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.
Can you put stamped concrete over existing concrete.
You just have to consider the added height.
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.
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.
You can if the concrete is sound solid with minor cracks pitting scaling surface damage or just plain ugly.
First you pour the new concrete then you press the stamps.
A stamped overlay offers all the aesthetic benefits of conventional stamped concrete but is applied over existing concrete.
With some supplies and a full day of dedicated labor you can transform an otherwise plain surface.
If the new concrete is 3 inches thick or more you don t have to bond the new concrete to the old concrete.
The same principles as above apply to pouring concrete over an existing concrete driveway or sidewalk.
My rule of thumb is this.
Installing a stamped concrete patio over an old surface is a two part process.
Concrete slabs provide strong surfaces that withstand years of wear and tear with little maintenance.
If the existing concrete is structurally sound is not heaving or settling then you can pour concrete over concrete.
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.
