Epoxy coating a garage floor

Ever stepped on a rusty nail in your garage? Or perhaps you’ve got oil stains that just won’t budge? Say goodbye to these problems because epoxy coating is the ultimate solution for a tough, durable, and good-looking garage floor. This post will walk you through the entire process of epoxy coating your garage floor, from prep to finish, along with some handy tips to ensure a great result.

What is epoxy coating?

Garage floor epoxy coatings work well for many garage floors, and for good reason. They’re basically a two-part system—a resin and a catalyst, usually a polyamine hardener—that mix together to form a tough, durable finish. The epoxy resin bonds with the concrete, creating a seamless, stain-resistant surface that’s easy to clean and looks great.

Plus, you can choose from various colours and finishes to match your garage’s style.

How do epoxy coatings work?

An epoxy floor covering forms a robust chemical bond with the surface they’re applied to, creating a durable, protective seal. When you mix epoxy resin and hardener, the chemical reaction causes them to harden and cure. This process allows the epoxy to penetrate the pores of concrete, masonry, or other substrates, locking it in place for long-lasting protection.

The result is a garage coating impervious to different elements, including heat, corrosive chemicals, UV rays, abrasions, scuff marks, and general wear and tear. This makes it an excellent choice for transforming tired concrete into a polished, functional and long-lasting surface in garages.

Epoxy coatings also adhere remarkably well to a variety of materials beyond concrete, including fibre, glass, and metal. Their versatility and durability make epoxy an easy choice for homeowners looking to refresh and protect their garage floors.

6 Benefits of epoxy coatings for garage floors

Epoxy coatings for garage floors offer a number of advantages.

1. Enhanced appearance

An epoxy coating is a significant improvement to the appearance of a garage floor, transforming a plain concrete surface into a sleek and glossy one. The smooth, uniform application creates a polished look that enhances the space’s overall aesthetic.

But that’s not all—you can choose from a variety of colours and finishes, including solid colours, metallic finishes, and even decorative flakes to match your garage’s style.

2. Cost-effective solution

Compared to other flooring options, epoxy-coated garage floors offer great value for money. One application ensures complete coverage and long-lasting durability, eliminating concerns over frequent, costly repairs or replacements. Typically, the cost to epoxy coat a garage floor varies between $5 to $15 per square meter, depending on the epoxy type and project complexity. 

3. Exceptional durability

Busy garage? No problem. The tough, abrasion-resistant finish of an epoxy coating can handle heavy foot traffic and the weight of the vehicles, as well as any dropped tools. Epoxy coatings also resist chemicals, oil, and grease, making them ideal for places where you park or perform repairs on those vehicles—exactly what a garage is.

4. Impressive longevity

Epoxy garage floor coatings can last decades. Many homeowners report that epoxy floors still maintain their vibrant colour and pristine condition even after 20 or 30 years. That said, its lifespan varies depending on factors like the epoxy’s quality, the concrete surface’s preparation, and the amount of wear and tear the floor receives.

5. Superior protection

The seamless, impermeable layer of epoxy coating shields concrete floors from various hazards, including chemical spills, oil stains, moisture damage, and heavy impact. Epoxy coatings also create a barrier that hinders moisture from penetrating the concrete, preventing mould and mildew growth.

6. Remarkable resistance

Epoxy coatings are engineered to resist the elements. They can withstand dramatic temperature fluctuations, exposure to corrosive chemicals, and vehicles’ constant weight and movement without compromising their integrity. They also resist UV rays, preventing fading and discolouration over time.

Preparing the garage floor for epoxy coating

It’s a good idea to prepare your garage floor before you apply epoxy coating properly. Here’s a list of materials you’ll need to get started:

• Concrete cleaner
• A stiff-bristled broom
• A pressure washer (optional)
• A shop vacuum
• A scraper
• A patching compound
• A concrete etching solution
• A paint roller and tray
• A paintbrush
• Masking tape
• Safety glasses and gloves

Applying the epoxy coating

Preparation

If your garage floor isn’t properly prepped, the epoxy won’t adhere properly, and your beautiful new coating won’t last as long. Adequate preparation involves filling all holes, patching damaged areas, removing moisture, and ensuring the concrete is sealed and free of cracks.

Cleaning

The next step is to ensure the concrete is clean and free of dirt, grease, oil, and loose or flaking material.

Vacuum the floor to remove all dust, dirt and debris. Mix a degreasing solution with vinegar or citrus. spray it on oil stains and grease spots, and wipe them with a microfiber cloth. If you’ve got some stubborn stains, a pressure washer can come in handy.

