Polyurea Joint Fill: Smart and Sustainable for Concrete Cracks

5 Star Rated Company! Get Your Free Quote!

Concrete floors are tough and durable, but they do sustain damage over the years. One of the most common issues you have to contend with is cracks. And for that, you need a concrete crack repair solution that works—polyurea joint fill.

There have been numerous attempts over the years to repair cracks so that property owners can avoid the costly alternative of stripping the concrete and repouring the entire slab or surface. However, not many products did the trick until the industry saw huge advancements in polyurea technology.

Unfilled cracks or indentations expand to collect dust, dirt, and debris, contributing to allergies and other health issues. In facilities that handle food and medical materials, cracks in the concrete can also host moisture-bearing bacteria and provide conducive hideouts for pests.

Do you want more information about polyurea joint fillers? Read on to see how Con-tek Floors wields these fillers to make Colorado properties safer and keep them looking their best.

Digging Into Details: What Is Polyurea Joint Fill?

Joint fillers offer property owners protective material placed in the control joints of existing concrete. What are control joints? These are purposefully-created cracks, symmetrically cut into the concrete surface to allow for temperature and moisture movements.

Concrete is prone to drying and shrinking, so these joints keep your floor in good shape. Polyurea joint fillers are a special type of control joint fillers, which have grown in popularity.

What makes a polyurea filler so helpful?

  • Experts can apply it at virtually any temperature.
  • It boasts short cure times.
  • It offers greater visual appeal than other joint-filling materials.
  • It is durable, handling foot traffic, vehicles, and the demand for forklifts and other heavy-duty machinery in industrial environments.

Polyurea joint fillers are also a great option for increasing your commercial floor’s lifespan. It protects the surface against heavy traffic and prevents the buildup of dirt and moisture. It’s also a popular choice for industrial cooler and freezer applications, curing at temperatures as low as -30°F.

Why Choose Polyurea Control Joint Fill for Your Concrete Cracks?

Polyurea joint fill is versatile. While you can use it on residential floors, it’s also a perfect choice for industrial and commercial settings.

Warehouses and commercial spaces endure tons of abuse daily. If it’s not a forklift or other heavier-duty equipment moving across the floor, it is employees or customers. This continuous traffic creates immense friction and pressure that can adversely impact a floor but not a polyurea.

If you leave control joints unfilled, they’ll soon see the damage. Control joints are the most vulnerable elements of the concrete surface, so protecting them is critical. Filling the joints before they can accumulate detritus, moisture, or bacteria will also ensure the floor lasts longer with little to no maintenance.

Let’s take a deeper look into some of the notable advantages of polyurea joint fillers:

Innovative Fillers Are Durable

Polyurea fillers have proven to be a more robust solution for concrete cracks than many other options on the market. They provide an extra layer of durability, ensuring complete peace of mind that your commercial floor can handle anything thrown at it, including spills and dropped tools!

Polyurea Can Withstand Any Temperature

Colorado has one of the most unforgiving winters. But polyurea is a flooring material that allows application at any time of the year. It can cure effectively in temperatures as low as -20 degrees, whereas epoxy would require waiting for the temperature to rise to at least 32 degrees.

Polyurea Joint Fillers Are Quick to Install

Time is money and every minute counts in today’s construction industry. Every project must be prompt and efficient, and a polyurea joint fill will fast-track your construction project. It cures fast, ensuring your space will be ready for use within an hour from the time of application.

If you go for epoxy joint fillers, you’ll need to wait for at least six hours. And the fast cure times of polyurea also mean spending less on labor compared to other floor coating options.

High-quality Joint Fillers Look Better

Ordinary concrete loses its color over time. While the primary reason for this is constant exposure to the sun’s ultraviolet rays, some interior lights can also affect it. However, you won’t experience this problem with polyurea joint fillers, which have superior color stability.

Your polyurea filler will last longer and look amazing compared to other joint fillers and repair options.

What are concrete coatings?

Our epoxy floor coatings are a concrete resurfacing option that is installed over existing concrete floors for both interior and exterior concrete. All of our coatings are installed by hand (we do not use any stamps), thus giving our clients a true, one-of-a-kind floor. We install a wide range of flooring systems such as: 100% solid epoxy, concrete stain, acrylic cement, and rubber based products.

Clients have the ability to customize any coating with our various color options and design techniques. Concrete Coatings are used not only in residential, but industrial and recreational settings as well. ConTek Coating uses only the highest quality, industrial products on the market to ensure every customer is getting the best value.

How Much Do Your Concrete Floor Coatings Cost?

Each project is customized to your particular concrete flooring needs. Every job we do is different, because we offer different types of coatings and finishes.  We will work with you to develop a free estimate keeping your budget in mind. 

How Durable Are Your Epoxy Concrete Coating Systems??

