What You Are Going To Need

  • Mop
  • Broom
  • Scrub brush (optional)
  • Kitty litter (optional)
  • Dishwashing soap
  • Pressure washer (optional)
  • Push broom (optional)
  • Sand mix or concrete patch to fix cracks and pits
  • Metal or wood strip
  • Duct tape
  • Self-levelling primer
  • Self-levelling concrete
  • Mixing bucket

Step 1 – Preparing The Surface

You first want to start by preparing the surface that you are going to be leveling. Sweep the floor, so that you remove all the general dust and debris. If there is any fine dust or dirt left behind, you want to utilize a mop.

You can even go as far to scrub the area with a push broom and mild cleaner like dishwashing soap. If there are oil or other stubborn stains on the surface, you might have to scrub the area with bleach.

Grease is usually best removed with the utilization of kitty litter, but it will take a few days for the material to soak up the grease.

Some individuals will even utilize a pressure washer, if the floor is extremely dirty and caked with stains. Whatever method you choose doesn’t matter as long as it gets the job done, and you wait until the surface is completely clean and dry before moving on.


Step 2 – Filling In Pits And Holes

If there are any pits, holes, or cracks in the concrete, it will be easier in the long run to go ahead and fill them in right now. You can do this by utilizing a sand mix concrete or concrete patch.

Just follow the manufacturers directions on the back of the product for the best results. Make sure your let the repairs dry and harden before moving on.


Step 3 – Sealing Off Doorways And Openings

Now, you need to seal off any doorways or openings. You can do this by using a strip of wood or metal. This prevents the concrete from spilling out of the desired area.

Just make sure that you use a strip of metal or wood that is taller than the height of your new concrete. You can also even use duct tape to secure the wood or metal strip in place.


Step 4 – Self-Leveling Primer

To help the new concrete resurface material adhere better to your existing floor, you should use a self-leveling primer. Just simply brush it over the entire area.

You will probably have to apply two coats, and it can take anywhere from one to two hours for each coat to dry. Make sure you let the surface completely dry before moving forward.


Step 5 – Applying The Self-Leveling Concrete

You are now ready to apply the self-levelling concrete. Start by mixing the concrete in a large mixing bucket, while occasionally adding water. Once you have the right consistency you want to start at one end of the room and simply just pour the concrete out until you have covered the entire area.
