities, freezers, and food- processing plants where time and temperature are driving concerns.


Equipment: Food processing equipment can be coated with polyurea food-grade coatings to give an abrasion-resistant coating that, unlike paint, will not peel off and can hold up to the rigors of daily cleaning.


Silos: Polyurea food-grade coatings can be sprayed straight onto the silo, creating a permanent lining system. It also creates a great seamless flooring system.

Food Preparation and Processing Area Coatings

It's crucial to understand the USDA requirements for processing, preparing, and storing food. Listeria bacteria diverges from most bacteria and can multiply in refrigerated temperatures. Listeria can be deadly to the old and young, so it's no wonder the U.S department of agriculture has declared a zero-tolerance attitude towards its presence.


Cleaning is an essential part of the process of food processing plants, and the easier the exterior to clean, the more bacteria will be cleansed from it. Cracks in the paint, rusted areas, or exposed concrete are areas that bacteria will thrive and reproduce. Covering up these areas is only a short-term solution to what can be a long-term dilemma.

USDA FDA and FSIS Approved Systems

Polyurea coating systems are a multi-coat USDA, FDA and FSIS approved system that is hard-wearing, seamless, smooth, and aids in diminishing bacteria. These systems are fast to install by trained and certified applicators, and they can often complete a full processing plant in less than four days.

These systems' properties allow it to work perfectly in a temperature range of -25° F to 230° F. It's extremely hard wearing and being seamless; it doesn't allow for any cracks or crevices that bacteria could build upon.

Reshaping Processing Plants Using Polyurea

With news of more food processing facilities pulling product off the market and having to shut down due to possible contamination from Listeria Monocytogenes, the concern of plant sanitation, as well as style and building structures, are at the forefront of the agenda for those in the industry.

At issue are food and meat processing plants located in aging industrial buildings with extensive ware and tear, in addition to ideal angled building. In these plants, walls and ceilings are typically built with angled steel, i-beams, concrete block, interlocking metal and fiberglass panels, double-t ceilings and tiles with concrete grout.

This supplies a virtual breeding ground for standing water, dirt, dust, mold, and pathogens such as Listeria, E. Coli, and Salmonella. With many fractures, pits, and seams, plants are at danger in spite of aggressive power cleaning and chemical sanitation strategies.

Plant Recalls from Listeria
The fallout from a public recall due to Listeria extends well beyond lost earnings and extended plant shutdown as well as a decrease in overall business value. Lawsuits, due to customer health problem and even death, along with the disastrous impact to the brand name's credibility, can put a processor out of service.

The difficulty with Listeria is that it is proficient at evading detection. It can aerosolize or connect to equipment and individuals, and will prosper in cold temperatures. As an outcome, it is difficult to control in the processing environment. To fight this pathogen, lots of centers depend on a robust sanitation program to avoid Listeria from getting in or polluting the environment. In addition, many processors participate in continuous environmental sampling programs to keep track of the efficacy of those efforts.

If any bacteria or contamination is discovered, called "testing hot," it can lead to an instant shutdown. Closing down a food processing plant that is running 24 hours a day, 7 days a week, can cost the processor millions in lost profits. There is also the danger of fines by the USDA for recurring violations.

In the majority of instances, business just react to a positive test by performing magnified cleaning and sanitization. Once the company's follow-up tasting of the affected websites is negative, the problem is normally thought about to be dealt with.

In addition to issues about bacteria, contamination likewise comes from facility maintenance concerns, such as breaking paint, spalled and broken concrete, and areas in the walls and ceilings that can gather dust, dirt, mold and other contaminants.

Perpetual Cleansing, Painting
Until now, the expensive and labor heavy solution was merely to clean up more frequently and mitigate the issues utilizing FRP panels or layer upon layer of paint to try to create a cleanable surface.

The aggressive cleaning agents like bleach and cleaning agents and heavy high pressure power cleaning cycles take a heavy toll on the paints, epoxies, concrete, fiberglass and metal surfaces eventually use them away until they need a total replacement, or even worse, they jeopardize a plant shutdown and or fines.

This is an extremely costly, labor-intensive program that duplicates itself in perpetuity at practically every food processing plant throughout the nation.

To resolve this issue, new patented techniques are being used to deliver a complete rehabilitation of the walls and ceilings, typically throughout planned maintenance weekends.

Many other coatings take 1-4 days just to treat, which is too long when you require to get the plant back online. Polyurea cures within minutes. Additionally, the space is "reshaped" through this procedure so just smooth, curved lines stay to remove areas where water, dirt, grime or pathogens can collect.

Among the key elements of the industrial process is application of an incredibly fast curing, pure polyurea coating designed for usage in food processing plants. Given that the material is spray used, it can be applied quickly by qualified applicators and constructed up to any required thickness and formed into the modified wall and ceiling design. Polyurea is the only coating system readily available that can create a monolithic surface area in the brief time frame needed to minimize plant downtime.

The majority of other coatings take 1-4 days simply to cure, which is too long when you need to get the plant back online.

Companies makes use of a special, private label formulation of pure polyurea for food contact facilities from ArmorThane, a worldwide provider of high-performance polyurea coatings, liners and joint sealants for a wide variety of industrial environments. The company uses two systems that are third-party ranked for FDA Direct Food contact.

Due to the aggressive nature of plant wash downs, a custom-made polyurea topcoat is required to finish the process., The final topcoat creates a very slick surface, making it difficult for standing water, dust, dirt, or bacteria to take hold. To finish all this work, Companies deal with the food centers to strategize and optimally time rehabilitation operations.

Before any coatings are used, there are several actions to restore an aging food facility., No quantity of cleansing will effectively prepare a surface that needs repair. So the initial step is to resolve any areas with spalled or split concrete, chipping and peeling paint, or heavy corrosion.

The next action is an intensive cleaning process to remove grease and gunk and other surface area contaminants that build-up as an outcome of meat processing, cooking, and basic facility maintenance. This involves using specially authorized wash down options and self-contained high powered water blasting techniques. All holes, voids, joints, and penetrations are filled, along with additional adjustments for the reshaping. A combination of concrete and molded foam products are utilized to transition any flat surface areas from 90 degrees to 45 degrees to avoid standing water from accumulating.

These areas usually consist of the cove joint from wall to floor, steel I beam bases, welded and frame bolted angle iron, and gaps in the existing construction or wall/ceiling fascia. Standing water is one of the numerous contributing aspects for Listeria and other pathogens, in addition to mold and corrosion. Finally, every piece of devices, pipe, flooring, and other exposed locations must be wrapped in plastic or covered prior to spraying starts.

In numerous applications, such as the within of big tanks, sprayed polyurea is not required to be cosmetically appealing.

For food processors in aging centers this type of total interior wall and ceiling rehabilitation-- regardless of the surface or substrate and level of disrepair-- might be the quickest method to break the cycle of constant degeneration and ongoing repair, while decreasing danger of pathogen-based item recalls.