We use only industrial products on all of our epoxy floor projects. They are designed to give clients the most value and longevity over any other coating material on the market. Just to give you an idea of how strong our products are, we installed an epoxy flake floor in the garage of a Fire Station in 2008 to protect the firehouse’s garage from dirt, debris, salt, and the extreme work environment. Due to our expertise and industrial coatings, we have yet to receive a repair call. Those same products are used in all of our residential projects.

How long does a typical epoxy flooring project take to complete?

A typical residential project takes approximately 3 – 5 days to complete depending on several variables. Variables include, but are not limited to: size of job, repairs and/or preparation requirements, weather, additional design details, customer requests, etc.

What if I already have an existing concrete coating?

We must grind off any existing coating and repair materials before we can install any of our concrete coatings. This ensures the integrity and longevity of our flooring systems.

How Long Do I Need To Stay Off My Concrete Floor Coating After It Is Installed?

If using 100% solids epoxy, your floor will be cured and walkable in about 12-18 hours. You can return to full heavy traffic after about 24 - 72 hours. Wait for at least 24 hours before moving light weight furniture on your brand new concrete coating flooring. Before moving anything heavy (car, equipment and furniture).

How do you prepare concrete for resurfacing?

We start every project by first preparing the concrete for our products. It is imperative that we have a fresh concrete surface before installing our concrete coatings on your project – this will allow our products to have only the BEST mechanical bond.

We spend approximately 66% of the project prepping your floor which may either be by diamond grinding or shot grinding the concrete (depending on the location of the project) and in some cases we do both! Some contractors will come in and just acid wash or not even prep your floor – we get calls all the time about botched installs with customers asking if we can save their project; we must start fresh every time.

Will I Need To Reseal My Concrete Floor Coating?

If you follow our maintenance and cleaning guidelines, you should not have to worry about resealing the concrete floor coating. We offer a professional grade cleaner that will easily remove stains or tire marks, but will also preserve the life of your concrete coating topcoat.

What If My Concrete Floor Has Cracks, Chips And Is Old?

No worries, we are experts in repairing existing problem areas of concrete. In some cases we have been found to be a cheaper alternative over tearing out and replacing existing slabs of concrete. Once we have saved your concrete we then install our decorative designs to hide the flaws and repairs.

How Do I Care For My Concrete Floor Coating?

You can clean our concrete coatings with typical sweeping or mopping. 

Will Oil Stain My Concrete Floor Coating?

Epoxy floor coatings are extremely resistant to most hazards, including cleaners, gas, oil, transmission fluid, and even most industrial chemicals. Our epoxy concrete coatings system is both oil and moisture resistant.

Who Invented Polyurea Coatings?

Andy Phelan, director of business development and training at Rhino Linings Corporation, explains, “Polyurea was invented in the early 1980s when a less moisture-sensitive form of polyurethane was desired. By replacing the hydroxyl group in the urethane with an amine group, a product we now call polyurea was formed.

What Are Polyurea Concrete Coatings?

Polyurea is useful for concrete floors, as it quickly and strongly bonds to concrete while providing a smooth, virtually impermeable surface that protects the floor from impact, water damage, chemicals, heat, and sunlight.

What Types Of Environments Can Epoxy Floor Coatings Be Used?

Epoxy flooring coatings can be used in a variety of environments.  The durability, slip resistant finish is fantastic for any industrial setting, storefronts or garages.

How Are Epoxy Floor Coatings Applied?

We have perfected a six step process for applying Epoxy Floor Coatings that involves prepping the floor, prime floor with epoxy primer, fill all cracks, holes with epoxy grout, then apply epoxy paint. 

Can I Apply Epoxy Floor Coatings In Cold Temperatures?

You can!  Epoxy can be used at cold temperatures but must be handled and applied with techniques adapted to cold temperatures.

Do I Need To Hire A Professional To Install Epoxy Floor Coating?

Installing Epoxy Floor Coating correctly is critical to the appearance and durability of your flooring.  Hiring a professional is the best way to ensure that your flooring will look amazing and last a lifetime! 

Does My Concrete Floor Coating Come With A Warranty?

We provide a 10 year warranty on your concrete floor coatings against peeling, delamination and wear for as long as you own your home.

"Austin applied a polyaspartic epoxy solid-color coating to our garage. The work -- which included grinding off the old coating and the application of three coats of polyaspartic (primer coat + 2) -- was done meticulously. The new coating looks great and the sand added to the primer coat has eliminated the slippery nature of the old coating. Austin was exceptional to deal with from start to finish. He communicated by phone, e-mail & text...always in a timely and totally professional manner. I highly recommend this company."

We recommend and we would use his services again. After the floors were completed he was kind enough to drop off a thank you and some delicious coffee for us try. Thank you Austin!"
