Because they are very durable, you get value for your money when you install an epoxy garage floor. In residential homes, epoxy garage floors can increase the home’s value.

What is an Epoxy Garage Floor?

Epoxy garage flooring is a finishing done to your garage floor by applying several layers of epoxy. Epoxy itself is a thermosetting resin applied on the surface of the concrete. It is formed by mixing the epoxide resin with a polyamine hardener.

This is very different from acrylic paints used to cover surfaces. Epoxy garage floor coatings offer more durability than paint. As the polymer structure is cured, what you have left behind is a more resistant surface.

How to Epoxy Garage DYO Floor-Step by Step

A garage floor made of epoxy can easily be installed.

Clean the garage

Preparing the floor is important for proper epoxy installation. You would need to clean the garage to ensure there are no blockages while working. Remove items, clutter and debris to ensure a free working space. If you would be working around objects such as water pipes, try covering them with a painter’s tape.

After clearing the space, sweep the floor to remove dust and dirt. You could use a brush to thoroughly work the corners of the room. Grease and oil can be removed using soapy water and brush. 

You could also mop the floor to ensure it is free of dirt that might affect the bonding of the epoxy. Try running water from a garden hose to rinse the room off soap and dust.

Prepare the floor

For a perfect look, it is best to ensure your concrete is perfect. If your floor is already painted, you would need to scrape off the paint especially if it is glossy. Once this is removed, you can proceed to clean the floor and mopping it. 

Asides from removing paints, cracks or chips in the concrete floors should be fixed to create a flawless epoxy garage floor. Where this might be difficult, it is always best to start on a fresh concrete slab.

Etch the concrete 

With your bare concrete floor already cleaned, etching it comes next. Etching removes chemicals used to degrease the floor. It opens the pores and allows easy bonding with the epoxy.

Usually, these are acid solutions that come with the epoxy. Start by combining the etching solution and water according to the instructions on it. Scrub the floor after applying the etching solution using a brush or broom. Work on the entire floor. 

You would notice the solution foam as it works on the surface of the floor. Continue till the foaming or fizzing stops.

Etching could also be done mechanically using a diamond grinder, grit blasting using sand or quartz. Once the whole floor is well etched, it should feel like sandpaper. You could then vacuum the dust or rinse off the acid using water from a garden hose.

Mix the epoxy

The epoxy resins for the garage floor usually come in two tins; an epoxy base and a hardener. With the floor set, the next thing is to mix the two tins. Start by stirring the epoxy paint and pouring in the hardener. You might need to keep stirring for about 3 minutes till you achieve a uniform consistency.

In some cases, you might need a bigger bucket to mix the components as the tins might be small. Ensure that the bucket is cleaned so it does not get contaminated. Any other thing you want to add such as an anti-slip can be added here and thoroughly mixed. Most epoxy paints come with instructions that you can use as a guide when mixing.

Apply the epoxy coating to your garage floor

The epoxy coating can be applied to your garage floor once it has been properly mixed. It must be used up within two hours, so move quickly. Higher temperatures might result in less of this. A brush or a roller could be used to apply it. 

It is usually easier to use a brush to paint the corners or the borders. For a larger garage or to move faster, you could get someone to help you mark out the edges with a brush. 

It is easier to work with a 3 inches brush on the outlines and work the insides with a roller. You might want to consider working in sections to keep things easier. Continue till all the floor has been covered. 

Add decorative chips

Once your floor is painted, and you are satisfied with a single layer, you can add the decorative chips if you so desire. To get this done neatly and easily, try applying them as soon as you complete a section. Applying these decorative chips is done by simply pouring them on the epoxy floor.

Let the floor dry

Once you are done covering the floor, allow the epoxy coating to dry. This could take about 24 hours or could vary depending on the weather. Ensure proper aeration to increase the drying rate.

Whether you want to add another layer of epoxy or you want to park your car right on it, allow it to dry. A completely dried garage floor for driving cars can take several days.

Add subsequent layers 

For a garage floor, it is often advised that you apply more than one layer of epoxy. Wait at least 12 hours after the first coat has been applied before applying a second coat. Although drying may take longer, this provides the epoxy floor ample time to be touch dry. 

The clear top coat is the last layer to be applied. The floor now has a polished aspect. Along with the appealing advantages, it offers your floor one more layer of defense.

How Much Does it Cost to Epoxy a Garage Floor

While it might cost more, adding an epoxy garage floor is a nice addition to your home. There is no fixed cost for an epoxy floor. Pricing per square foot could be as low as 0.27 cents and overall cost for the garage could range from between $1,100 and $3,500. The exact amount you would spend however depends on several conditions such as;

  • The size of the garage measured in square foots
  • The preparation done on the concrete or base surface
  • The product to be used
  • The chosen epoxy garage floor paint
  • The amount of coats 
  • Addition of special designs
  • Whether you do it yourself or hire a contractor.

Epoxy Garage Floor Contractors

While you can install your epoxy garage floor by yourself, hiring an epoxy garage floor contractor takes a lot of stress off you. You can find contractors close to you. In searching for an epoxy garage floor contractor, seek out those who are licensed and insured. 

You might also want to check out contractors based on referrals from those who have used their services. Prices of epoxy garage floor contractors vary based on several factors. You should also get a quote before deciding which contractor to go with.

How to Clean an Epoxy Garage Floor

Epoxy garage floors should be cleaned properly to ensure longevity of the floor. To clean your epoxy garage floor, start by sweeping or vacuuming dirt or debris on the floor. 

With the debris out of the way, using warm water and soap, mop the floor. You can use hot water to rinse out the floor if there are residues or oil on the floor. After mopping, dry out the floor using a squeegee.

Avoid anything that could damage the epoxy by puncturing, chipping or scratching the epoxy. When mopping, avoid using an acid cleaner as it could damage the epoxy.
