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.
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.
Sand Mix, Portland Cement & Gypsum-Based Compound are practical alternatives to the self-leveling compound. These options are cost-effective materials that are ideal for smoothening up your floor. At the same time, you can also try Drywall Compound and Foam.
Best Self-Leveling Concrete for a Flat Surface—HENRY 565 FloorPro. The HENRY FloorPro is a great floor leveler that can get a flat and smooth surface. This is due to how easy it is to use this self-leveling compound.
Coverage: One 50 Lb. bag will cover approximately 40 Sq. Ft. at 1/8 In.
A faster solution that works for all types of flooring on both wood and concrete subfloors is to use a self-leveling underlayment. Available as either pre-mixed or a dry mix, it's a cement-based material meant to be mixed (if required), poured, then troweled into low spots.
Vinyl and Laminate flooring:
Both vinyl and laminate floors are versatile and durable options that can be installed over slightly uneven surfaces. They are relatively inexpensive, easy to clean and maintain, and come in a wide range of patterns and colors so you don't have to sacrifice style for function.
A good rule of thumb to estimate is that a self leveling concrete floor will cost around $600-850 per 100 square feet.
Pick Your Self-Leveling Cement
Self-levelling cement is a good alternative for levelling without having to fix the entire structure of the floor. Using a self-leveling floor compound will help ensure that the concrete is completely flat before you lay the tiles.
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.
LevelLite® is 40% lighter than other self-leveling underlayments, making it easy to handle, pour, and carry. It helps level floors prior to the installation of ceramic tile, natural stone, resilient flooring, carpet, wood, and other floor coverings.
No. Thin-set mortars are not designed to level floors. Any leveling or sloping of the assembly must be done with an appropriate substrate floor leveling material prior to application of membranes.
Average Cost to Level the Floor in a House
We know, we know… it's frustrating, but it does depend on factors like the size of the slab, the severity of the damage, and the area in which you reside. On average, you are looking at about $3 – $5 per square foot.
However, it is unsuitable for outdoor flooring as it doesn't hold up very well in harsh conditions. Polymer-mixed, self-leveling concrete also does not cure very well on non-horizontal surfaces. It will therefore be unsuitable for use on vertical walls.
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.
It depend on the particular floor leveling product you're using, but most manufacturers recommend that you apply no more than 1/8” thick coat of self-leveling or floor patch compound at a time.
Underlayment can help smooth things out, though, but the type you choose will vary depending on your specific reasoning for wanting an even subfloor. That can make choosing the right one for you rather tricky, so here's a quick guide that should lend a helping hand in getting the best underlayment for uneven subfloors.
You can install vinyl on many types of subfloor, including concrete and wood. But that floor must be flat for your installation to be a success. An uneven subfloor can lead to potential problems, such as planks having varying heights that will make the flooring unstable and wear down more quickly.
Shimming the subfloor is a common method to flatten to required tolerance. Shimming may consist of many variations in technique and a multitude of products to achieve the same goal. Probably the most common method of shimming is using underlayment material to build slight elevation gains.
Many people choose to level their concrete floors themselves. However, using self-levelling compound on a concrete floor depends on how much of the floor isn't level. To accurately measure just how out of level your floor is, you can also use a long spirit level.
LARGE TILES AND UNEVEN FLOORS
This is where the dry pack shines! The drypack bed can be from 1/4" to 3" thick to level the floor if we need to. For basement concrete floors we recommend 2" thickness.
LRB (Liquid Rubber Base) is a self-leveling fluid rubber that will cure as tough as a truck tire, remain permanently flexible. This rubber floor leveler can be applied at any thickness! This 1-gallon Liquid Rubber Base may be used with or without TAV. The LRB self-leveling liquid for concrete is solvent-free.
