Can you stick concrete to concrete?

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. Unfortunately, there are some disadvantages to pouring new concrete over old concrete. A big problem would be that it can reduce 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. However, if the old concrete is not in good condition, it will significantly reduce the life of your floors over time. While it is possible to use old concrete as a base for new concrete, many factors will determine whether the concrete is strong enough to accommodate the new batch. The most common use for bonding cement is to build block walls without mortar joints, but you can also use it to join two other concrete surfaces.

However, if there are unresolved problems with your old concrete, including piles of frost and cracks, they can be moved to new concrete. Joining the new slab to the old slab involves creating a joint that structurally connects the two while providing a flexible point for the two pieces of concrete to respond to weather and other external manipulations. When the surface of a concrete floor is damaged, there is usually the option of demolishing the floor and starting over, or re-paving existing concrete. If it is a deck or slab repair, mixing concrete with an adhesive agent allows you to quickly work and form the repair on the deck.

Use this product as a paint adhesive, covering the surfaces of the base with a sprayer, roller or brush before applying a fresh coat of concrete. Whether you mix the agent with a grout or use an agent to join two concrete surfaces, a high-quality product can do the job. Liquid Nails LN-905 Landscape Block Adhesive creates a weather-resistant bond that resists the effects of water, resulting in a long-lasting concrete wall, garden bed or masonry project. The most effective way to ensure that the adhesive agent enters the existing concrete is to apply it directly with a brush or rag.

For large projects, coarse aggregates have large gravel and are more durable, ensuring that concrete is stronger and more durable. The thinnest layer of new concrete that you should apply to old concrete is about 2 to 2 ½ inches. But if you are building a small part of your yard or just want to try DIY construction, this is the process you need to follow for a solid and reliable bond between old and new concrete. The two pieces of concrete will not make a perfect bond; however, following the instructions correctly and using a suitable bonding agent will make your concrete strong and sufficiently adhered.
