How To Adhere Concrete To Concrete
What is Concrete?
Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material.
How To Adhere Concrete To Concrete
- Loosen Old Concrete. Before you even begin to think about pouring a new layer of concrete over the top, you have to start preparing the existing layer.
- Dust the Surface.
- Mix the Bonding Agent.
- Apply the Bonding Agent.
- Apply the New Cement.
Frequently Asked Questions
What is the best adhesive for concrete to concrete?
Adiseal has been shown to be the top choice adhesive for heavy duty concrete bonding applications.
How do you attach concrete to existing concrete?
Apply the bonding adhesive or interlay layer: Spray the existing concrete with water to dampen the surface. For a bonded overlay, apply a bonding agent. For an unbonded overlay, add your interlay layer so the top surface is level. Pour the concrete and apply the curing compound: Pour your concrete.
What do you use to stick concrete together?
Concrete glue comes in a variety of containers for easy use. For small jobs and home fixes, a squeezable container can be used to apply the glue where needed. For bigger, more advanced jobs, you might need a caulk gun. Construction glue for concrete may be polyurethane-based or epoxy based.
What is the best way to bond two pieces of concrete together?
- Apply the two-part concrete epoxy. Apply the epoxy glue or putty to one or both surfaces, as per the instructions, and remove any excess epoxy glue as quickly as you can.
- Leave it to dry. Support or clamp the bonded surfaces together and leave them to dry for the time specified on the product’s instructions.
What is the bonding agent in concrete on concrete?
Concrete bonding agents are natural or synthetic materials used to join the old and new concrete surfaces. This agent can also be used to join the successive concrete layers. This chemical helps to allow different concrete surfaces to behave like a single unit.

What is the strongest epoxy for concrete?
Why stock multiple adhesives when ULTRABOND® HS-1CC is the strongest doweling and anchoring epoxy for both commercial construction and transportation projects.
What is the concrete bonding agent for old and new concrete?
Epoxy resins are widely used in the construction field because of their high compressive strength, strong adhesion, chemical resistance and other unique properties. They are available for the bonding of fresh concrete to the old concrete. Additionally, they are also used for the bonding of concrete to steel.
Will concrete adhere to concrete?
Concrete does not adhere to: Concrete – Dried concrete doesn’t have any natural bonding agents, so in order to get wet concrete to bond to existing concrete, a bonding agent will need to be used. Molds – Most concrete molds are made from urethane rubbers, which are designed to be resistant to concrete bonding.
How to make concrete stronger?
You can add more Portland cement to bagged concrete to make it stronger. You can also add some hydrated lime. To make the strongest concrete, the sand should be sourced from volcanic lava that has a high silica content.
