Let’s dive in.

Polyaspartic Floor Coatings: What’s So Good About Them?

Searching for a durable garage flooring coating that looks great? Polyaspartic floor coatings might be your best bet. 

Here’s a breakdown of their key advantages:

1. Durability & Resistance: Polyaspartic coatings are most notable for their long lifespan, easily lasting 20 years with proper maintenance. They can endure daily foot traffic and abrasive elements and resist chemicals, stains, and spills. These coatings protect your concrete from oil and gas stains and most cleaning products typically found in the garage. They also do an excellent job of protecting against corrosion, moisture, and mold.

2. Flexibility: Concrete floors naturally expand and contract with temperature and moisture variations. Polyaspartic coatings are somewhat elastic and can adapt to these changes. They effectively absorb impacts, ensuring your floor remains free from cracks and gaps. 

3. Temperature Versatility: polyaspartic coatings can be applied in freezing cold temperatures of up to -30°F or sizzling heat of up to 140°F. A fully-cured polyaspartic floor can withstand temperatures of up to 350°F. They’re also UV-resistant, ensuring they maintain their original color and don’t turn yellow under intense sunlight.

4. Easy Repair and Recoating: It’s easy to touch up or reapply a polyaspartic coating. Lightly sand the affected area and apply a fresh coat. The result is a smooth, consistent finish that looks as good as new. 

Overall, polyaspartic’s strength, adaptability, and lasting beauty make these garage floor coatings very popular with homeowners. 

Polyaspartic Coatings: Potential Drawbacks

While polyaspartic coatings offer substantial benefits, there are certain challenges to keep in mind:

1. Application Challenges in Hot, Humid Conditions: High temperatures and humidity can make polyaspartic coatings cure too quickly. This may lead to bubbling or poor adhesion. To avoid this, start your application during cooler times of the day. Always test your concrete floor for moisture, and divide large areas into smaller sections. 

2. May Need Professional Installation: Polyaspartic coatings harden quickly, making it challenging for amateur homeowners to install. It typically requires experienced technicians and specialized equipment, which can quickly increase the cost.

3. More Expensive than Some Alternatives: Generally, polyaspartic coatings are more expensive than epoxy or polyurethane options. Additional factors like brand, installation, and equipment can make it two to three times more expensive than other coatings.

4. Vulnerable to Acidic: Like most garage floor coatings, polyaspartic floors are vulnerable to substances like battery acid. If not cleaned up immediately, these fluids can compromise the floor’s integrity, causing peeling or cracking.

5. Slippery When Wet: The shiny finish of polyaspartic coatings can be slippery when wet. For safety, consider additives for traction, even though they will alter the coating’s look and performance.

While polyaspartic coatings have some fantastic advantages, they also come with concerns. Weigh these factors carefully before deciding on your garage floor coating.

Applying Polyaspartic Floor Coatings: A Step-by-Step Guide

We’ve talked about the application challenges of polyaspartic coatings. Let’s go into more depth on those application process. 

Here’s a streamlined guide to achieving the best results:

Surface Preparation:

  • Importance: Proper surface preparation ensures the coating’s adhesion, performance, and longevity. The result is a clean, dry, textured surface for adequate bonding.
  • Concrete Surfaces: Begin with a thorough cleaning to remove dirt, dust, and grease. Follow up with etching to eliminate laitance or other barriers. Finish with profiling to make the surface rough, enhancing bonding.
  • Tile Surfaces: For tiles surfaces, remove loose or damaged tiles and repair any cracks. Sand the underlying surface for a rough profile, and ensure it’s clean and grease-free before coating.
  • Preparation: Whether you’re using grinding, sanding, shot blasting, or acid etching, choose a method suitable for the surface type and condition. Always check moisture content and pH level to ensure optimal curing conditions.

Application Process:

Speedy Cure Time: Polyaspartic coatings cure faster than alternatives like epoxy. Depending on the desired finish, apply in one or two coats. Typically, foot traffic is possible in 2-3 hours, while vehicle traffic should wait 24 hours.

Application Steps:

  1. Clean the floor using a vacuum or pressure washer.
  2. Optionally, apply a chemical etching agent to enhance penetration, then rinse and dry.
  3. Repair any cracks or imperfections in the surface and ensure it’s even.
  4. Protect areas that shouldn’t be coated, such as walls or cabinets.
  5. Mix the required amount for one layer using an electric drill with a mixing paddle, adhering to the manufacturer’s ratio for each part. Mix carefully without entrapping air.
  6. Starting from a corner, apply the first layer evenly with an 18-inch roller. Use a brush for corners or edges.
  7. Allow at least four hours for the first layer to cure. Ensure it’s tack-free before proceeding.
  8. Apply the second layer similarly. If desired, add flakes or pigments while it’s wet. Use spike shoes for walking on the wet coat if necessary.
  9. Wait 24 hours post-application of the second layer before exposing the floor to vehicle traffic.

