Whether you’re a seasoned contractor or a homeowner taking on a DIY project, avoiding common pitfalls is key to a successful application and a long-lasting, stunning epoxy garage floor.
Understanding the fundamentals of epoxy flooring is the first step in ensuring a professional outcome.

Epoxy is a thermosetting resin that is applied as a liquid and then hardens to create a strong, chemical-resistant, and often glossy finish.
It typically consists of two main components: a resin and a hardener, which are mixed together just before application.
This chemical reaction creates a durable bond with the underlying concrete surface, providing a protective and decorative layer.
The versatility of epoxy flooring allows for various colours, textures, and even decorative flakes or metallic pigments to be incorporated, making it a popular choice for both functional and aesthetic purposes.

Essential Equipment for Successful Epoxy Flooring Application
Achieving a professional epoxy flooring finish requires not only the right knowledge but also the right tools and equipment. At Con-treat, we stock everything you need for your epoxy project. Here’s a breakdown of essential items:

5 Common Epoxy Flooring Mistakes (and How to Avoid Them!)
Applying epoxy flooring can seem straightforward, but several common mistakes can lead to less-than-desirable results. Here are five key errors to watch out for:
Mistake #1: Inadequate Surface Preparation – The Foundation of Failure
This is by far the most frequent and critical mistake in epoxy flooring application. Epoxy needs a clean, dry, and properly profiled concrete surface to adhere effectively.
If the surface is contaminated, smooth, or has existing coatings that aren’t properly removed, the epoxy is likely to peel, flake, or bubble.
- How to Avoid It:
- Thorough Cleaning: Begin by thoroughly cleaning the concrete floor. This includes sweeping, vacuuming (with an industrial vacuum cleaner), and scrubbing to remove all dust, dirt, grease, oil, and any other contaminants. Use a concrete-specific degreaser if necessary. Rinse the floor thoroughly and allow it to dry completely – moisture is the enemy of epoxy.
- Profiling the Concrete: The concrete surface needs to be porous enough for the epoxy to grip. This is typically achieved through mechanical abrasion using a concrete grinder. The goal is to create a profile similar to medium-grit sandpaper. For smaller areas, you might use an angle grinder with a diamond cup wheel. For larger areas, a walk-behind concrete grinder is more efficient.
- Repairing Cracks and Damage: Address any cracks, holes, or imperfections in the concrete before applying epoxy. Use a concrete repair compound to fill these areas and allow them to cure properly.
- Moisture Testing: Before applying any epoxy, it’s crucial to test the moisture content of the concrete. Excess moisture can prevent proper adhesion and lead to blistering. Use a concrete moisture meter to ensure the moisture level is within the acceptable range recommended by the epoxy manufacturer.
Mistake #2: Incorrect Mixing of Epoxy Components – The Chemistry of Success
Epoxy is a two-part system, and the resin and hardener must be mixed in the exact ratios specified by the manufacturer.
Incorrect ratios will disrupt the chemical reaction, resulting in a coating that may not cure properly, could remain sticky, or might be brittle and prone to cracking.
- How to Avoid It:
- Read the Instructions Carefully: Always refer to the epoxy manufacturer‘s instructions for the precise mixing ratios and procedures.
- Accurate Measurement: Use accurate measuring tools, such as scales or calibrated buckets, to ensure you are using the correct proportions of resin and hardener. Avoid estimating.
- Thorough Mixing: Mix the components thoroughly using a mixing drill with the appropriate mixing paddle for the recommended time. Scrape the sides and bottom of the bucket to ensure all material is properly incorporated. Inadequate mixing can leave unmixed resin or hardener, leading to uneven curing.
- Proper Mixing Speed: Mix at a speed that is sufficient to combine the components without introducing excessive air bubbles.
- Pot Life Awareness: Be mindful of the pot life of the mixed epoxy. This is the amount of time you have to apply the epoxy before it begins to harden in the bucket. Mix only as much epoxy as you can apply within the pot life window.
Mistake #3: Applying Epoxy Too Thinly or Unevenly – The Importance of Coverage
Applying the epoxy coating too thinly may not provide the desired level of durability and protection.
Uneven application can lead to inconsistencies in the finish, with some areas appearing glossy and others dull, or variations in colour and texture.
- How to Avoid It:
