If the self-leveling compound is poured onto a concrete surface that has not been properly prepared, it will not be able to fully bond to it, and will instead cure as a layer separate from the slab, which will be prone to chipping away from the surface or crumbling.
Possible. self leveling concrete can smooth existing hard floors or give a level first layer to put in new inside deck on top of. If you have a compressed wood sub floor, in the same way as other structures do, you can leave it set up and apply self leveling concrete straightforwardly on top of it.
Almost all self-leveling products recommend the use of primers to work as a bonding agent.
Epoxy bonding agents are one of the best options out there. They are known and highly rated for their strength and excellent performance. Epoxy bonding agents are not just for bonding old concrete to new, they can be used to help bond concrete to steel.
Using self-leveling concrete outdoors is usually not a good idea. The natural expansion and contraction of the concrete due to freeze-thaw cycles and moisture absorption can cause the self-leveling concrete to crack or crumble away.

Overwatering the Mixture: Self-leveling compound needs to be mixed with water to create a smooth consistency. However, adding too much water to the mixture can cause the compound to be too runny, resulting in a thin layer that won't level properly.
You need to (1) degrease the concrete, (2) acid wash, (3) rinse and neutralise, (4) apply a bonding agent, (5) then apply the new concrete / mortar / render. Skip any of those steps and your project will fail. Bonding agents can be as simple as water + portland cement powder. No adhesive required.
For smaller concrete gluing projects in and around the house, Loctite Extreme Glue Gel is the top choice. Its highly versatile formula contains Flextec technology which bonds quickly and allows for flexibility.
Quikrete 1 Qt. Concrete Bonding Adhesive permanently bonds existing concrete, plaster and stucco to new concrete, plaster and stucco.
Skipping primer for self leveling can lead to poor adhesion between the self-leveling compound and the substrate.
Due to the nature of the concrete, it can experience problems due to the freeze-thaw cycle or exposure to excess moisture. The extremes that are experienced outdoors can cause self-leveling concrete to crack easily and even crumble.
Self-leveler is also not suitable in areas where heavy machinery is operating or harsh chemicals can impact. Finally, despite its impressive durability, self-leveling concrete is not as strong as traditional concrete and cannot withstand particularly extreme conditions.
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.
Beyond priming, most self-leveling underlayments require that the substrate is free from any contaminants that may inhibit bond, including adhesive residue, sealers/curing compounds, oil, grease, loose or peeling paint, or other contaminants.
Self-leveling concrete is the best solution for repairing concrete floors. This concrete is excellent for concrete floors that have cracks, are sunken, or are uneven. It is a great way to level unleveled surfaces while giving old concrete floors a fresh look.
QUIKRETE® Concrete Bonding Adhesive (No. 9902) permanently bonds new concrete, plaster, and stucco to existing concrete, plaster, and stucco. Eliminates the need for roughing the surface before the application. Exceeds the performance requirements of ASTM C 1059 Type I and II.
Wedge Anchor
Wedge anchors are one of the strongest anchors available.
Molds: Most concrete molds are made from urethane rubbers that resist concrete bonding. Paint: There are no natural bonding agents in paint. Oil: Oil or oiled surfaces create a film that prevents concrete from sticking.
However, patching it requires some attention to detail or your patch will not last. Fact: Fresh wet concrete does not normally bond well to existing dry concrete. Do you remember elementary school where one of the subjects on which you were graded was “plays well with others”?
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.
A concrete bonding agent needs effective adhesion to work correctly, and latex, epoxy, acrylic, and polyurethane are some of the most effective options to choose from.
Yes, Concrete Grinding is ALWAYS required prior to floor levelling otherwise you WILL NOT get ANY insurance on the installation of our product as it's most likely going to fail, crack, or popup within a 3-12 month period due to Floor Preparation not been done correctly.
QUIKRETE® Fast-Setting Self-Leveling Floor Resurfacer (No. 1249-51) can be installed from 1-1/2 inch (38 mm) thick to a feather edge, although a ¼ inch (6.3 mm) minimum thickness is required for heavy traffic areas.
Polymers are used in everything from leather to wood and from computers to paints and metal coverings. Self-leveling concrete is more expensive gallon-for-gallon because of the added cost required to create it. However, this versatile substance can often be used instead of demolishing damaged concrete and replacing it.
