![]() No matter how the slab looks, moisture deep in the slab can migrate to the surface over time and cause serious problems. This isn’t something you can do just by looking at the slab. So you need to test the slab to ensure the moisture level is not too high. All concrete contains moisture, and if the moisture level is too high, it may cause the leveling compound to degrade over time. Preparing to Use Self-Leveling Compoundīefore installing your new floor, there’s an essential consideration you need to address: moisture in the existing concrete floor. Concrete toppings can also receive pigmented color dyes, stains, saw cuts or mechanical polishing to produce a decorative concrete finished wear surface. Other concrete toppings applications include warehouse floors, light industrial applications, retail stores, and institutional facilities. Maybe you’re finishing a basement where the floor is rough and uneven concrete. Maybe you’re building an addition and must match the floor to the floor in an adjoining room. Or maybe you’re installing a radiant heating system in a floor. Let’s say you’re upgrading an old, damaged concrete floor that’s settled or cracked. If you do, quickly and carefully scoop it up into a bucket and remove it. Be careful not to pour more product than you need.If you allow the product to set it will never come off. Clean all tools and buckets immediately when you’re done.Do not add water to the product while spreading it.Do not mix products in extremes of heat or cold.Keep your leveler product dry – store the bags indoors and up off the ground.Once you pour, you may only have about 10-20 minutes to work. Have all your tools and supplies ready.You must finish the job in one pour so you can’t return to the store for more. A difference of a fraction of an inch in thickness can mean several bags of product. And if any of these tips conflict with the instructions, go with the manufacturer’s process instead. Read and follow the manufacturer’s instructions to the letter.Installing Self-Leveling Concrete 7 Tips for a Better Concrete Installation: ![]() You can also visit the International Concrete Repair Institute (ICRI) for more information on next steps or to find an expert to help. If you find moisture is a problem in the slab, you need to get a professional to handle the moisture remediation. The thicker floor-leveling compounds that must be troweled to achieve a proper finish can’t do this. Self-leveling concrete works especially well with radiant heating installations because it easily flows around the tubing. But if the concrete floor has low spots and needs to be smoothed even more, it can be poured as thick as an inch and a half without adding aggregate and 5 inches with the addition of aggregate (though make sure you follow all manufacturer’s guidelines). Self-leveling concrete can be poured as thin as a quarter of an inch, just enough to smooth out small imperfections if that’s all you need. They have the strength of concrete but flow more easily and are set up quickly. ![]() They’re generally mixtures of Portland cement, polymer plasticizers, and other ingredients.

The product is mixed with water, pumped or poured into place, and spread evenly with a gauge rake. But unlike concrete, it flows easier and sets up much faster.

Self-leveling concrete can be a fast, cost-effective solution to the problem whenever you need to repair, smooth, or raise a floor.
