How to Coat Your Garage Floor to Update the Look

27 Comments

Painting the garage floor is a great way to update and protect it. This DIY project for concrete floor coating has been durable and made a huge difference! 

I partnered with Behr Premium Granite Grip to update our garage floor and write about our experience.

How To Paint Concrete

We are sprinting down the finish line in the garage makeover! The last time I updated you, we had a major project in mudding and painting the garage walls. Now that the walls are done, I am very excited to be moving on to more…paint?!  Well, sort of, but this one is worthy of excitement. We are painting the garage floors!

You see, 3 years of DIY had left our garage floors looking a little worse for wear…

Garage-floor-before

Several months ago, hubby had asked me to find a garage floor coating product to turn our nightmare floor into a respectable shop to work in. This space is the center of our DIY world. It’s a garage filled with hopes, creativity, and a whole ‘lotta sawdust. We needed a product that was beautiful but wouldn’t reflect the sun in our eyes while working on the table-saw. After months of searching for a product that would hit all of our criteria, I found this:

Behr Granite Grip with Finished Floor

We chose BEHR Premium Granite Grip for a few reasons:

  • Non-slip coating
  • Not reflective or glossy
  • No 2-step insane epoxy (this is much easier!)
  • Durability – We can drive on it and it resists against dirt, grease & household stains

If you are planning on recoating the garage floor, there are a few tips to make your project the best it can be. Prepping may look like a lot of work, but, truthfully, we did all of the prep work (except moving stuff) in a single day. For additional instruction and examples, check out this  how-to video from Behr.

Materials Needed for Painting the Garage Floor

How to Prep the Garage Floor for Painting

Moisture Test

The absolute first thing to do is a moisture test. If your concrete floor collects moisture, it can get under the coating and you will not have a proper bond. The good news is that it is pretty easy to test. Tear off a few feet of clear plastic wrap and lay it on the floor. Use Duck Tape or another well sealing tape around all of the edges. I would recommend leaving for a day or two and check periodically if any moisture, color change, or condensation collects on the floor or the underside of the plastic wrap.

Move Everything off the Floor

Finding a place to store everything from the garage might just be the biggest hurdle. This whole process will take a few days so I recommend doing it all at once. Our bench is built into the wall, so we left that.Etching Concrete in garage with personal protection muriatic acid

Clean and Degrease the Garage Floor

Make sure you scrub off any oil, dirt, or chippy paint from the floor. This is crucial for a proper bond. Use a good degreaser and a long handled scrub brush to remove any contaminants.

Acid Etching the Concrete Garage Floor

Next is the etching. Acid etching is the best way to prep concrete to accept and bond with the coating. While etching isn’t hard, safety is the priority here. Muriatic Acid, also known as hydrochloric acid, is a strong acid. It is inexpensive but can do some damage so wear safety goggles, rubber gloves, and old shoes you don’t care about. Hubby is sensitive to fumes so he wore a respirator mask. That was probably a bit of overkill, but we are overkill kind of people. Don’t be scared, just be safe!

Read and follow all manufacturer’s instructions for the muriatic acid and use only with adequate ventilation . You may have to do a few applications depending on the density and smoothness of your concrete.

Tip: Always pour acid into water, NOT water into acid. Does anyone else remember those “What Not to Do in the Chemistry Lab” videos from school? The boiling acid example makes this rule pretty clear.

 Neutralize and Rinse

Neutralization of the acid was important to us because we were rinsing down the driveway. Mix 1 cup of baking soda to 1 gallon of water and sprinkle over the floor.  Allow to sit 10 minutes and then rinse with a garden hose.  When mostly dry, wipe your hand across the floor to make sure there is no powdery white residue left behind. If there is, thoroughly rinse again. Allow the floor to dry completely (2 days).

Tip: The concrete should be approximately the roughness of 150 grit sandpaper. If not, repeat the etching process.

Using Behr Granite Grip Ornamental GemSteps to Recoating A Garage Floor

Now that everything is prepped, your garage floor is ready for coating. Granite Grip covers 50 sq. ft per gallon. For our two car garage, we used 8 gallons of Ornamental Gem, but there are many natural-looking color options. Make sure to regularly stir the aggregate/flakes suspended in the paint solution. Cover small cracks first with a brush and let dry before your next coat.