Be meticulous in each step. This is the key to a lasting and durable polyaspartic floor coating.

Polyaspartic Coatings: Pot Life

Pot life refers to the duration of time when a mixed polyaspartic coating remains workable before it thickens and hardens. 

This period is critical to the application process. 

Once you exceed a coating’s pot life is exceeded, it becomes challenging or even impossible to apply. This results in a poor-quality finish (at best) or outright failure (at worst).

Polyaspartic coating’s pot life is susceptible to various factors such as temperature, humidity, solids content, and batch size. Each of these factors will shorten the pot life. 

A typical polyaspartic coating’s pot life can range from 10 to 60 minutes. This depends heavily on the amount of solids in the coating. Higher-solid coatings will result in a shorter pot life. 

Some polyaspartic coatings offer a longer pot life than others, making them more user-friendly and suited to different applications. However, they go on thinner and are less durable than higher-solids coatings.

Polyaspartic Coatings: Cure Time

On the other hand, cure time represents the period it takes for a polyaspartic coating to dry and harden completely post-application. 

It is distinct from pot life, which is the duration that a mixed polyaspartic coating stays usable before application.

Like pot life, polyaspartic coating’s cure time is influenced by various factors such as temperature, humidity, solids content, and the coating’s thickness. 

A higher temperature, lower humidity, higher solids content, and thinner coating will shorten the cure time. Depending on the product and the conditions, this can vary from a few minutes to several hours.

Different polyaspartic coatings come with differing cure times. Some dry faster than others. 

The cure time determines when a polyaspartic-coated floor can be exposed to foot traffic, vehicle traffic, or other types of use. Polyaspartic coatings have shorter cure times than epoxy or polyurethane, making them very popular. 

Typically, polyaspartic coatings can handle foot traffic in as little as four to six hours and vehicle traffic in 24 hours.

DIY or Professional Installation: Which is the Best Approach?

When considering a prospective garage floor coating, you must consider whether you want to apply the floor coating yourself (DIY method) or have a professional installation.

Let’s examine each for polyaspartic coatings.

DIY Installation

If you’ve applied a garage floor coating before, then applying polyaspartic floor coatings should be OK for most homeowners. However, since polyaspartic coatings have a short pot life, fast cure time, and high sensitivity to moisture and contaminants, applying them yourself can be challenging. 

Here are the essential steps DIY installers need to follow:

  1. Surface preparation: This includes cleaning, etching, filling, and taping the surface.
  2. Testing: Before application, DIYers need to test the moisture level and pH level of the concrete.
  3. Mixing: Mix just enough material to apply one layer at a time.
  4. Application: Apply the coating evenly and thinly using a roller, squeegee, or spray gun.
  5. Method: Work in small sections and avoid overworking or reapplying the coating.
  6. Second coat: If necessary, apply a second coat after letting the first one cure for at least four hours.
  7. Disposal: Dispose of any unused or hardened material according to local regulations.

Professional Installation

Instead, I recommend that professional contractors install your new polyaspartic floor coating. These pros will have the necessary training, equipment, and expertise to handle the project. 

A professional installation offers several advantages over DIY installation:

  • Efficiency: Faster and more efficient application, resulting in less waste and fewer errors.
  • Quality: Achieving higher quality and durability of the coating with better adhesion and performance.
  • Customization: More design options are available, including different colors, flakes, or pigments.
  • Warranty: Professional services often come with more warranty and protection from the manufacturer or installer.

Do You Need a Top Coat with Polyaspartic?

Whether or not you should add a top coat for your flooring often depends on the floor type, its condition, the look you want to achieve, and how much protection you want. 

A top coat, applied over the base or decorative layer, enhances the floor’s protection, durability, and shine.

Polyaspartic is a versatile coating suitable for various flooring systems, such as concrete, epoxy, or flakes. It’s known for being a high-gloss, fast-curing, and robust finish that effectively resists UV rays, abrasion, chemicals, and stains. 

However, using it as a top coat depends on the substrate’s condition, desired coating appearance, protection needs, and project budget and timeframe.

Advantages of a Polyaspartic Top Coat:

  1. Enhanced Aesthetics: Boosts gloss and clarity, elevating the floor’s appeal.
  2. Protection: Shields the decorative layer, prolonging its life.
  3. Resistance: Offers additional defense against UV rays, chemicals, and wear.
  4. Cost-Efficient: Lowers maintenance and cleaning expenses.


  1. Increased Cost: Polyaspartic tends to be pricier than other coatings.
  2. Application Challenges: Its quick drying time can lead to application errors.
  3. Safety Concerns: It can be slippery when wet, though traction-enhancing additives are available.
  4. Moisture Sensitivity: Vulnerable to moisture and substrate contaminants, possibly causing delamination.

