Guest Author:  Pearl de Guzman

Have you ever wondered how to fix or revive a worn-out concrete garage floor? The answer might be more straightforward than you think. 

It is possible to restore your old, stained concrete floor with some new sealant. Many DIY projects will help you revitalize your old concrete and make it look new again. 

The concrete floor in your home or office is one of the essential surfaces in the entire space. It’s important to make sure that it’s always in good condition to provide years of service.

However, sometimes a concrete floor can become worn out and need rescue. If this is the case for you, don’t worry! You can do several things to restore your concrete garage floors to their former glory.

In the article below, we have compiled a step-by-step guide to show you how to properly prepare your surface and apply a sealant so that your floor looks new, brighter, and more expensive.

What Is A Worn-Out Concrete Floor?

A worn-out concrete floor is a surface that has lost a lot of its original luster due to wear and tear and has become damaged over time.

If you have a damaged concrete floor, don’t worry! There is still hope. With a bit of effort, you can revive your concrete and make it look new again.

Why Do Concrete Floors Wear Out?

There are a few reasons why a concrete floor might wear out. Here are some of the most common reasons:

Stains From Spills And Tracked-In Dirt

If your concrete floor is constantly stained from spills or dirt that is tracked in, it can become difficult to clean and maintain. Over time, this build-up of dirt can cause your floor to lose its luster.

Wear And Tear From Foot Traffic

Foot traffic is one of the most common causes of wear and tear on a concrete floor. If your floor is constantly being walked on, it can become scratched or chipped.

Scratches Or Cracks From Furniture

Another common cause of wear and tear on a concrete floor is from the furniture. If you have heavy furniture that is constantly being moved around, it can cause scratches or cracks in the surface of your concrete.

Sun Damage

The sun can also be a significant factor in the wear and tear of a concrete floor. If your floor is constantly exposed to the sun, it can become faded and discolored.

How To Prepare For The Project

Assess The Damage

The first step is to assess the damage. Take a look at the floor’s surface and identify any areas that are cracked, stained, have deep holes, or are otherwise damaged. Once you’ve identified the trouble spots, you can begin to plan your restoration strategy.

Minor Damages

If the damage is minor, you may be able to fix it with a concrete patch. This is a quick and easy way to fix small cracks or holes in your floor. Mix the patching material according to the instructions, and use a putty knife to apply it to the damaged area. Allow the patch to dry completely before walking on it.

Major Damages

If the damage is more extensive, you may need to do a complete resurfacing of the concrete floor. This process involves removing the old surface of the concrete and replacing it with fresh concrete. It’s more involved than repairing minor damages, but it will leave your floor looking new.

Clean The Surface

First, you need to clean and dry the existing concrete surface thoroughly. This is a crucial step because it will prevent any dirt, stains, or dust from being trapped in your sealant. You can use a pressure washer and some soapy water to ensure that all the dirt, grime, and dust are off your floor. Once dry, use an edger to remove any loose and raised edges.

You can do this by using a broom or a vacuum cleaner. Be sure to pay special attention to any stained areas or areas that have a lot of dirt build-up.

Repair Any Cracks Or Chips

If your concrete floor has any cracks or chips, you will need to repair them before you can apply sealant. This can be done by using a concrete patching compound. Be sure to follow the instructions on the package so that the repairs are done correctly.

Plastic Sheeting 

You will also need to cover any areas you don’t want sealant on. This includes baseboards, walls, and other surfaces adjacent to your concrete floor. Use plastic sheeting or painter’s tape to protect these areas from overspray.


Next, you should apply a coat of primer where you want the sealant to be used.

After this, using two buckets of water, mix one bucket with a bottle of sealant and one bucket with a gallon of sealant.

How To Seal A Worn-Out Concrete Floor

If your concrete floor has cracks and is deteriorating, you may think it’s time to replace it. However, you can take a few simple steps to get your old concrete looking new again. A sealant will give your worn-out concrete a brand new shine.

Many DIY projects will help you revitalize your old concrete and make it look new again. Once the surface is dry enough to walk on without slipping, layer on an even coat of sealant. Apply at least one more coat of sealant if necessary until the sealant reaches all surfaces of the floor.

Let this dry for 24 hours before walking on it or using it for any other purpose. Next, use a tack cloth to remove any extra dust from the floor’s surface, followed by another application of sealant if necessary to fill any cracks or crevices on the surface. Using a steel trowel and a stiff brush are ideal tools.

Once you complete these steps correctly, you will have no problem rescuing that worn-out concrete floor!

Choosing The Correct Type Of Concrete For Resurfacing

If you decide to resurface your floor, choose the right type of concrete. There are several different types of concrete, and each has its advantages and disadvantages. Be sure to consult with a professional before making your final decision.

Pouring New Concrete

If you decide to go with a full resurfacing, you will need to pour new concrete. This is a more involved process than patching, but it will leave your floor looking new.

Applying A Sealant

Once you have repaired any damage and cleaned the surface, you can apply a sealant. This will protect your floor from future damage and keep it looking clean and shiny. There are several different types of sealants available, so be sure to choose the one that is best suited for your needs.

Removing Old Concrete

If you decide to remove the old concrete surface, you will need to use a jackhammer or other heavy-duty equipment. This is a difficult and messy process, so be sure to hire a professional if you decide to go this route.

Installing New Concrete

If you install new concrete, you will need to pour it into the space where the old concrete was removed. Be sure to follow the instructions provided by the concrete manufacturer so that the new concrete is installed correctly.

DIY Or Hire Someone To Do It For You

There are two ways to repair your old concrete floor. You can do it yourself with a guide, or you can hire someone experienced in the field. Professionals use safety gear like hearing protection and follow the manufacturer’s directions of their products.

Hiring a professional is always the best option, but if you’re up for the challenge, doing it yourself can save you money.

The first thing you want to do is get all of the old sealant removed from your floor and clean the surface.

You will need to use a scraper, sander, or other power tools to remove all of the sealant and any debris. Once everything on top is gone, you will need to vacuum up any dust and dirt that has been created by this process and then sweep up any remaining debris on the floor.

Once this has been completed, it’s time for the fun part! You will want to apply one coat of concrete sealant over your entire surface.

Make sure that your sealant covers every inch of your floor so that when it dries, there are no spots missed or patches too thin (which could lead to peeling).

If you want an even better finish, you can apply another coat after 24 hours have passed, but do not wait more than 72 hours in between coats. Your concrete should look new again in just 2-3 days!

The Bottom Line

Repairing a concrete floor can be a daunting task, but it is doable if you have the right tools and instructions. Follow the steps provided in this guide, and you will be able to rescue that worn-out concrete floor in no time!
