One of the advantages engineered hardwood has over solid hardwood is installation flexibility. Depending on your subfloor type and location in the home, engineered hardwood installation can be done three different ways: floating, glue-down, or nail/staple-down. Each method has its strengths — and the right choice for your Edmonton home depends on a few key factors.
Method 1: Floating Installation
In a floating installation, the planks are clicked or glued together at the edges but are not attached to the subfloor. The floor essentially “floats” as a single connected unit on top of an underlayment layer.
How It Works
Most floating engineered hardwood uses a click-lock tongue and groove system — planks snap together without adhesive. Some products use a glue-together floating method where adhesive is applied to the tongue and groove joints, not the subfloor.
Best For
- Concrete subfloors on grade and below grade (with moisture barrier)
- Installations over existing flooring where height allows
- DIY-friendly applications where the product specs permit it
- Rental properties where future removal and reinstallation is a consideration
Edmonton Considerations
Floating floors move as a single unit with seasonal humidity changes — expansion gaps around the perimeter are essential. In Edmonton’s dry winters, failing to maintain adequate expansion gaps can cause the floor to buckle as it contracts and expands. A quality underlayment with a built-in moisture barrier is strongly recommended on concrete.
Limitations
Not all engineered hardwood products are approved for floating installation — particularly thicker, heavier planks. Check manufacturer specs. Floating floors can also feel slightly less solid underfoot than glued or nailed installations.
Method 2: Glue-Down Installation
In a glue-down installation, each plank is adhered directly to the subfloor using a compatible urethane or moisture-cure adhesive. This is the standard method for engineered hardwood over concrete.
How It Works
The installer spreads adhesive on the subfloor using a notched trowel, then places each plank directly into the adhesive. The floor is fully bonded to the subfloor once the adhesive cures — typically 24 hours.
Best For
- Concrete subfloors on grade and above grade
- Edmonton basement installations over dry, conditioned concrete
- Large open areas where a floating floor’s movement might be problematic
- Radiant in-floor heating systems — a glued floor transfers heat more efficiently
Edmonton Considerations
Glue-down is the most stable installation method in Edmonton’s variable humidity environment. Because the floor is fixed to the subfloor, individual plank movement is minimized — the adhesive layer also provides some moisture buffering. Moisture testing of the concrete is essential before gluing; excess moisture will compromise the adhesive bond.
Limitations
More labour-intensive than floating — and permanent. Glued floors are significantly more difficult to remove or replace. Not all adhesives are compatible with all engineered hardwood products; always use manufacturer-recommended adhesive.
Method 3: Nail or Staple Down
Nail-down and staple-down installation attaches each plank to a wood subfloor using a pneumatic nailer or stapler through the tongue of each plank. This is the traditional installation method used for solid hardwood, and it’s available for engineered hardwood products with sufficient thickness and plywood cores.
How It Works
A pneumatic floor nailer or stapler drives fasteners through the tongue of each plank at a 45-degree angle into the wood subfloor. The fasteners are hidden by the groove of the next plank, leaving a clean surface.
Best For
- Wood subfloors (plywood or OSB) above grade
- Main floor and upper-level installations in Edmonton homes
- Engineered hardwood with plywood cores and sufficient thickness (typically 1/2 inch or thicker)
- Homeowners who want the most solid, traditional-feeling floor
Edmonton Considerations
Nail-down engineered hardwood on a well-prepared wood subfloor feels and performs similarly to solid hardwood — it’s the most rigid and stable-feeling installation. In Edmonton’s older homes where subfloor condition may vary, thorough subfloor preparation is critical before nailing begins.
Limitations
Not suitable for concrete subfloors without a plywood sleeper system. Not all engineered hardwood is thick enough or has the right core for nail-down installation — thinner products and HDF-core engineered hardwood are typically floating only.
Which Method Is Right for Your Edmonton Home?
- Concrete subfloor (basement or on-grade slab): Glue-down or floating with moisture barrier
- Wood subfloor above grade (main floor, upper level): Nail-down, staple-down, or glue-down depending on product
- In-floor radiant heating: Glue-down — best heat transfer and stability
- Budget-conscious or DIY project: Floating — most accessible installation method
- Maximum stability and solid feel: Nail-down on wood subfloor
The right installation method also depends on the specific product you’ve chosen — not all engineered hardwood supports all three methods. The team at LCF Flooring will assess your subfloor, confirm which installation methods your chosen product supports, and recommend the best approach for your home.
