Plywood underlayment is typically needed when a floor material must have a very smooth, flat surface. For example, if you install resilient tiles or sheet flooring over a subfloor, any bumps, dips, or voids in the subfloor may be evident in the finished flooring.
Underlayment for laminate flooring is a must. Since laminate is a floating floor, it must be evenly distributed across your subfloor. Underlayment is what allows the floor to float, gives it stability, support, noise reduction, and supports the locking systems in between planks to assure the sturdiest flooring project.
Laminate floors can be installed directly over concrete, plywood, OSB, parquet, vinyl and tile. The underlayment must be applied to the original flooring surface first, and then the floating floor can be installed.
While there are a number of good options in the market, cork and foam are the usual favorites for a laminate floor underlay. Depending on your lifestyle, you may appreciate cork for its thickness and sound absorption; foam, on the other hand, is an excellent, cost-efficient material that works as a moisture barrier.
Some experts suggest that 15/32-inch plywood should be standard if the underlying floor joists are spaced 16 inches apart or less, but you should use slightly thicker 3/4-inch plywood for joists spaced further apart. However, check with your local code authorities for the official recommendations.
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. Protect your laminate flooring from moisture for years to come by installing moisture barrier underlayment.
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.
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.
Don't install your laminate on any floor with a drain. Don't install laminate on any uneven subfloor or outdoors. Don't install your laminate over residential carpet. Don't install a second layer of laminate underlayment.
In the end, it's your decision if moisture protection and getting higher sound absorption is your goal. If not, then pre-attached underlayment will do it's job but at the minimum.
Plywood tends to splinter, making it difficult to cut designs into your floor. You may also have to use timber or decorative mouldings to cover up the layers that are visible along the edges of your floor. While it has some water-resistant qualities, moisture will still weaken a plywood floor.
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.
The underlayment helps the laminate planks lay smoother, connect better, and for the flooring to feel slightly softer underfoot. Underlayment is either pre-attached to the bottom of the laminate flooring by the manufacturer or it is installed separately by the user.
If you're installing a new floor, pedestal sink, and toilet, you should install the laminate flooring first so it's under the sink and toilet. Because laminate flooring floats above the sub-floor on top of underlayment, it will expand and contract slightly with the temperature and humidity of the room.
In order to preserve and protect the wear layer, make sure any cleaning product you buy or DIY is safe for laminate flooring. Products that are oil-based, acidic or abrasive can damage the surface. Similarly, never polish or wax your floor. Remember, laminate flooring cannot be refinished if it is damaged.
In fact, you can cut the planks using a table saw, miter saw, circular saw, hand saw or laminate cutter. However, using a diamond blade is recommended as laminate can be tough to cut through and may damage another type of blade. Typically, you will cut with the finished side up.

In short, vinyl flooring itself can be completely self sustainable and does not require an underlayment to function properly. Another reason underlayments may be suggested for vinyl flooring is if the vinyl flooring type is thin. When the vinyl flooring is thin, it becomes a lot easier to flex and bend.
Laminate flooring cannot ever be installed on a subfloor made of carpet or padding. Wood and concrete are the idea subfloors. In some instances, you might be able to install your flooring over an existing floor, but it is important to check prior to installation if it is a suitable material.
Plywood underlayment is the layer of plywood that is fastened over the structural subfloor. It creates a uniform, smooth surface for resilient flooring, vinyl tile, ceramic tile, carpet, engineered flooring, and wood floors.
Your plywood would most likely be on a sleeper system (floating wood planks on concrete). Having a vapor barrier below the sleepers is ideal as moisture will not get to the plywood. Regarding on-grade applications, if their is a basement underneath, then you will not need a vapor barrier on top of the plywood.
