Many people working in the construction industry have used sprayed concrete before. Instead of laying out the material as we normally would, we spray it onto the surface. We do so to meet the increasingly complex and ambitious requirements of our clients. The aim is to get the best possible finish.
There are two specific types of concrete spraying. These are the dry and wet spray processes. People often have many questions relating to the two. One of the most commonly asked is whether you need a bonding agent. Allow us to answer this for you in detail.
The wet process
For most concrete repairs, it’s recommended to have bonding agents for the wet process. They’re useful for hand applications too. Yet, the newest generation of repair mortars don’t always demand them. This is if you’ve prepared the substrate well.
In specific situations, it’s wise to have these agents. This is so you can expand the contact section at the interface between the repair mortar and parent concrete. You can enhance the initial tack in addition to the final bond strength.
Dry spray process
For this process you don’t usually need a bonding agent. The reason why is that a percentage of the coarse particles rebound during the first spray stage. This creates a transition layer that’s augmented with fines and cement. Afterwards, it can function as a critical bonding agent.
However, bonding agents are useful for dry spray mortars when you’re working with incredibly absorbent substrates. The agents can stop suction from dragging out the mix water. The repair substance requires this for proper cement hydration.
