Concrete is a strong and durable material, but it does not have any natural adhesive or bonding agent. This means that when you put concrete on top of another layer of concrete, it will stay there as a separate layer without joining. It will not produce a strong or useful floor. You can add new concrete to an existing concrete slab if the old concrete is in good condition.
To do this, you must thoroughly clean the old concrete surface and use a suitable concrete bonding agent before pouring the new concrete to meet all structural requirements. However, there are some drawbacks to pouring new concrete over old concrete, such as reducing the lifespan of the area. For example, a new concrete building on a new gravel base will ensure that the structure is robust and can last up to 40 years. But if the old concrete is not in good condition, it will significantly reduce the life of your floors over time.
This adhesive agent will be painted over the old concrete to ensure that the new concrete adheres successfully. When new concrete is added over dry old concrete, the two will not be bonded together without a binder. Regardless of which adhesive agent you use or why you are gluing concrete to concrete, the process should always begin with surface preparation. Treating plastic with a mold release agent before it comes into contact with concrete is the best way to ensure that your plastic buckets and tools remain free of dry concrete.

Understanding how to make concrete adhere to other materials is essential when repairing old concrete or pouring new concrete. The reason you're trying to join concrete with concrete will dictate the best method for your project. For instance, when wet concrete is poured onto dry concrete, it dries out, but in reality it does not adhere. The two pieces of concrete will not make a perfect bond; however, following the instructions correctly and using a suitable adhesive agent will make the concrete strong and sufficiently bonded.
To prevent concrete from sticking to these materials, you need to treat them with a mold release agent to prevent the concrete from sticking by forming a thin lubricating film on the material. Whether it's indoor floors or an outdoor deck, surfaces made of concrete suffer wear and tear and often need repairs and maintenance. If you are repairing existing concrete, you will need the material to be attached to these materials in order for the repair to last as long as possible. If you do not want the concrete to stick to wood, you must use a mold release agent for easy removal.
