Concrete is a strong and durable material, but it doesn't stick to itself on its own. To make a successful repair, you need to use a chemical bonding agent, a bonding adhesive, or a mechanical bond. If you're looking to add new concrete to an existing slab, you'll need to clean the old surface and use a suitable concrete bonding agent before pouring the new concrete. For weight-bearing surfaces, such as floors and foundations, the lack of a solid bond can be a problem.
If you're repairing a deck or slab, mixing concrete with a bonding agent will help you work quickly and form the repair on the platform. For smaller projects, such as gluing one block to another block, a polyurethane-based construction adhesive will do the job. To ensure that the concrete materials bond effectively together, you must apply a bonding agent or stickers. This will prevent the new concrete from fully binding to the old concrete, allowing each to contract and expand on its own when the temperature changes.
Start by sweeping away all loose stones and dirt and rinsing the concrete to prepare the surface. If there are unresolved problems with old concrete, including frost and cracks, they can be moved to new concrete. A variety of concrete repair products are available to repair concrete that has started to deteriorate. Whether it's indoor floors or an outdoor concrete deck, concrete surfaces suffer from wear and tear and often need repairs and maintenance.
