You can pour concrete on top of an existing slab as long as it's still in reasonably good condition and structurally sound. This means the concrete should be free of cracks, buckling, and breaks. If you notice any small cracks or minor issues, it's in your best interest to repair them before you pour the new concrete.
The best materials to resurface concrete include acrylic overlays, epoxy coatings, cementitious resurfacers, decorative overlays, and polyurethane toppings.
The best materials to overlay concrete are epoxy coatings, micro toppings, self-leveling overlays, stamped concrete overlays, polymer cement overlays, spray-down toppings, and polishable overlays. Each offers unique benefits such as durability, customization options, and ease of application.
Besides being more cost-effective than replacing the slab, you can resurface your concrete in a single day. After cleaning the concrete with a power washer and filling in any large cracks, all you have to do is pour and smooth the resurfacer to hide any surface damage!
Apply A Bonding Agent
This substance acts as a bridge between the old and new concrete, improving the adhesion and overall strength of the bond. There are different types of bonding agents available, but the most common are latex-based or epoxy-based.
Does concrete stick to concrete? If you pour a new layer over concrete right on top of the old one, you won't get proper adhesion. You must properly prepare your concrete slab and then apply a chemical bonding agent on top of it so your new concrete adheres properly.
A concrete slab in direct contact with the ground should be at least 3 ½” thick, but the minimum thickness is only two inches when adding an overlay.
Since cement lacks any natural bonding agents, newly-poured concrete won't naturally bond to the existing slab. You'll need to either use a bonding agent to adhere the two layers together or use an unbonded overlay method. Condition-affected life span: Properly installed concrete can last for over 50 years.
Unibond (SBR) is a modified styrene-butadiene liquid emulsion that works as a ready-to-use bonding agent for repairing spalled concrete floors, columns, beams, and slabs. Its bonding capabilities also work well when bonding old concrete and mortar to new layers of concrete and mortar.
In short, the difference between cement vs concrete is easy to clear once we know all the basics of their compositions. Cement is a binding agent made from limestone and clay; whereas concrete is a building material created through the proper mixing of cement, water, sand, and rock.

This material is typically produced at a utility sluice pond site by dumping raw ash into the pond and allowing it to hydrate and harden into a working platform. Additional raw ash is placed on top of the platform in thin lifts, watered, compacted, and allowed to hydrate and harden.
Fortunately, it is possible to place stamped concrete over existing concrete. Stamped concrete overlays are durable options for upgrading, repairing, and enhancing existing concrete.

The easiest method for applying concrete resurfacer is to pour a small amount on the surface, then immediately begin spreading it evenly with a light, long-handled squeegee. Resurfacer can also be applied with a trowel or brush. Work in segments of no more than about 144 square feet at a time.
How Thick you can pour Self-Levelling Concrete depends on the specific product used. But standard Thicknesses are between 3 mm and 10 mm. However, it is possible to get options that pour as thin as 1mm and as Thick as 120 mm.
