The best flooring for uneven floors due to its attractiveness and durability is epoxy, which can also be designed to mimic a wide variety of appearances.
For very uneven flooring, laminate sheets or tiles may be a better bet. This material is more flexible, but may reveal the imperfections in the surface. The most durable and attractive option for an uneven floor is often a pour on option, such as epoxy.
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.
Planks installed on an uneven floor can also lead to hollow spots, bouncing floors, and flooring joints separating, breaking, or splitting, causing the floor to fail. Tip: Use a level or straight edge to ensure the floor is flat before installing your vinyl.
If you're installing vinyl planks on top of a concrete floor, the standard tolerance required is for the floor to be level to 3/16” within a 10' radius. It also can't have a dip of ⅛” within 2'. Level means that a floor doesn't slope in any direction.
Floating Floor – The Best Floor For Uneven Surface
Installation of floating floors are easy and fast because planks click or snap together quickly and “float” above the subflooring surface. A typical floating floor application is done using either wood, laminate or luxury vinyl tile flooring products.
Uneven floors in a house are usually a sign of a foundation problem, but not always.
Forgetting to level the subfloor
The subfloor must be level before installing laminate flooring. If the subfloor is leveled, the laminate planks will not lay properly, causing uneven and unsightly floors. If the subfloor is not level, you can use a self-leveling compound to level it out.
You can't go wrong with vinyl that's designed to go directly over concrete. Vinyl is durable, easy to install, and highly moisture-resistant. The best options for both appearance and ease of installation are vinyl planks and sheet vinyl.
Vinyl tile and vinyl plank flooring are easy to install, thanks to interlocking joints. What's more, you can get these materials in an amazing variety of styles. This flooring can be made to look like different wood species, or to resemble ceramic tile. Most types can be installed over concrete or over a subfloor.
If your subflooring has bumps or dips you'll want to get rid of those before installing your laminate flooring. It's important that the surface is nice and flat for the laminate to be installed. You can use a floor leveling compound to any dips and let it dry thoroughly before moving on.
First, the slipping started, because peel-and-stick vinyl tiles don't actually stick that well to uneven surfaces. Sure, they make great contact with flat areas, but grout lines pose a bit of a problem. And moldings and appliances, too. You need laser precision to cut these babies flush to the footprint of your space.
If mixed to the correct consistency, self leveling underlayment will spread out when poured onto a surface and seek its own level, lessening the labor required for a very thin coat. If the material is mixed too densely, it will not flow easily and will usually require additional troweling.
If you want to raise the height of a floor, the cheapest and easiest way is to add a thick underlayment designed for the job. There are other options too like adding a framed wooden subfloor or floor leveling compound before installing new flooring.
Average Cost to Level the Floor in a House
On average, you are looking at about $3 – $5 per square foot.
One of the best ways to fix the issue of uneven floor is to use floor patch product. It can be used in concrete subfloor or wooden subfloor. It is best for leveling floors that has dips, slanting issues, cracks and chipping problems.
Uneven or sloping floors are very common in older homes, and while it's often a sign of structural damage, it doesn't have to be a dealbreaker.
It can be heartbreaking, but sometimes your only real choice when dealing with foundation issues is to walk away. If the seller won't make repairs, the damage is too extensive or you can't wait for repairs to be completed, you may have no choice but to give up and find your next dream house.
You need a dry, clean and flat surface before you can install finished flooring in a room built on a concrete slab. One of the simplest options is a sleeper-based subfloor. The result is a subfloor that protects finished flooring from cold and damp concrete-based floors.
Fibreboard Underlay
It works to smooth uneven floors, reduces noise, and acts as a thermal barrier. If the subfloor is uneven, fibreboard works to even dips and dents you can't level out. It's also necessary to add a DPM if you're installing fibreboard on top of a concrete subfloor.
The best option for slightly uneven subfloors is a direct stick installation (involving nails & glue) if this is a viable option. Floating flooring is not recommended for uneven floors as this increases risk of the planks moving or splitting apart.