How to Maintain & Clean Polyaspartic Floor Coatings

Polyaspartic floor coatings have the advantage of easy maintenance and cleaning. This is because they’re nonporous, seamless, and stain-resistant, meaning they don’t trap dust, dirt, or moisture like other garage floor coatings will. They also prevent the growth of mold, mildew, bacteria, and odors.

According to Flexmar, polyaspartic floor coatings don’t need waxing, buffing, or sealing because they retain their gloss and durability long after application. 

Cleaning Checklist for Polyaspartic-Coated Floors

Follow these cleaning procedures to make your polyaspartic-coated floor last as long as possible:

  • Regular Cleaning: Use a soft-bristle broom, a microfiber mop, or a vacuum to regularly remove any loose dirt or debris. This will prevent any material that might scratch the surface.
  • Periodic Mopping: Mop the floor occasionally using a pH-neutral cleaner diluted in warm water to remove stains or residues. Avoid using soap, bleach, ammonia, or abrasive cleaners that may damage the coating or leave a film.
  • Thorough Rinsing: After mopping, rinse the floor thoroughly with clean water and dry it with a squeegee or towel to prevent water spots or streaks.
  • Spot Cleaning: If spills or stains occur, it’s essential to spot-clean the area immediately. Use a cloth or paper towel to blot the spill, then apply a suitable cleaner according to the type of stain. For example:
    • Sticky residues like tree sap or adhesives: Use Goo-Gone or Dissolve-It.
    • Tire marks or road tar: Use a carburetor cleaner.
    • Mineral or lime deposits or efflorescence: Use a trisodium phosphate (TSP) solution and water or Lime-A-Way.
    • Oil or grease: Use a grease-cutting agent such as Simple Green or Dawn.
    • Animal feces or urine: Use Clorox Clean-Up cleaner.
  • ProtectionGarage Kings recommends that homeowners shield their polyaspartic floors from direct sunlight, heat sources, sharp objects, heavy loads, and abrasive materials. These can cause fading, cracking, scratching, denting, or chipping.
  • Avoid Covering: Avoid covering your polyaspartic-coated floor with rubber-backed rugs or mats. They may trap moisture and cause discoloration or delamination. Instead, use breathable rugs or mats that allow air circulation and do not contain dyes that may bleed onto the coating.

Polyaspartic Floor Coatings: Color, Finish, and Benefits

Polyaspartic floor coatings offer a broad spectrum of customization for your garage, from color choices to decorative flakes. You can tailor them to match your style and ensure a unique, attractive floor design.

These coatings come in many solid shades, including but not limited to white, black, gray, red, blue, and green. For those who crave a luxurious touch, metallic finishes like silver, gold, copper, and bronze are available.

You can also add decorative color flakes made from vinyl or acrylic. When sprinkled onto the wet coating, this helps create a granite-like or speckled effect. 

Polyaspartic garage floor coatings are applied in one or two layers. First, a primer or base coat is applied, which includes pigments or flakes. Then, a protective clear top coat may follow. This not only adds durability but also brings out the floor’s beauty.

Polyaspartic coatings boast a high-gloss finish that amplifies light while resisting UV rays, abrasions, chemicals, and stains. There’s no need for regular waxing or polishing because your floor keeps its trademark shine with minimal upkeep.

Polyaspartic Floor Coatings vs. Other Garage Flooring Options

When considering garage floor coatings, you may encounter a variety of options, including polyaspartic, polyurea, epoxy, and polycuramine coatings. 

Let’s compare these options to help you make an informed decision.

When comparing costspolyaspartic floor coatings are more expensive than epoxy and polyurea coatings. The cost is more in-line with polycuramine coatings like Rust-oleum RockSolid or EpoxyShield

A polyaspartic coating’s exact cost will vary based on the brand, the solids content, the coverage area, and the installation fees. However, a good rule of thumb is that a polyaspartic coating may cost two to three times more than epoxy coatings.

The volume solids of a coating, or the percentage of the coating that remains on the surface after curing, is also important. Higher volume solids result in thicker and more durable coatings. 

Polyaspartic coatings have very high-volume solids, ranging from 85% to 100%, meaning you can apply them in one or two coats. In contrast, epoxy coatings have lower volume solids, ranging from 30% to 100%, which may necessitate multiple coats. 

Polyurea and polycuramine coatings have volume solids similar to polyaspartic coatings.

Polyaspartic coatings excel when it comes to bonding properties (how well the coating adheres to concrete). They penetrate deep into the pores of the concrete slab to form a strong bond. 

