Liquid Nails is not the first recommendation for stair treads due to its high water content
Liquid Nails is a well-known adhesive brand that can be used for securing stair treads. However, it is not the first recommended adhesive for this application due to several factors, especially its high water content.
High moisture levels in adhesives can cause warping and buckling in solid wood stair treads. Liquid Nails products tend to have a greater amount of moisture than what is suitable for solid wood. This can lead to cupping and severe warping issues, requiring costly replacements. The excess moisture can also prolong the curing process, extending the project timeline beyond what is desired.
Additionally, Liquid Nails products have similar labelling and packaging across different formulations, which can lead to incorrect adhesive selection. The specific formulation of the adhesive is crucial for optimal results when securing stair treads. The chosen adhesive should be designed for stair treads and take into account factors such as water resistance, flexibility, durability, and initial grab.
While Liquid Nails does offer a formulation specifically designed for stair treads, such as Liquid Nails Cove Base & Stair Tread Adhesive (CB-10), it can be challenging to source due to inconsistent product availability across retailers. This inconsistency has led to concerns about the potential for serious consequences, including complete product failure.
For these reasons, other adhesives with lower moisture content, such as polyurethane glue (e.g., Loctite PL Premium), are often recommended over Liquid Nails for installing stair treads. These alternatives provide a stronger initial bond, reducing the need for additional bracing during the curing process. They also minimize the risk of moisture-related problems, ensuring a longer-lasting and more durable bond capable of withstanding heavy foot traffic.

For best results, use finishing nails with adhesive to act as a pressure hold
When installing stair treads, it is essential to use the appropriate adhesive formulation and meticulously prepare the surfaces to ensure a secure and aesthetically pleasing staircase. While Liquid Nails can be used to hold stair treads, not all products are suitable for this application, and the selection of the correct formulation is critical. For instance, the Liquid Nails Cove Base & Stair Tread Adhesive (CB-10) is specifically designed for stair treads and offers a strong initial grab, water resistance, flexibility, and durability.
To achieve the best results, it is recommended to use finishing nails in conjunction with the adhesive. The nails serve as a "clamp" to provide ""clamping" pressure on the adhesive, ensuring that the treads remain securely in place while the adhesive dries. This combination of nails and adhesive is particularly advantageous when working with a slope, as it minimizes slipping and ensures a firm bond.
When using finishing nails with adhesive, it is important to follow these steps for optimal results:
- Prepare the stair treads: Ensure that the stair treads are clean and dry. Wipe down the back of the treads with a clean cloth to remove any dust or debris. If using wooden treads, properly acclimate them to the environment to minimize the risk of warping or movement after installation.
- Apply the adhesive: Follow the manufacturer's instructions for the chosen adhesive. Typically, this involves applying a continuous bead or zigzag pattern of adhesive to the back of the stair tread or the subfloor, using a caulking gun for precise application.
- Position the tread: Carefully position the tread onto the subfloor, aligning it with the riser and adjacent treads. Ensure proper overhang or nosing projection as required by building codes.
- Secure with finishing nails: Use finishing nails to act as a pressure hold, providing additional support while the adhesive dries. The nails should be placed in such a way that they apply even pressure to the tread, ensuring good contact with the adhesive.
- Allow drying time: Refer to the manufacturer's instructions for the recommended drying or curing time for the adhesive. During this period, the finishing nails will continue to provide clamping pressure, ensuring that the treads remain securely in place.
By following these steps and using finishing nails with adhesive, you can achieve a strong and durable bond for your stair treads, resulting in a secure and aesthetically pleasing staircase.
