If your floor is damaged and it has debris, you need to move the large objects. Use the broom to sweep the entire floor to remove the debris, particles and make the space completely clean. If your floor has cracks, dips or holes, make sure to clean it and remove debris from them too.

You can also use acid cleaner to clean the floor and remove oil, debris, dirt or any residue that was impossible to remove with sweeping. Muriatic acid is one of the best cleaners that are used for cleaning the concrete surface. It can also soften the old concrete surface for bonding procedure. Be careful when using the acid wash as they are dangerous. Use gloves and masks for protection.

After the chemical has done its job, you need to use pressure wash method to clean the concrete of any acid. Make sure to completely clean the concrete surface using high pressure wash method.

  1. Use the Liquid Floor Latex for Bonding

The next thing you need is a bonding product. Applying new concrete to the old one is not easy. You will need a bonding agent to complete the job.

The last feature is what you need when you need for concrete to concrete bonding.

Here is what you need to do:

Take a clean bucket and add cement powder to the liquid latex floor product. Make sure to read the measurements on the container for accuracy. Mix the two things well and make sure that there are no lumps in it. Never try to mix it on the floor. It will never work. Always use a mixing bucket to mix the two things and do it properly. Use gloves and masks to protect yourself from the dust and smell.

The mixture will harden quickly, which means you need to use it as soon as possible. Don’t leave it just like that for too long. Apply the mixture within an hour of mixing.

  1. Applying the Mixture

It is now time to use the bonding mixture to apply the new concrete floor. In order to make the old and new concrete bond together, you need to wet the floor. This will make the old floor read for the application. At the same time, make sure that that you don’t leave any puddles of water on the floor. The process will not work efficiently. All you need to do is wet the floor just enough.

You need to prepare a fresh batch of mixture just with water and cement powder. Use a mixing bucket and mix it well. No lump should be there. After you are done, make sure that you are ready to use the mixtures.

Use a brush and apply a thin layer of mixture on the damp floor. Make sure that the entire area you are trying to fix is covered in thin layer of the bonding mixture.
  • Now pour the concrete mixture you prepared for flooring over the surface that is now primed with the bonding mixture. Pour the entire mixture on the floor and spread it evenly. Use a trowel for best effect. You can use any leveling tool to evenly distribute the mixture on the floor. Make sure that the floor has even layer of the mixture so that it dries evenly without any lumps or waves.

After the application, you need to let the mixture dry completely. Give it hours to dry even if the time is 12 hours or less. Make sure that no one steps on the floor or no object or thing is placed on it. This is very important. After it dries completely, you will see the new concrete surface is beautifully sitting on the top of the old one and provides a very smooth surface.
