This article explains step by step how to apply an epoxy resin floor coating for the garage and what you should pay attention to.




Epoxy garage floor cost and advantages – Why is a 2k garage floor coating the ideal solution?

What is an epoxy resin floor coating? Epoxy resin is a form of plastic that is divided into two components. These combine chemically with each other and form a solid surface after curing. It is also possible to incorporate decorative chips and flakes.

How expensive is a garage floor coated with epoxy resin? The Epoxy garage floor costs depend mainly on whether the coating is carried out in-house or whether a professional takes care of it. In general, prices start at around 24 cents per square feet. For a parking space of about 500 square feet, an epoxy resin coating costs about 120 Dollars.

As soon as a professional company takes over the coating of the floor, a few hundred euros are added. In the end you will pay about 1’000 Dollars for the complete coating of the floor with a professional. The price also varies depending on the layer applied, the area covered and possible travel costs.



Advantages of the garage floor coating made of epoxy resin

What about the advantages of the coating? Coating the garage floor with 2k epoxy resin does not only create a beautiful sight when entering the garage. Especially 2k coatings provide practical, slip-resistant properties due to the additives they contain.

The coating is also useful for long-term protection of the floor. This protection can include various chemicals, oils, liquids, road salt and petrol. As a result, you benefit for a long time from an attractive and easy-care surface for your vehicle.

In summary, the 2k epoxy resin offers numerous advantages as a garage floor coating:



  • quick and easy to process
  • Protection against plasticizers from tyres
  • Protection against liquids (petrol, oil, chemicals, liquids and condensation with road salt)
  • very resilient
  • wear-free
  • jointless
  • easy-care


You may find the long drying phase and the time-consuming application procedure to be disadvantages. In addition, coating a complete garage floor with epoxy resin is not necessarily favorable. However, as soon as the coating is finished, the garage floor will be an easy-care, durable and robust base for your vehicle.

To make sure that the garage floor coating made of epoxy resin is successful, it helps to have instructions ready. Basically, you should only apply the epoxy resin in the quantity you actually need. Once the resin has bonded with the hardener, you should not dawdle any longer! If the coating is not applied quickly enough, the resin will harden before you have finished your work.

With the help of the following step-by-step instructions you can easily coat your garage floor with the 2k epoxy resin. You need the following materials:


  • Primer
  • Epoxy resin coating for floors
  • Brushes
  • Nailed shoes
  • Agitator
  • Sealing
  • Roll for sealing
  • Bucket
  • possibly a vacuum cleaner
  • Detergents
  • if necessary, hammer, spatula, steel brush


Depending on your personal taste you can also provide decorative chips or glass beads. Here it depends above all on how the floor is to look afterwards.


Material needed to make a garage floor from epoxy resin

The most important material is the special epoxy resin, which was developed for the garage floor coating. Here there are different qualities and both colourless/transparent and already coloured products. The quality of the material is important – here you should definitely not save money and buy an epoxy resin of inferior quality, as this is decisive for a successful floor covering.

4. Epoxy resin colors, decorative flakes and glass granules

A suitable colour should be used to colour the resin. Additional colour accents can be achieved with decorative flakes that are sprinkled into the still wet resin. Glass granulate is particularly suitable for making the substrate non-slip.


5. Tools need for your epoxy resin garage floor

Epoxy resin is easiest to apply either with a large scraper or a lint-free coating roller



After the actual spreading process, a venting roller is run over the entire surface again to allow any air bubbles to escape and level the surface.

Larger quantities of epoxy resin and hardener should ideally be mixed in a large container. A powerful drill with a stirring attachment is suitable for this purpose.



6. Occupational safety when coating your garage floor

When working with epoxy, you should follow basic safety precautions to avoid endangering your health. This includes wearing nitrile gloves and safety glasses. To be protected against possible vapours escaping, it is also advisable to wear a breathing mask with an appropriate filter.



Step 1: Check garage floor for moisture and oil stains

Damage to the floor ensures that the coating cannot be applied completely smoothly. For the epoxy coating to work, the floor in the garage must be completely exposed. At the same time, oil stains and moisture must be detected before the actual work begins.

Porous spots in the concrete are a risk for the coating of the floor. Check with a hammer and steel brush to see if any components come loose from the floor. If this is the case, it is advisable to grind the garage floor before coating. In case of extensive damage, it is usually worth replacing the entire concrete before the epoxy resin is used.


Step 2: Cleaning the garage floor

The inspection of the garage floor usually already reveals weak points. Dirt, dust and oil stains in the garage also play a role. In order for the coating to harden properly later, you must clean the garage floor.

