Self-levelling concrete is a polymer-modified cement that has high flow characteristics, it’s used in the preparation of laying most floor coverings to create a smooth and level surface. Levelling compound can be used on a variety of substrates including concrete, screed, existing tiles, and timber floors.
Can you pour self-leveling concrete over subfloor?
If you’ve got a plywood subfloor, like many buildings do, you can leave it in place and apply self-leveling concrete directly on top of it. Once the plywood subfloor is covered, just apply the finish you want to achieve the desired look.
Do I need to prime floor before self Levelling?
Wood floors need to be primed before covering them with self leveler. The floor will be covered with water-saturated leveler, which will cause the wood to swell. It will shrink back down when it dries, which could cause cracks in the underlayment and tiles above. The primer prevents the wood from absorbing water.
Can you put self-leveling compound over laminate flooring?
Self-leveling compound, for example, can be used to flatten out a vinyl floor before laying laminate planks over the top. Keep in mind, though, that installing new flooring over the old means that you are increasing the overall height of the floor.
How do you prepare a floor for self-leveling compound?
Quote from Youtube video: Before sweeping dampen down the area using a plant mister or spray bottle. This will help to keep the dust.
Will self-leveling compound crack?
A DIY self-levelling cement job might look good for a few months, maybe even a couple years. But if it’s not done properly, eventually it can start to crack.
How do you level uneven subfloor?
What can I do with an uneven subfloor?
- Wood underfloors will most likely have to be ripped up and a new one installed to ensure consistency.
- You can also use a flooring underlayment which can smoothen up any remaining peaks and valleys in the subfloor.
What happens if you don’t use primer before self-leveling?
Failure to use product recommended primer may result in installation failure. Primer retains the moisture within the self-leveling underlayment to allow proper curing. Secondarily, it acts as a bonding agent to ensure the SLU bonds properly to the substrate.
What is the cheapest way to level a concrete floor?
There are self-leveling coatings designed to fill gaps and cracks. You could also try using vinyl floor tiles to make the transition more gradual. Probably the easiest (and cheapest) thing to do would be to get a big diamond grinding wheel and bevel down the lip.
How much does a 50 lb bag of self leveler cover?
approximately 40 Sq. Ft.
Coverage: One 50 Lb. bag will cover approximately 40 Sq. Ft. at 1/8 In.
How thick can you go with self leveler?
QUIKRETE® Self-Leveling Floor Resurfacer (No. 1249-50) can be installed from 5/8 inch (16 mm) thick to a feather edge. For areas deeper than 5/8 inch (16 mm), apply QUIKRETE® Self-Leveling Floor Resurfacer (No. 1249-50) in layers no greater than 5/8 inch (16 mm) each.
Can you pour self-leveling concrete over existing concrete?
You can pour self-leveling toppings or self-leveling overlays over concrete surfaces you didn’t think were salvageable, saving time and money. “It’s faster and easier than pouring new concrete,” says Paul Koury, president of Westcoat Specialty Coating Systems.
How thick can you use self-leveling concrete?
It can be easily applied over wood and concrete subfloors at a thickness of up to 3 in. (76 mm). Its high compressive strength at low thicknesses provides superior underlayment performance for higher traffic areas.
Can you put a second coat of self-leveling compound?
Yes, you can add another layer on top of the existing 2 inch layer. You must prepare the floor and use SikaLevel Primer before the second application.
What is the difference between self leveling concrete and self-leveling underlayment?
Self-leveling materials are flowed onto substrate commonly in commercial installations to provide a level surface or a smooth transition, which underlayments may not provide. Self-leveling materials are not underlayment and underlayment is not self-leveling material.

Does MAPEI self leveler need primer?
Suitable substrates include MAPEI epoxy moisture barriers, tile, terrazzo and sandblasted steel decking. Porous substrates like concrete will still require a primer to prevent pinholes and aid in flow of the leveler.
What is self-leveling primer?

Quote from Youtube video: So it soaks into the substrate for non porous substrates.
Can you put a second coat of self-leveling compound?
Yes, you can add another layer on top of the existing 2 inch layer. You must prepare the floor and use SikaLevel Primer before the second application.
Can you use self leveling concrete over painted concrete?
The best way to create a level surface is by pouring an overlay of self-leveling compound. A painted concrete floor can interfere with the leveler, however, preventing the leveler from binding successfully with the concrete.
How thick can you use self leveling concrete?
How Thick Can You Pour Self Leveling Concrete? The thickness depends on the product you use. But standard thicknesses are between ⅛ inch and 1 inch. However, there are mixes that can be poured as thin as 1/16 inch and as thick as 5 inches.
What is the difference between self-leveling concrete and self-leveling underlayment?
Self-leveling materials are flowed onto substrate commonly in commercial installations to provide a level surface or a smooth transition, which underlayments may not provide. Self-leveling materials are not underlayment and underlayment is not self-leveling material.
How do you level an old concrete floor?
The easiest way is to use a self-leveling compound, also called liquid floor underlayment or floor resurfacer, within sections of level-cut rails. The material flows out like thick syrup, then hardens into a smooth, perfectly level surface, sometimes in less than an hour.