While epoxy coatings also bond well, they don’t adhere as effectively as polyaspartic coatings. Polyurea and polycuramine coatings fall short in bonding properties, as they cure very quickly and don’t penetrate the concrete surface effectively.

Sealing properties, or how well a coating protects the concrete surface from moisture, stains, and spills, also favor polyaspartic floor coatings. They form a seamless, water-resistant seal that prevents moisture intrusion and stains. 

While epoxy coatings also seal effectively, their performance is not quite as strong as polyaspartic coatings. Polyurea and polycuramine coatings tend to underperform in this area. Over time, they can develop issues like pinholes, bubbles, or cracks due to moisture or humidity.

Curing time, or how long it takes for the coating to dry and harden completely, is another crucial factor. Polyaspartic coatings have the fastest curing time among these four options, drying in just hours or less. In comparison, epoxy coatings have the slowest curing time, taking several days or weeks to fully cure. Polyurea and polycuramine coatings have intermediate curing times, ranging from a few hours to a day.

Lastly, consider the UV and color stability of a garage floor coating. This refers to how well it maintains its color and gloss under UV exposure. It directly affects the overall longevity of your garage floor and how it looks as it ages. 

Polyaspartic coatings have the best UV and color stability, as they are 100% aliphatic and do not react with UV radiation. Epoxy coatings, unfortunately, are more likely to yellow and chalk when exposed to sunlight due to their aromatic nature. Polyurea and polycuramine coatings offer variable UV and color stability, which depends on their aliphatic content.

What Homeowners Think About Polyaspartic Floor Coatings

User feedback and real-world experiences are great ways to gauge the effectiveness of polyaspartic floor coatings. Overall, homeowners who have applied these coatings to their garage floors express satisfaction with the results, often favoring them over epoxy coatings.

Specifically, homeowners appreciate polyaspartic coatings for their durability, resistance, gloss, and fast curing time. Many value the additional security of a lifetime warranty offered by some installers.

Easy maintenance is another selling point for homeowners. They report that polyaspartic coatings are simple to clean and maintain, showing no signs of peeling, fading, or yellowing over time.

Customization options available with polyaspartic coatings are also a hit among homeowners. The variety of solid colors, metallic finishes, and decorative flakes allows users to create a garage floor that genuinely reflects their style.

While a few homeowners mention polyaspartic coatings being more expensive than epoxy coatings, they typically feel that the superior quality and performance make the additional cost worth it.

Where to Buy Polyaspartic Floor Coatings

If polyaspartic floor coatings are the right choice for your garage, here are some major suppliers and manufacturers to consider:

  • Resinwerks: Specializing in polyaspartic coatings and other resinous flooring products, Resinwerks offers an online platform for purchasing. They offer three different formulas of polyaspartic coatings, each varying in solids content, cure time, and performance. You can place an order online or contact them for a quote.
  • Armortech Epoxy: Armortech Epoxy provides one-day, fast-cure polyaspartic floor kits suitable for DIY or professional installation. The online supplier offers several color and flake options, free technical support, and a lifetime warranty.
  • Hardware Stores: Traditional brick-and-mortar stores like Home Depot, Lowe’s, Menards, or Ace Hardware also carry polyaspartic floor coatings. However, the selection may be more limited, and the prices could be higher than online sources. You can check their websites or give them a call to see if they have the product you’re looking for.

Wrapping It Up

In this article, we’ve tried to give you a broad overview of polyaspartic floor coatings. There’s a lot of information here – from the benefits and maintenance to customization options and homeowner feedback. Our goal is to give you an idea of why polyaspartic floor coatings can be an exceptional choice for your garage.

Let’s boil the decision down for you:

Which Homeowners Should Choose a Polyaspartic Floor Coating

If you’re a homeowner who values durability, quick installation, and a glossy finish that retains its shine even under UV exposure, polyaspartic floor coatings should be high on your list. 

Polyaspartic floor coatings are also a smart choice if you prefer a seamless, easy-to-clean surface that resists stains and moisture intrusion. If you want to customize your garage floors with a wide variety of colors, polyaspartic coatings will help you do that. 

Which Homeowners Should Avoid Polyaspartic Floor Coatings

Despite these attributes, polyaspartic floor coatings might not be for everyone. 

Homeowners working with a tight budget may find these coatings pricier than alternatives such as epoxy. 

Also, if you live in a particularly wet climate, you may want to select an alternative garage floor coating. Polyaspartic floor coatings can become slippery when wet, making safety a potential concern. 

Finally, since polyaspartic coatings typically have a high-gloss finish, you may want to avoid them if you prefer a matte finish on your garage floor. 

As you try to find the perfect garage floor coating, remember there’s no one-size-fits-all solution. After all, your garage is more than just a storage space or a shelter for your car. It’s a reflection of your home and deserves a floor that complements it in the best possible way.
