Full-spread glue-down solid hardwood installation over a concrete slab in Orlando, FL — the correct method for Florida's climate, delivering a stable, quiet, and beautiful floor that lasts decades.

Project Overview
Solid hardwood remains one of the most desirable flooring options for Florida homeowners — the warmth, character, and timeless beauty of real wood is difficult to replicate, and solid hardwood floors can be refinished multiple times over their lifetime, making them a generational investment rather than a consumable product. But installing solid hardwood in Florida requires a different approach than in northern climates, because virtually every Florida home is built on a concrete slab rather than a wood-framed subfloor.
This Orlando residential project involved the installation of solid hardwood flooring using the full-spread glue-down method — the industry-standard approach for solid hardwood on concrete in Florida and the only method recommended by most solid hardwood manufacturers for slab construction. Every board was bonded directly to the prepared concrete substrate with a moisture-tolerant urethane adhesive system.
Why Glue-Down for Solid Hardwood on Concrete
Homeowners sometimes ask whether solid hardwood can simply float over concrete, as LVP does. The answer, for solid hardwood, is no — for several important reasons specific to Florida conditions:
Solid hardwood moves with humidity: Solid hardwood expands and contracts significantly with Florida's humidity swings — more so than engineered hardwood or LVP. Without being bonded directly to the slab, this movement creates gaps in dry seasons and crowning in humid seasons.
Nail-down is not possible on concrete: The traditional nail-down method used on plywood subfloors cannot be applied to concrete — there's nothing for a nail or cleat to bite into.
Glue-down creates a monolithic floor: When each board is bonded fully to the slab with a urethane adhesive, the entire floor system becomes stable — no movement, no hollow spots, no rocking or deflection underfoot.
Florida moisture control: Moisture-tolerant adhesives used in glue-down systems provide a vapor barrier function, protecting the wood above from moisture vapor emitting from the concrete slab — a significant concern in Florida's high water-table environment.
The Installation Process
Glue-down solid hardwood installation requires careful preparation and a systematic process that can't be rushed. The concrete subfloor was ground flat, moisture-tested, and verified within the adhesive system's moisture tolerance before any hardwood was delivered to the site. The hardwood was allowed to acclimate in the installation space for a full week with the HVAC system operating — a critical step that cannot be shortened without risking post-installation movement.
The installation sequence proceeded from the starting wall with careful attention to straightness — any deviation in the first few rows propagates and amplifies as installation continues across the room. Adhesive was applied with the specified trowel notch size, boards were seated firmly into the adhesive bed and tapped tight with a rubber mallet and pull bar, and row straightness was verified every few rows.
The final result was checked for hollow spots (areas where the board didn't fully seat into the adhesive) by walking the floor and listening for any flex or hollow sound — a step that catches any bonding issues before they become post-installation callbacks.
Results: Real Wood, Properly Done
The completed solid hardwood floor looked exactly as real wood should — with the natural variation in grain and tone that no engineered product fully replicates, and with the solid, quiet underfoot feel that only a properly glued-down installation provides. The homeowner had previously lived with a floating LVP floor and specifically wanted the premium experience of solid hardwood installed correctly — and that's what this project delivered.

Frequently Asked Questions
In Florida, virtually all residential floors are on concrete slabs, and solid hardwood cannot be nailed directly to concrete. The glue-down method bonds each board directly to the concrete with a moisture-tolerant adhesive, preventing movement, cupping, and squeaking. The solid adhesive bond also provides better stability in Florida's high-humidity climate compared to floating systems, which can move and deflect under foot traffic.
Glue-down hardwood on concrete requires a specialized hardwood flooring adhesive — typically a urethane or MS polymer system that provides moisture resistance, elasticity to accommodate wood movement, and strong permanent bond strength. We never use standard construction adhesive for hardwood installation. The specific adhesive is selected based on the wood species, the concrete moisture vapor emission level, and the manufacturer's requirements for warranty compliance.
Yes — solid hardwood can be successfully installed over concrete in Florida using the glue-down method, provided the concrete subfloor meets flatness requirements, moisture vapor emissions are within the adhesive system's tolerance, and the wood is properly acclimated before installation. Cavalieri Flooring performs all required testing and prep before any hardwood is glued down to ensure a successful, long-lasting result.
Solid hardwood typically needs 5 to 7 days of acclimation in the installation environment — stored in the room where it will be installed, with the HVAC system running at normal operating conditions. In Florida's humidity, acclimation is critical: hardwood installed before it has reached equilibrium moisture content with the room will move after installation, potentially opening gaps or causing crowning.
