How to Bond New Concrete to Old 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 New Concrete to Old Concrete?

Bonding new concrete to old concrete can be a difficult task, but with the right tools and techniques, it can be done successfully.

The most important thing to consider when bonding new concrete to old is the adhesion or bond strength between the two surfaces.

If the bond is not strong enough, the new concrete will not stick to the old. There are several steps that should be taken to ensure a strong bond between new and old concrete.

The first step is to inspect the old concrete surface. Any cracks, holes, or any other damage should be fixed prior to applying the new concrete. If the old concrete surface is not level, it should be leveled with a cement trowel before continuing.

This will ensure that the new concrete has a smooth surface to adhere to. The next step is to prepare the new concrete for bonding.

The concrete mix should be chosen carefully to ensure that it will adhere to the old concrete. If a readymix concrete is being used, the directions on the bag should be followed closely.

The water to cement ratio should be checked to ensure that it is correct. This will ensure that the new concrete is strong and has the right texture for bonding. Once the new concrete is ready, it should be applied
