How do you bond new concrete to old concrete?
When using a liquid bonding agent, paint the bonder onto the existing concrete and allow it to dry until it is tacky. This usually takes only a few minutes. Then apply the repair material. Just as in the process described above, after the bonder has become tacky apply a scratch coat and then apply the repair material.
How do you seal crumbling concrete?
- Rub the bristles of a stiff scrub brush over the edges of the crumbling area to remove loose concrete and dirt.
- Apply a thin coat of concrete bonding agent over each of the crumbling areas, using a medium to large paintbrush.
- Apply a layer of prepared concrete 3/8 inch thick with a pointed metal trowel.
What causes cement to crumble?
Concrete seems like a stable and permanent material, but it remains porous and will absorb water. When this water trapped inside the concrete freezes, it pushes the cement binder apart. This expansion, and the resulting contraction when the water melts again, causes crumbling.