There are two ways to apply Behr Premium Granite Grip. The first is renting a texture sprayer from any Home Depot that has a tool rental department and I highly recommend this option. Application is easier, faster, and you will be sure there are no roller marks. If that isn’t a possibility, you can use an adhesive roller (not a regular paint nap roller) to apply Granite Grip. Working in a 4×4 area, make sure to minimize roller marks by working in a random pattern.

Tip: Both the acid etching and the Granite Grip must be applied when air/surface temperatures are above 50 degrees F.

You need to apply at least two coats to get full, even coverage. Wait at least 4 hours between coats. We actually applied 3, but our coats were thin and we still kept within the 50 sq ft per gallon recommendation from Behr.

The floor is ready for light traffic in 24 hours but allow coating to dry for 72 hours before subjecting to automotive tires. Longer dry time required in cooler temperatures and in higher humidity. Don’t rinse the floor for 30 days and you have yourself a great floor!

Here it is, completed and pretty! I definitely made the right choice for our floors and hubby is happy which is the most important thing.  Now that everything is back where it belongs, it’s back to work for us on our next DIY project.  With spring in the air, it is time to start some of those long overdue outdoor projects.

But the real question is, are you ready to create your very own garage retreat?!

*Update: It has been 6 months since we coated the garage floor, and I can say that I am very, very happy with it. We have NOT been gentle at all and spills are easier to clean up and it looks just as good as new…when the floor isn’t covered in sawdust, haha.

  1. Firstly, thank you for the details on how to do this. I feel I read the comments but I may have missed this response. I am wondering what advice you have if the garage floor is already (poorly) painted. Can I simply paint over it if all other factors are properly in place?

    • For a surface like you are talking about, you should make sure to remove any loose or chipped paint. Presence of moisture and/or sealers will prevent the coating from adhering properly and may cause product failure. To test paint bonding, you can follow these steps:
      1. With a razor blade, cut an X through the coating and down to the concrete.
      2. Apply a 4” piece of duct tape over the X and press firmly.
      3. Completely remove the tape with one quick pull.
      4. If less than 25% of the taped area is removed, the existing coating is adhering well and you may apply the over the existing paint.Thoroughly clean the surface to remove any dirt or contaminants. Prior to applying the Granite Grip, the previous coating will either need to be scuff sanded with coarse sandpaper.
      5. If more than 25% of the taped area is removed with the tape, the original coating is not adhering well, and the floor should not be coated unless all previous paint is removed using a concrete floor sander or suitable paint stripper.
      Hope that helps and good luck with your project!

  2. Excellent article – it’s now 18 months later. Can we see a picture and a brief update on how it’s holding up?

    For any one else who has used this to re-do their garage and parked their cars on it, how is the coating holding up?

    Thanks

    • We are in the middle of a few furniture building projects in the garage, so photos would be hard. However, I am super happy with the durability and longevity of the granite grip. We have driven, dragged, dropped stuff, and generally been pretty harsh on the floor. (It’s the DIY Life!) However, it hasn’t stained or discolored no matter low long between cleanings. No flaking, chipping, or scuff marks either. I need to touch up a few areas because my 9 year old son dragged a trash-bag full of white paint supplies across the floor and left paint marks, but nothing would have helped that. Honestly, I am really impressed and I would be honest if it wasn’t.

  3. Hi! I’m wondering how this would do on a pool house floor. We are looking for a waterproof coating but it must be nonslip as well. Any ideas? You

    Reply

    • I have heard that this is perfect for a pool area application, so long as it is allowed to dry properly and passes the moisture test I described in prepping. For maximum success on outdoor applications, I would pick a time when rain isn’t likely to happen for at least several days, and use a sprayer rather than a roller if it’s a large area just because it’s faster to lay down. Many Home Depot stores have them available for rent. It is definitely non-slip, which I love, but it isn’t as rough as concrete applications you see at community pools.

  4. Hi
    I live in Ohio and during the winter salt is transferred on to the garage floor from the tires. Will the salt damage this coating?
    Thanks for the post.