- Calculate Coverage: Determine the square footage of your floor and calculate the amount of epoxy needed based on the manufacturer’s recommended coverage rate (typically expressed in square feet per gallon or litre).
- Use a Squeegee for Even Spreading: After mixing, pour the epoxy onto the floor in ribbons and use a notched squeegee to spread it evenly across the surface at the recommended thickness.
- Back-Rolling: After squeegeeing, use a roller (often a spiked roller followed by a standard roller) to ensure a uniform thickness and a smooth finish. The spiked roller helps to release any trapped air bubbles.
- Multiple Coats: For enhanced durability or specific aesthetic effects, consider applying multiple coats of epoxy, allowing each coat to cure properly before applying the next. Follow the manufacturer’s recommendations for recoat times and any necessary preparation between coats (such as light sanding).
Mistake #4: Ignoring Temperature and Humidity – The Environmental Factors
Temperature and humidity play a significant role in the epoxy curing process. Applying epoxy when the temperature is too low can slow down the curing, while applying it in high humidity can lead to blushing (a cloudy or hazy film on the surface) or other issues with the finish.
- How to Avoid It:
- Check Manufacturer Guidelines: Always check the epoxy manufacturer‘s recommended temperature and humidity ranges for application and curing.
- Monitor Ambient Conditions: Use a thermometer and hygrometer to monitor the temperature and humidity of the environment (including the floor temperature).
- Timing is Key: Avoid applying epoxy when the temperature is expected to drop below the recommended minimum or when humidity levels are excessively high.
- Ventilation: Ensure adequate ventilation in the work area to help with the curing process and to dissipate any fumes. However, avoid excessive drafts, which can introduce dust and debris into the wet epoxy.
Mistake #5: Neglecting Proper Safety Precautions – Prioritising Your Well-being
Epoxy resins and hardeners contain chemicals that can be harmful if not handled properly. Neglecting safety precautions can lead to skin irritation, respiratory issues, and other health problems.
- How to Avoid It:
- Always Wear PPE: As mentioned earlier, always wear a respirator, nitrile or chemical-resistant gloves, eye protection, and protective clothing when working with epoxy.
- Work in a Well-Ventilated Area: Ensure the work area is adequately ventilated to prevent the buildup of harmful fumes. If necessary, use fans to circulate air.
- Avoid Skin Contact: If epoxy comes into contact with your skin, wash it immediately with soap and water. Do not use solvents, as they can worsen irritation.
- Read Safety Data Sheets (SDS): Familiarize yourself with the SDS for the specific epoxy products you are using. These sheets provide detailed information on the hazards, handling, and first aid measures associated with the chemicals.
Troubleshooting Epoxy Flooring Issues and Best Practices
Even with careful planning and execution, issues can sometimes arise during epoxy flooring application. Here are a few common problems and best practices:
- Bubbles: Trapped air bubbles can occur if the concrete was not properly profiled, the epoxy was not mixed correctly, or if the application was too fast. Using a spiked roller immediately after application is crucial for releasing trapped air.
- Fish Eyes: These are small, circular depressions in the epoxy caused by surface contamination, often silicone-based. Thorough cleaning and proper surface preparation are the best ways to prevent fish eyes. If they occur, the affected area may need to be sanded and recoated.
- Uneven Finish: This can result from uneven application or improper mixing. Ensure you are using a squeegee for even spreading and back-rolling with a roller.
- Slow Curing or Soft Spots: This is usually due to incorrect mixing ratios or low temperatures. Ensure you are following the manufacturer’s instructions for mixing and application temperatures.
- Blushing (Hazy Film): This is often caused by high humidity during the curing process. Ensure proper ventilation and avoid application in excessively humid conditions.
Best Practices for Epoxy Flooring:
- Plan Your Project: Before you begin, carefully plan out each step of the epoxy floor coating process, from surface preparation to the final coat, even the basic steps.
- Gather All Necessary Materials and Equipment: Ensure you have everything you need before you start mixing the epoxy.
- Test in an Inconspicuous Area: If you are unsure about a particular product or technique, test it in a small, hidden area first.
- Don’t Rush: Allow sufficient time for each stage of the process, especially surface preparation and curing.
- Consider Professional Training: If you are new to epoxy flooring or tackling a large or complex project, consider enrolling in an epoxy flooring training course.
