Should I glue my hardwood flooring?

Posted: January 22, 2024

Deciding whether or not it is worth gluing hardwood flooring with or without nailing during installation involves several factors, including the type of hardwood, subfloor conditions, width considerations, and project-specific requirements. Here are essential factors to consider before gluing hardwood floor to subfloor:

  1. Hardwood Type: The suitability of gluing down hardwood flooring depends on the type of hardwood you’re working with. For example, thin engineered hardwood (typically 1/2″ thick or less) is often a prime candidate for glue-down installation due to its minimal wear layer and slim plywood core. Solid hardwoods like our rustic Hickory flooring, which are from a less stable wood species, are also a good candidate compared to a more stable wood species like our Douglas Fir wood floors.
  2. Subfloor Conditions: The choice of installation method is significantly influenced by the type and condition of your subfloor. Typically, gluing hardwood flooring is well-suited for concrete or plywood subfloors. To prevent squeaks and ensure a secure bond, the subfloor must be clean, level, and dry.
  3. Width Considerations: The width of a hardwood floor is also important to consider. Typically wider widths, depending on species, can benefit from a glue assist installation since they are more susceptible to movement. This also helps with the inevitable squeaks that can occur over time.
  4. Moisture Resistance: A full trowel glue down using a mastic glue can create a moisture barrier which is ideal for spaces with high humidity or moisture concerns. Wider planks should be acclimated to the environment and can benefit from added adhesive to counteract potential cupping and movement.
  5. Acoustic Advantages: Gluing down hardwood flooring can improve sound insulation and reduce noise, which is crucial in multi-story buildings or areas where sound control is a priority.
  6. Warranty and Manufacturer Guidance: Always adhere to the manufacturer’s installation recommendations, which may specify the preferred installation method and plank widths for their particular product. Following these guidelines is essential for both warranty compliance and long-term floor stability.
  7. Skill and Experience: Proper adhesive application is essential for successful glue-down installations. When working with wider planks, extra care must be taken to ensure an even spread of adhesive to prevent cupping and gaps. Experience installers are better equipped to handle the nuances of wide plank gluing.
  8. Budget Considerations: It’s important to acknowledge that gluing down hardwood flooring, especially wider planks, may require more adhesive and labor, thus impacting the overall project budget. However, the investment is often justified by the durability and stability of the floor.

In certain situations, it may be advisable to combine installation methods, such as gluing down narrower planks of hardwood flooring and potentially nails or staples for wider ones, based on subfloor conditions and project specifics.

Before proceeding with gluing hardwood floor to subfloor, consult the manufacturer’s guidelines and, if necessary, seek guidance from a professional hardwood flooring installer. They can evaluate your project’s unique conditions, provide recommendations tailored to width considerations, and guide you toward the most suitable installation method for your specific situation.
