How to Seal a Concrete Floor? 


A sealed floor can be more resistant to oil, water, grease, and other dirt and stains that may damage the concrete since it is porous. It would also become more attractive and neater if it is neat. All you need to do is to ensure that the application process is done properly.  


  • Clean the floor – cleaning the floor removing everything on its surfaces such as appliances, furniture, and other materials. It also involves cleaning the dirt, stains, and debris that can be found on the concrete. Once cleaned, you can now use the concrete cleaner for the application of the new sealer. Rinse the cleaner off and let the floor dry. Caulk and wait for it to get dry.  


  • Remove the old sealer – pour water on the concrete and let the floor dry in a complete cycle of 24 hours before the whole process begins. 


  • Open up the concrete by using etching solution – there are four types of sealers: epoxy sealers, acrylic sealers, silane/siloxane sealers, and polyurethane sealers. Identify the one that you need and get ready for applying.  


  • Apply the first thin layer of sealer through a sprayer – read the instructions provided about the appropriate humidity and temperature and other recommendations. Divide the room for smaller parts for easy application and start with the least accessible sections to the most accessible ones.  


  • Apply the second layer in the opposite direction – use a small paintbrush for sealing the edges of the floor. Ensure a nice stroke every time. When it comes to the other parts of the floor, you can use a rolling brush or paint pad. Apply first the first thin coating in perfect strokes as possible. Make sure to spread evenly the coating. Let it dry. After the first coating has dried, apply the second coating for better coverage and smoother appearance.  


  • Leave it to sit and dry – you need to be ready to wait for a couple of days for it do dry completely. Or at least, follow the instructions provided on the label before you can walk and use your floor once again.
