You can add new concrete to an existing concrete slab if the old concrete is in good condition. You will need to thoroughly clean the old concrete surface and use a suitable concrete bonding agent before pouring the new concrete to meet all structural requirements. In order for concrete materials to bond effectively to each other, you must apply an adhesive bonding agent. A bonding agent (bonding adhesive) must first be painted over the existing concrete to ensure that the fresh concrete adheres properly.
If there are spills that have seeped into the floor surface, grinding or milling may be necessary to remove the upper few millimeters of the existing floor surface in order to clean the concrete. However, unresolved issues with old concrete, such as cracks or frost, will carry over to new concrete if left unresolved. In each of these situations, you must remove old concrete, resolve the existing problem, such as removing tree roots, and continuing with new concrete. When you want to consider the exact thickness of your new concrete, it's best to look at the surrounding environment where the concrete should be.
The concrete should be approximately 2 inches thick and quickly ensure that the new concrete is level and smooth before using the seals. If too much water is lost in old concrete, there will not be enough water to hydrate all the cement particles and the result will be a lower strength material. Then, if you want to patch the concrete, apply a thin layer of cement paint, pour a well-mixed concrete patch into the holes and clean the surface with a wooden float.

You may need to ask some helpers for help with the process of laying the new concrete and stamping it. As seen above, concrete will not adhere to another concrete material if an effective concrete adhesive is not applied. As I mentioned before, anything like a door or a staircase would justify getting rid of old concrete and starting from scratch.
