DIY tips or sealing a concrete floor

How do you seal a concrete floor?
Concrete flooring is an excellent choice for any home. Especially if you're looking for durability. However, longevity of the floor depends on sealing it correctly being that concrete is porous. Sealing a concrete floor is crucial to avoiding stains from substances such as water, oil, grease and other contaminants. Some other benefits of sealed floors, besides the beauty, is that they are easier to clean.

To make sure that the sealer does its job the application process must be done perfectly. The steps that are done, from surface preparation to using the correct application tool will effect the final outcome.

How to approach sealing a concrete floor
Below is a summary of the steps for sealing a concrete floor


  1. clean the floor (remove dust oil stain Saturn Aura from the surface)
  2. Remove the old sealer from the floor
  3. Utilize an etching solution to “open up” the concrete
  4. Use a sprayer or roller to apply the first coat of sealer
  5. After the first coat has dried apply the second coat in the opposite direction
  6. Do not touch the sealer on the concrete until it is fully dried ( avoid foot traffic or vehicle traffic on the concrete until its dry)

Cleaning the floor
To avoid any inconveniences, you should move all of your furniture or other items out of the room. These items will need to be stored for less than a week. Once the room is cleared you will then thoroughly sweep the floor then make sure to double check if there is any remaining.

It is recommended that you use mineral spirits to cleanse grease spills. After a visual check to make sure that the floor is clean you will then use concrete cleaner to prepare the floor for sealing. The next step is to rinse the cleaner off, and wait for the floor to dry. If you see any visible cracks you can use concrete repair caulk to fill them. Then you must wait for the concrete caulk to completely dry.

Removing the old sealer
If your concrete floor has an old sealant then you must wait before applying the new sealant. If you are unsure whether your floor already has a sealant on it or not, you can use water to test this. You do this by pouring one cup of water on the concrete,  if the water does not soak into the concrete but instead remains on the surface then you will know that the concrete was previously sealed.

If you have determined that there was previously a sealer on the concrete floor and you will use a chemical stripper to remove it. Chemical strippers are acid based so be sure to protect yourself when using it. After using the stripper you will have to let the floor dry for a minimum of 24 hours. 

Using a sealer
There are four types of sealers to choose from:

-Epoxy sealer
Epoxy sealer are more durable than acrylic sealers because it sits on top of the concrete. Epoxy sealer will protect the concrete floor against stains from grease but they are also difficult to apply. There are also a wide variety of colors and looks you can choose from with this type of sealant.

-Acrylic sealers
T
his sealer is typically used for interior floors and are very easy to apply but they do not effectively protect the floor from Grease or oil stains.

-Polyurethane sealers
This type of sealant is mainly used over other types of sealers. Polyurethane sealant offers UV protection which will prevent the concrete from turning yellow over time. This is usually applied in a thin layer that sits on top of the concrete

-Silane sealers
You can utilize this type of sealant if you do not want to change the look of your concrete floor. Since this sealer penetrates the concrete, it will not change the gloss or tone of the concrete. The floor will remain that matte gray color we have come to know. Silane sealers are known to last 20 years or more and will protect the floor from deterioration and staining.

Applying the sealant 
  1. Make sure to go over and understand the instructions for each particular sealant. The manufacturer's instructions will ensure that you get the results that you are looking for.
  2.  When applying a concrete sealant make sure to ventilate the room. This can be done by using an outdoor facing fan to create airflow leading out of the room. 
  3.  If you are using an epoxy sealant next the two parts together. You will pour the contents of the smaller container into the larger container and uses stick to mix them together.
  4.  While applying the sealant of your choice you should divide the room into smaller sections. This means starting in the back corner or the least accessible area and work your way back towards the door.
  5.  You can utilize a small paint brush you make sure that the sealant reaches to the very edge of the room where a rolling brush may not reach. You will want to use even strokes while applying the sealant.
  6. When you go to apply the second coat it should be thinner than the first coat,  this will give you a smooth and even finish.  let the sealer dry based on the recommended manufacturer instructions

Sealing your concrete floors is the perfect way to increase the lifespan of the floor while also increasing its beauty. The best part is that you can easily seal your floor as a DIY project but it's this is something out of your realm then you should hire an expert!