Washing

Etching the concrete with a concrete etching solution helps create a rough surface, allowing the epoxy to bond properly.

Spread an acid solution on the floor evenly and use a stiff-bristled broom to work it into the floor. Leave it for about 10 minutes, then power wash the floor. Once you acid wash and hose down the floor and it’s dry, vacuum it to remove all residue.

Taping

Put painter’s tape or duct tape along the base of the garage door as a boundary within which the epoxy will be applied. Once you tape up the walls and edges, you are ready to paint on the epoxy coating.

Mixing

Improper mixing can lead to an uneven, weak, or brittle finish, so following the manufacturer’s instructions and taking the necessary precautions is essential.

1. Prepare the mixing area: Choose a clean, well-ventilated area and wear safety glasses and gloves.
2. Open the containers: Carefully open the epoxy resin and hardener containers, ensuring you have the correct quantities as stated in the product’s instructions.
3. Pre-mix the resin: Stir the epoxy resin for about a minute using a clean mixing stick or a drill with a stirring bit attached.
4. Add the hardener: Pour the hardener into the resin container, adding the entire amount.
5. Thorough blending: Blend the resin and hardener for at least 3 minutes using a drill with a stirring bit attached. Scrape the sides and bottom of the container to ensure all the material is blended. Observe the manufacturer’s recommended proportions for the resin and hardener to ensure complete blending. Using incorrect proportions or not mixing thoroughly can result in a weak, brittle, or uneven coating.
6. Rest time: Once thoroughly mixed, put the lid back on the container loosely and let it sit in the shade for about 30 minutes. The container might feel warm to the touch as the chemicals react.

Cutting

To create a neat border around your garage floor, use a 3-mm paintbrush to apply a 4-mm line of epoxy around the edges of all walls, extending into seams and corners. This “cutting in” step will prevent epoxy from spilling onto the walls and ensure a clean, finished look.

Application

Now it’s time to roll on the epoxy to your garage flooring!

• Grab your paint roller–you can attach it to a longer pole for easier reach–and then dip the roller into the epoxy tray to start. Make sure only the bottom half of the roller is coated.
• Start in the corner farthest from the exit, working towards the garage door to avoid stepping on wet epoxy. Apply the epoxy to an area of about 1 square metre using a large “W” pattern, ensuring even coverage and watching for air bubbles. Roll the roller back and forth over the epoxy, filling the entire area without leaving roller marks.
• Continue applying the epoxy in corresponding sections until you reach the garage door. Allow each section to dry slightly before moving on to the next.

Remember to work quickly since epoxy cures just as fast. Avoid stepping on wet epoxy by using a piece of plywood or a walking board to move around the garage floor while the epoxy is wet. Keep your roller clean using a solvent or cleaner, as the epoxy manufacturer recommends.

Coating with epoxy flakes

If you’re using epoxy flakes to add a decorative touch to your garage floor, sprinkle them onto each section of wet epoxy. Grab a handful of flakes and sprinkle them liberally over the floor, ensuring even coverage. Some flakes come in containers with shaker tops for easier application. 

You might want to practise your sprinkling or shaking technique outside the garage on a tarp before you start. This will help you get a feel for the right amount of flakes to use and avoid over-application. Once you’re comfortable with the technique, carefully sprinkle the flakes onto your wet epoxy and allow the floor to dry completely.

Curing and drying

Epoxy coatings typically take 24-72 hours to fully cure, depending on factors like temperature, humidity, and the type of epoxy used. Warmer temperatures and lower humidity generally speed up the curing process, while cooler temperatures and higher humidity can slow it down.

Avoid walking on the epoxy floor for at least 24 hours to prevent marring the surface and allow the coating to harden entirely. Always refer to the manufacturer’s instructions for specific curing times and recommendations.

DIY epoxy application or hiring a professional

If you plan to DIY your epoxy garage floor coating, first look at your garage floor and document its current condition. Take photos of any existing cracks, holes, or uneven areas, and even note down any other damage or issues you see. This record will help you track any changes to the floor after you apply the epoxy coating. It could also be helpful if you need to make repairs in the future or if you need to file an insurance claim.

When aiming for a flawless, long-lasting epoxy floor, calling in an experienced professional is often the wisest choice. Professional installers have specialised expertise, state-of-the-art equipment, and dedicated manpower to ensure a seamless application process and a superior-quality finish.

Make sure the person you choose to apply the epoxy coating to your garage floor has the proper license and qualifications.
