Bonding agent for the cementitious substrate

AVCRETE - BONDING ADDITIVE is used for bonding old to the new cementitious substrate

The cement which is part of the concrete mix does not have any natural bonding agents. In certain scenarios, when fresh concrete is added over an existing or old concrete layer, they exist as two separate layers without any bond. Once cured, the new concrete will simply sit on top as a separate layer. This will not produce a strong, serviceable floor. To avoid these, concrete bonding agents are used. A bonding agent needs to be applied onto the existing concrete first to ensure that the fresh concrete will successfully adhere. Whether mixing the agent with a slurry or using an agent to bond two concrete surfaces together, a high-quality product can get the job done. It is applied over the existing surface of the concrete so that the new layer of fresh concrete successfully adheres to the old layer. The bonding agents should be carefully and thoroughly applied, either with a brush, a broom or a roller – or for larger areas they can be sprayed on.

What are the advantages of a bonding agent? 

  • Easy to use and apply.
  • Reduce shrinkage cracks
  • Reduces permeability of concrete 
  • Improves adhesion between the layers of concrete
  • Tensile, flexural and bond strength of the concrete or mortar are increased