A spatula is helpful for cleaning the floor. This can be used to remove stubborn dirt and dried paint stains. Afterwards, a vacuum cleaner helps to remove dust and loose dirt. Make sure to remove oil stains with a suitable oil stain remover.

Finally, for this step it is recommended to treat the garage floor with a water hose or high-pressure cleaner to remove the remaining dirt. If you then notice dirt in the garage, you can try a special cleaner for concrete floors.


Wichtig: The floor must dry out completely after all cleaning work! An airtight plastic foil indicates condensation water if necessary. Freshly laid concrete floor needs at least 5 weeks to dry. Coating can then begin.


3rd step: How to epoxy garage floor – Priming the garage floor

Epoxy resin as a coating for the garage floor may require a primer. This primer is especially necessary on a substrate that has highly absorbent properties. This procedure ensures that the substrate for the coating is waterproof. How do you proceed?

Use a paint roller to spread the priming coat on the floor as you would when painting. Make sure that the applied strips do not overlap. Once the primer has been applied, wait for a minimum of 12 and a maximum of 48 hours. This is how long the primer needs to dry.

Especially in hot summer, priming the garage floor can be difficult: Warm air naturally contains more moisture than cold air. The garage floor is about 15° C cooler, which in turn can cause condensation. The problem with this is that when the primer dries, the condensation water sometimes causes unsightly stains. To ensure that everything runs smoothly, a temperature of 16 to 23° C is recommended. Caution: The floor should have a temperature of at least 10° C so that the work can be carried out cleanly.

Step 4: Mix epoxy resin

Before you can use the epoxy resin, you must mix it according to your needs. To do this, mix the 2 components of the epoxy resin (resin + hardener) in a ratio of 2:1. A stirrer makes it easier for you to mix the two elements. Stirring is particularly important to ensure that the mixture is uniform and has good resistance at the end.

After mixing the two components, it is advisable to wait 10 minutes. During this time the remaining air will escape from the mixture. This prevents air bubbles from forming in the coating.

Step 5: Apply epoxy resin to the garage floor

Once you have mixed the epoxy resin, time is of the essence. The resin usually has a drip time of 2 hours. During this time you must have spread the mixture on the garage floor to prevent it from hardening before then. A stopwatch or a timer in a mobile phone is suitable for this purpose.

You can apply the mixture in the corners with a brush. For the rest of the garage floor, it is best to use a short-hair roller. The epoxy resin is applied in strips – just like painting a wall. Ideally, these strips should overlap evenly to create a uniform layer. The layer must then dry for 12 hours.

Step 6: Scattering of decorative flakes or chips

Those who find the normal layer of epoxy resin on the floor too inconspicuous can fall back on decorative flakes or colour chips. You will need a pair of gloves for these colour accents.

The scattering of the colour particles takes place directly after the coating. Grab some of the chips with your gloved hand and spread them evenly on the floor. If you like it fancy and have a knack for art, you can also arrange the decorative flakes in a certain pattern. In addition to the colours black and white, the trade offers a large selection of colour chips.

Step 7: After bedding: Sealing the floor

Is a sealing of the garage floor afterwards even necessary? What do you need a sealing layer for? The additional sealing is particularly worthwhile if you have scattered colour chips. But a sealing layer can also be helpful without colour accents in the coating. Because without sealing the epoxy resin layer, sharp edges can remain. These can be softened or even completely smoothed out with the sealing.

Note: Excessive gloss on the layer may indicate that the coating has been applied too thickly. In this case the epoxy resin or sealing compound should be spread further on the floor.


Step 8: Drying and curing

Before you can use the garage floor for yourself and your vehicle, you must wait. The coating must cure completely to make it strong and resistant. An ideal temperature of 20° C is recommended. A relative air humidity of 65% does the rest to make the material harden.

How long does it take before you can walk on the garage floor? The coated floor is generally accessible after 24 hours. But be careful! Walkable means not passable. A car weighs considerably more than a person. Accordingly, the coating of the floor may be sufficiently cured for one person after one day. For a vehicle, this period is not enough.

To ensure that the coating can withstand the load of a car, wait a week. After 7 days at the earliest you can drive a car into the garage. It is better to wait 12 days. This period of time requires some patience. However, it is worth the wait. If you act too early at this point and put too much strain on the floor, you risk unsightly marks and uneven dents in the resin layer.


Last step: Maintenance of the finished epoxy resin garage floor

Once you have followed the previous steps, the coating of the garage floor is complete. Under normal use, the coating will last for approximately 4 years. After that it is advisable to renew the coating. In the meantime, you can easily maintain the epoxy resin floor.

Sweeping, wiping, vacuuming as well as cleaning with a high-pressure cleaner is possible without any problems. Sanding the floor in the meantime is usually not necessary. The coated surface reliably repels dirt, oil, water and road salt.
