Applying A Garage Floor Sealer

Adding a garage floor sealer can make your garage look a lot better and it protects the floor from the normal wear and tear associated with driving a car in and out every day along with all the associated big boy toys found in a normal garage. The idea behind the sealant is to protect the floor but you can also add tinting and color chips in order to make a great fashion statement. Any car will look better sitting on top of a shiny, colored floor and garage floor sealers can offer you a very dramatic look.

You can find floor sealer kits at any hardware store and home improvement store such as Loew’s or Home Depot. The kit contains the epoxy resin and hardener and you can also have it tinted or buy coloring to add. A standard kit does the floor area equal to a single car garage so if you have a bigger garage than that you will need to buy more than one kit.

The first step, as in any project, is to make sure your surface is prepared for the application of the garage floor coating. You can start by sweeping out the entire garage and then removing anything that is stuck to the floor such as gum, silicone, or other sticky things. You will be much happier with your results if you treat the entire floor and not just where the car sits. I recommend removing everything from the sides and corners of the garage so you can get a full coating. You may need to do one side one weekend and then move everything to that side and do the other the next. You will be a lot happier with the results.

Once the floor is swept, everything is scraped up, and all you treasures are moved out of the way it is time to start cleaning. At this stage it is good to use a fine quality degreaser to remove any grease and grime that has accumulated. If there is any oil or grease stains on the floor then a concrete garage floor sealer will not bond well and you will have bubbling and lift of the epoxy. Use the water bead test to determine if there is any petroleum substances left after degreasing. Spray the floor with water and see if there is any beading. If the water beads this indicates you still have more cleaning to do. If it passes the bead test then use soap and water to get all the degreaser off.

The next step is to etch the floor so the epoxy garage floor sealer will adhere. You can use a commercial etchant for this or just use a 10% muriatic acid solution mixed with water. This roughs up the surface so the epoxy will bond. It also breaks down and removes any coating that the concrete contractors may have applied in order to get a shiny look on the floor.

After rinsing of the acid solution with water allow the floor to dry for 24 hours. When you are using garage floor sealers you don’t want to do it in the dead of winter unless you live in the sunbelt or south. The minimum temperature is about 50 deg. F for apply epoxy products if you want then to cure properly. Also, the temperature should not be over about 95 deg. Also, the epoxy will have a lot of vapor so you will want to have good ventilation. Be careful about dust though as this will stick to the epoxy and change the color and surface characteristics.

Once the floor is dry and prepared start rolling out the mixture in a back corner. Start here for two reasons. First, if you mess up it will be easier to hide and second, you don’t want to paint yourself into a corner. Start with the furthest area away from the door and work your way out. It is a good idea to not mix too much up at once because it will often times start curing within about 10 minutes. Also, if you make a few batches it is easier to see how your coverage is going. You don’t want it real thick at the beginning so your run out before you are done and you don’t want it real thick at the end because it really doesn’t give as good a result. I recommend purchasing one extra kit which you can set aside in case you run low. It is much better to mix some more up quickly and keep going than it is to have to stop and run back to the store. If you don’t use the extra kit then you can return it for a refund.

While you are rolling out the epoxy you will want to apply any color chips and anti-slip materials you plan to add. It works best to cover an area with the epoxy then spread the covering, then roll out another section and spread. Keep doing small areas at a time so you can give a uniform look.

You can usually walk on the floor within a day and drive on it within three to seven days. Don’t try to put your car on it too early as you want to have a good cure for optimum toughness. Also, putting hot tires on epoxy too early can lead to tire lift.

If you want to really make your garage look great, and increase the value of your home, then apply an epoxy garage floor sealer.
