Keeping an underlay in place depends on your subfloor and the type of flooring you are installing. Generally, you secure it by using staples for timber subfloors, spray adhesive or double-sided tape for concrete, and seam tape to connect the rolls.
Not always. Gluing is recommended on concrete floors where staples can't be used. Timber floors usually work best with staples. In some cases, underlay can stay in place with tape and carpet pressure alone.
A specialized acoustical underlayment—like cork or rubber—can be glued down before the hardwood floor is installed, helping to dampen noise and increase underfoot comfort. Although this is not a typical requirement for single-unit homes, it may be specified if you desire quieter rooms or if building codes require it.
Yes, taping is recommended when laying underlay for laminate, especially if you're working with rolls. Using tape helps to secure the edges and keep the underlay in place, preventing it from shifting during the installation of your laminate flooring.
Duct tape can be used for underlayment and benefits from advantages, such as the fact that it's cheap and readily available. On the other hand, there are several different specialised underlayment tapes available.
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. Tape all joins with single sided waterproof tape and press firmly into place.
Fasten the underlayment with either staples or nails. Start on one corner of the panel and fasten the 8' edge first, spacing 2” along the entire edge. Make sure the fastener is around 1/2” from panel edge. Go back to the starting corner and repeat the process along the 4' edge.
It is sometimes necessary to glue down an underlay. For example, in a double-stick installation, underlay is glued to the sub-floor using a release type adhesive.
Rather than nails, screws are best to use for subfloors — these fasteners are convenient, easy to remove and capable of providing torque that nails lack. Because of their structure, screws can penetrate plywood more easily and improve the connection, whereas nails can weaken the plywood.
The Foundation of Stability: Choosing the Right Non-Slip Underlay. One of the most effective and widely adopted solutions for stopping mats from moving on carpet is the strategic use of a dedicated non-slip underlay, often referred to as a rug pad or gripper pad.
However, during installation some installers like to fasten underlayment to the subfloor to prevent the underlayment from moving or rolling back, which is a nuisance. If your choose this route, staples are a good choice to fasten the underlayment. Staples usually have a coating which help increase the holding power.
Traditional felt underlayment remains a popular choice for many roofing projects due to its affordability and proven track record. Standard #15 felt typically provides reliable protection for 15 to 20 years under normal conditions, while heavier #30 felt extends this timeline to 20 to 30 years.
Each stapler is engineered for power, durability, and ease of use, helping fitters work more efficiently without compromising on finish. Paired with our high-quality staples, you can tackle everything from underlay fitting and carpet installation to securing trims and accessories with confidence.
Yes, absolutely! Not only is it possible to lay your own underlay, for most projects we actually recommend it. Even if you're a bit of a DIY amateur – and have no previous experience in this area – most underlays are now designed with easy installation in mind.

Screws are preferred over nails for subfloor and underlayment installations as they provide strong and tight connections that help prevent the floor from squeaking.
Nails bring a few benefits to your project, but it depends on what kind of project you're up to. Nails are a favorite for large jobs in construction because they're cheaper than screws and offer shear strength — or the ability to withstand shear pressure, where two surfaces slide past each other.
Gluing plywood underlayment panels to the subfloor can cause problems such as a tack and release floor that crackles when you walk across it. In addition, gluing the underlayment panels to your structural subfloor will eliminate the opportunity to remove the underlayment for a future floor replacement.
Double Glue Down Underlayment Installation
If your chosen underlay does not have integrated adhesive tape, use dedicated 50 mm wide aluminum tape to seal the joints. This will prevent the strips from shifting. Once the surface is prepared, you can start laying your laminate flooring.
Stick your underlay to your subfloor – use adhesive glue or staples to make sure that your underlay is firmly attached to your subfloor. Lay your carpet on top – Now you can have your carpet fitted on top. Remember that caring for your carpet is the most important way to look after your flooring and your underlay.
First, roll out a piece of underlay and push it up to the wall. Make sure you install the underlay in the same direction as you're planning on installing the floor. Put a box of planks on it to hold that end in place before rolling out the rest in the other direction. Then, cut it off at the nearest perforated edge.
No subfloor is perfectly level, but any signs of unevenness and high or low spots must be remedied. Please follow these requirements: Subfloor unevenness cannot be greater than 3/16 of an inch over a 10-foot span or 1/8 inch over a 6-foot span.
Although a minimum 11/32-inch thickness is recommended, 1/4-inch plywood Underlayment may also be acceptable over smooth subfloors, especially in remodeling work.
