How to Bond Concrete to Existing Concrete?

The most effective way to ensure a really good bond is with a scratch coat. This is simply a very wet coat made up by mixing the repair product with water. Mix up a small amount of the repair material to a soupy consistency. You don’t need to measure the water—just turn the stuff into slop.

How to Bond Concrete to Existing Concrete?

Bonding concrete to existing concrete can be a difficult task, but it is not impossible. It can be done successfully with the right preparation and materials.

Knowing how to bond concrete to existing concrete is important for any homeowner who wants to add a new concrete slab, patio, or driveway to their home.

The first step in bonding concrete to existing concrete is to make sure that the existing concrete is clean, dry, and free of any loose debris or dirt.

If there is any dirt or debris on the surface, it should be removed with a wire brush, power washer, or a vacuum cleaner.

Once the existing concrete surface is clean and dry, it is important to rough up the surface with a stiff wire brush or a grinding wheel.

This will help create a better bond between the two surfaces. Next, a bonding agent should be applied to the existing concrete surface.

This is usually an acrylic bonding agent that is applied in a thin layer. Once applied, the bonding agent should be allowed to dry according to the manufacturer‘s instructions.

Once the bonding agent has dried, the new concrete can be applied to the existing concrete surface. Before the concrete is applied, it is important to make sure that the surface is dry and free of any moisture
