Overlaying is simply a matter of laying a concrete topping of only a quarter inch or so over an existing slab and stamping that new surface.
Can you put stamped concrete over existing concrete.
Aesthetically you can end up with the same coloring and texture that mimics the look of brick stone marble or whatever texture you re after on a newly poured thicker slab.
For this to be feasible the contractor needs to pour at least 2 inches thick use smaller aggregate and incorporate reinforcement such as welded wire mesh or fiber mixed into the concrete.
Concrete slabs provide strong surfaces that withstand years of wear and tear with little maintenance.
You just have to consider the added height.
If the existing concrete is structurally sound is not heaving or settling then you can pour concrete over concrete.
If you appreciate the functionality but want to add style to an existing concrete slab you can stamp new concrete overlay over the surface.
If done properly new concrete can often be poured right over an existing slab.
Pouring concrete over an existing concrete driveway or sidewalk.
A stamped overlay offers all the aesthetic benefits of conventional stamped concrete but is applied over existing concrete.
The same principles as above apply to pouring concrete over an existing concrete driveway or sidewalk.
My rule of thumb is this.
Apply a bonding adhesive over the existing patio and a thin coat of bond release agent over the stamps so they don t stick to the concrete.
Stamped concrete overlays allow you to duplicate the beauty and texture of natural stone brick slate wood and other materials without having to replace your concrete.
If the new concrete is 3 inches thick or more you don t have to bond the new concrete to the old concrete.
First you pour the new concrete then you press the stamps.
