Can you put laminate on uneven floor?
You should not put laminate on an uneven floor. Laminate that is installed on an uneven floor will settle into the uneven surfaces. This will affect the quality of the final product. The dips in the subfloor will create an air gap under the boards, which is what causes laminate floors to pop and creak under your feet.
Can you use self-leveling compound on wood subfloor?

How flat does subfloor need to be for laminate?

How do you fix an uneven subfloor?
For concrete slabs: If there are only a few problem areas in the concrete, you can mechanically flatten them by grinding, bead-blasting, abrading, or using a patching compound. If the entire slab is uneven, you may have to use a self-leveling concrete compound to smooth it out.
How do you fix uneven wood subfloor?
Use Self-Leveling Compound to Correct Subfloor Wide sags and depressions in a floor sometimes can’t be adequately bridged even by sheets of plywood, so it’s best to fill these areas with self-leveling compound. When mixed with water, the compound settles into low areas and dries to a smooth, level surface.
Can you use underlayment to level floor?
Use an underlayment, floor leveler or floor patch product to fix low spots in a wood or concrete subfloor. An underlayment is a thin layer of material sandwiched between two other materials. Pour the liquid-like floor leveler onto the subfloor and smooth it out with a trowel.

Does floor leveler crack?
It will cost you but, as always, you get what you pay for. 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. If your floors move or bounce, that cement can crack, too.
Do I need primer for self-leveling compound?
Self-leveling underlayments require the use of a primer prior to installation (like the TEC Multipurpose Primer). Failure to use product recommended primer may result in installation failure. Primer retains the moisture within the self-leveling underlayment to allow proper curing.
Does floor need to be perfectly level for laminate?
The only leveling you need to do is to smooth out the surface to get rid of any bumps or dents. This is the foundation on which you surface (finished) surface rests. It gives sturdiness and balance and is attached to the floor joists. In a kitchen, appliances are usually attached to this surface.
Why is my laminate floor not laying flat?
Laminate flooring is said to float because it is not fastened to the sub-floor. All the individual pieces interlock into one sheet that lays or “floats” on the sub-floor. When properly installed it should have a gap of approximately 1/4 inch from the walls of the room on all sides.
What if subfloor is not level?
Obviously, if plywood is not leveled before installing the underlayment and the flooring, the flooring can crack, break, and become uneven, which is a safety hazard.
What do you put on top of subfloor?
Underlayment: Some types of flooring can be installed directly on top of the subfloor, such as vinyl flooring. Other types need a middle layer, called underlayment, such as laminate,carpet and tile.
Does underlayment help with uneven floors?
An uneven sub-floor can cause issues to arise prematurely even if the floors are top-notch. Underlayment can serve as a relatively simple fix to an uneven-subfloor. If all for sides of the room’s perimeter are level, then underlayment should work for you.
How do you fix a low spot under a floating floor?
Soft spots in a laminate floor can be caused by an uneven sub-floor or improper installation of flooring underlayment. For quick repairs of soft spots in your laminate floor use an air inflation needle or a syringe (used to blow up sports balls) on a can of spray foam.
How do you level a laminate floor after installation?
Knock down humps with a belt sander and a 100-grit sanding belt. If the floor is concrete and the humps are large, you may need to chisel them down with a hammer and a cold chisel. You can also spread floor leveling compound over the entire exposed subfloor to level it.
