And if the concrete floor has stain applied, it is important that you also seal the floor so as to preserve its color. You can use a sealer that has either a gloss or matte sheen.

This article will provide you with the steps on how to seal concrete floor. The process is easy, for as long as you follow each of the steps provided on this article.
Prepare the Things You Will Need
Just like with any kind of DIY home improvement project, it is always a good idea to prepare the things that you will need ahead of time. So for these steps, the things that you will need are the following:

  • Broom
  • Bucket
  • Concrete sealer
  • Degreaser
  • Dustpan
  • Hammer
  • Mop
  • Nails
  • Paint brush
  • Painting tray
  • Pry bar
  • Putty knife
  • Quick-dry concrete filler
  • Roller with extension pole
  • Wire brush

As you can see, the things that you will need for the project are basic carpentry tools which you probably have already. If you lack any of these tools, you can simply purchase them at any home improvement store near you.
Take Off Everything on the Surface
First of all, you need to remove all the things that are on the surface of the floor that you wish to seal. Remember this is not a kind of project where you can segment the area when working. After you have prepared the surface for working, you need to pry the molding or the baseboards off the walls with the help of a putty knife or a pry bar. Insert the knife or the pry bar gently and then pull it slowly so you will not end up cracking or breaking any of the moldings or baseboards.
Sweep the Debris
Next, you need to sweep the debris off the floor. Dust, dirt, debris, nails, dead bugs as well as other materials must be completely taken off in order to prepare the concrete flooring to be sealed. Afterwards, open the doors and windows in the room so your working area will be ventilated properly.
Degrease the Floor
Degrease the concrete flooring with the use a degreasing product. This product helps in lifting the oils which have soaked right within the concrete as time goes by. All you will do is to mix the solution based on the instructions stated on the packaged. In most cases, the instruction will ask you to dilute it in a bucket of water and then spread it right towards the concrete flooring with the use of a mop or a brush.
The next thing that you will do is to scrub any specific oily area with a wire brush in order to make the excess oil to emerge from the concrete floor. Afterwards, rinse the concrete surface off by mopping and making sure that you use clean water with mop. Squeeze the mop repeatedly until such time that the degreasing product or any debris and dirt will be removed.

On the next step, you have to let the entire area to dry off completely. The process could take up to 24 hours to be completed. You might want to make the process faster by placing dehumidifiers as well as fans that will blow towards the concrete surface.
Fill the Cracks
The next thing that you will do is to fill the crevices or cracks with the quick drying concrete filler. This can help to ensure that you will be able to create a completely leveled surface right before you start sealing. You can simply pour the filler towards the cracks and then smooth it out with the use of a putty knife. After that, leave the concrete filler to dry for several hours, or as directed on the packaging of the filler. Then pour a small amount of the sealer towards a painting tray. You should now be ready to apply the sealer.
Applying the Concrete Sealer
With the use of a paint brush, seal the edges of the room and grab a paint roller that comes with an extension pole. Use this to apply the sealer on the rest of the concrete floors. Work from one corner of the room and then towards the exit so you will not end up boxing yourself in.
Give the sealer ample time to dry up, which would usually take 12 up to 24 hours. And again, the process can be made easier with the help of some fans and humidifiers.
The next thing to do is to nail the molding as well as the baseboards back to the base of the wall and then return all of the furniture, appliances and furnishings of the room. And you are now done.
Additional Tips
There are some additional tips that you should know to make the process of sealing the concrete floor even easier. First of all, make sure that you repeat the process of sealing the concrete every five years for optimal longevity of the floor. Depending on how greasy the surface is, you might want to repeat the process of degreasing several times right before you finally seal the concrete floor.
If you will choose to stain the surface with a colored or decorative pattern like acid wash, then make sure that you do it right after the cracks have been filled out. This can help to add extra time to the process since the stain or acid should be applied and be left to dry afterwards.
There is also an important warning that you should keep in mind and that is to wear proper gears and safety accessories when working. First of all, you should wear a pair of rubber gloves to keep your hands protected. Furthermore, you should wear a long shirt and long pants so as to keep your body fully protected. Wearing an eye protection is highly recommended as well. Remember that the degreaser as well as the sealer contains harsh ingredients that might irritate your skin and eyes.
