Prepping a plywood subfloor is crucial for hardwood or laminate floors to last.
Put down a 1/4'' luan (plywood) underlayment first. Go the opposite direction of the subfloor. Then you can run your laminate in either direction.
Without underlayment to add a layer between these damp subfloors and the surface flooring, your laminate can quickly become wet, warped, and mildewy, harming its overall integrity. Moisture over time can also break down floor adhesive which causes the floor to start warping.
Underlay protects your laminate against moisture damage
For cold subfloors like concrete, you need to consider a damp proof membrane. Cold ground floor subfloors are often prone to damp, which can damage your laminate. An underlay with a vapour barrier helps prevent this.
Wood naturally absorbs and emits moisture as the seasons and temperatures change, and blocking the exchange of moisture with the air can cause your plywood to become waterlogged, leading to mould or mildew or even buckling. With a plywood subfloor, a foam underlay is the most common choice for laminate flooring.
Laminate flooring is designed to be a floating floor that may be installed over virtually any type of sub floor. And by “floating”, we mean that it doesn't need to be nailed or glued to the sub floor.

Yes, even with attached padding, an additional underlayment can enhance moisture protection and sound insulation. While the attached padding provides minimal benefits, using a separate underlayment will improve the overall performance and longevity of your laminate flooring.
Fibreboard underlay
It helps smooth uneven floors, reduces noise and acts as an excellent thermal insulator. Not to mention, it's also the number one choice of underlay for laminate and wooden floors. If you have an uneven subfloor, the fibreboard will help even any dips and dents you can't level out.
Never use a floor buffer or polisher while cleaning laminate wood flooring. Don't use abrasive or acidic cleaners. Harsh cleaners might strip the protective coating from the floor. Don't use steel wool or scouring powder.
Some laminate flooring planks come with the underlayment attached to each plank. Underlayment is not optional. If your laminate planks don't have it already attached, we recommend that you buy rolls of underlayment on which to install your laminate floor.
No matter which underlayment you choose, if you are installing on a moisture prone subfloor or concrete subfloor, you really need a moisture barrier underlayment.
The answer will vary depending on the material used for the floor and the way that the boards are constructed, but, as a general rule, both Laminate and Engineered Timber floating floors do need some form of underlay to have optimal functionality and longevity.
Underlayment, or “padding” as it's often called, is the spongy, closed-cell plastic foam sheet that comes in rolls. It is rolled out between the actual laminate flooring planks and the subfloor.
If just overboarding then a minimum 6mm thickness is required. However if you are trying to add stability and strength to the subfloor, look at thicknesses from 15 to 22mm.
Polyethylene foam: Polyethylene (PE) foam is one of the most common underlayment materials for laminate flooring. PE Foam underlayments generally do not provide top-tier acoustic performance and moisture protection like an XLPP Foam underlayment, but PE Foam is often a more affordable alternative.
A first option to counter the coolness of laminate flooring is the installation of a quality underlay. It's important to note that we are not talking about paint or a liquid coating, but rather a solid membrane often sold in rolls that is deployed under the laminate floor.
The underlay should be laid foil side down (essential to ensure maximum resistance to moisture from the subfloor) allowing a 5cm excess of underlay to run up the perimeter wall. Each roll of underlay should be closely butted-up.
The built-in underlay not only ensures a smooth and quick installation but also adds cushioning underfoot and helps reduce noise, making your space more comfortable.
uneven floors, use a foam underlayment as the base for your laminate planks. If you determine you need to level the floor, sand the floor and apply a patching compound. If you are installing the flooring below grade or in a room with high humidity or moisture, install a vapor barrier first.
Felt underlayment should overlap the edge metal at the eaves and be overlapped by edge metal on the rakes. This is also true for rubberized asphalt underlayment, but not necessarily true for synthetics. Asphalt-saturated felt may fail for a number of reasons.
Laminate flooring manufacturers typically recommend an underlayment. What happens if you don't put padding under laminate flooring is moisture coming through the subfloor can cause it to warp and mildew. And footsteps on the floor will be louder.
If unprotected, moisture can build up underneath your laminate flooring and cause warping of the planks.
Underlayment is a special grade of APA plywood that is attached on top of the subfloor to provide a durable and resistant layer under finish flooring. Underlayment's special face and inner-ply construction resist dents and punctures from concentrated loads.