    Reply

    • Salt would be abrasive, but I don’t think chemically it would do any damage. We have thrown just about everything at this coating and it looks just as good today as it did when it was new, except where my son spilled some white paint. That we will have to touch up.

  6. I applied the granite grip coating to My heated garage about 6 weeks ago and it cured very quickly due to having a heat pump. Do you know What should I use to clean the floor when necessary? I am going to be using it for a dog kennel area and will need to be able to clean the floor periodically. I have searched the Internet and cannot find a recommended cleaner. I normally use a non-toxic, bleach free kennel cleaner that kills bacteria and any animal viruses. Do you think a product like that would be safe? I don’t want to compromise the integrity of the coding so that the flooring will last many years. Any suggestion from anyone would be greatly appreciated. Thank you-Kim

    • I have honestly been cleaning ours with water and a decent scrub brush. We use simple green to clean up things like grease if necessary. A kennel cleaner probably has a neutralizing agent in it, so it should be fine.

    • Hey, Kim, Kim here. How’s your kennel floor holding up ? I found this while searching for an easy to clean , no skid but not too rough flooring option.

  7. hi I’m wondering if you know if we can cover Granite grip with an epoxy or other clear finish to smooth the surface a little bit. I love the look and the depth and would really like to give it a Sheen or glossy look. I just want to make sure the product I use is the correct one.

    Reply

    • That is a great question! I’m sure that it would be fine actually as long as you waited a few days to put the second coating on. I would check with either Behr directly (try their FB page or customer service line maybe?) for a specific product to use.

  8. You emphasize the importance of the moisture test but did I miss the follow-up? If there is moisture are there additional steps or is that the end of the project?

    Reply

    • For this particular paint, I probably wouldn’t recommend it if the moisture test fails. That isn’t to say that there aren’t products out there that would work. I would probably check with Rustoleum or a local paint company like Sherwin Williams if they have something that would work.

  9. Two questions:
    1. If we didn’t have the concrete folks apply a smooth finish, could we skip the step of etching?
    2. Would this also work for patios made of concrete? Is it scratchy to the touch or uncomfortable to sit on. Random but helpful if there are kids sitting on the ground of the patio.
    I’m happy I found your post! I was just asking my husband the other day if it would be crazy to try to epoxy our new garage (we’re building in December) and he said yes. I feel like this is an awesome and affordable option!!!

    • Thank you so much for your questions! With any kind of “paint” or epoxy, proper bonding means increasing the surface area. It’s just like sanding before you paint furniture, if that makes sense. If your concrete floor feels about the equivalent of 150 grit sandpaper or rougher, then I think you would be fine without etching first, as long as you give it a good cleaning and remove any oil, stains, etc. Secondly, an outdoor concrete patio is perfect for this (see my last note). It has a non slip surface, so the closest I can compare it to is like a nonslip bathtub bottom. I walk on it in my bare feet all the time. I feel like it’s much more comfortable than bare concrete! It also doesn’t seem to be as prone to temperature fluctuations. Concrete can be so cold but I notice this coating isn’t as cold. Lastly, my experience is painting a garage floor and I looooooove it! I love that it isn’t shiny or glossy or dangerously slippery when wet like epoxy based coatings can be. But I do think that the considerations are different for something like a non-shaded outdoor patio. Ours has been great, but I have seen a few reviews say that it chipped off their outdoor concrete. That could be user error (i.e. they didn’t do a moisture test and condensation got under the paint), but I like to be thorough. I hope that answers your particular situation and good luck with your project!

    • I can’t personally vouch for tires, since we have only driven a motorcycle on it a few times and parked the bicycles. Ours has held up really well to grease, machine oil, and our son who somehow never makes it to the street with the kitchen trash. The smoker leaves tracks on it when we wheel it around, but those have rinsed off easily. The directions say that it’s made for driving on, so that is all I know. Either way, I would absolutely not drive on it until the floor was fully cured. I wish I could be more definitively helpful! You can probably message Behr through Facebook/twitter or ask a paint expert at Home Depot.

  13. Our garage is in constant use. We have it very well organized but its still more of a workshop with the big power tools than a car garage. I want to reseal the floor like this and from the looks of your example it would be well worth the time and effort. Great makeover.
