How to Install Tigerwood Flooring
To install tigerwood successfully, first confirm whether the flooring is solid or engineered and which installation methods its manufacturer approves. Check the floor structure, flatness, and moisture before laying boards. Then follow the product’s conditioning, fastening or adhesive instructions, and expansion-gap rules. Solid tigerwood is generally nailed only to an approved wood subfloor; concrete needs an approved system.
Could one wrong fastener, damp slab, or missing gap put an expensive tigerwood floor at risk? The safest way to avoid that is to check the product and the jobsite before you open every carton. Tigerwood, also called Goncalo Alves, is a dense hardwood, so careful preparation matters as much as a steady hand with the flooring tool.
I work through the same sequence on every hardwood job: identify the product, check the substrate, plan the layout, and install only with an approved system. Your product’s instructions control when they are stricter than general guidance.
Substrate Inspection, Deflection & Moisture Preparation
The substrate is the surface that supports the flooring, such as a wood subfloor or concrete slab. Before installation, confirm that it is sound, dry, clean, and flat, and that the floor structure can support the finished floor. If any of those checks fail, stop and correct the cause first.
Confirm the product and floor structure
Read the carton and installation guide to identify solid or engineered flooring, board thickness, and permitted methods. Solid tigerwood is commonly installed by nailing or stapling over an approved wood subfloor. Engineered flooring may allow nail-down, glue-down, or floating installation, but not every product allows every method.
For wood-framed floors, the structure should meet at least L/360 deflection under design loads, along with the applicable flooring and building requirements. Deflection is how much a floor bends under load. An underlayment or uncoupling layer does not make a weak floor structure stiffer. If the floor feels springy or framing is uncertain, have it assessed before installing.
Check flatness, movement, and moisture
Use a straightedge to check the subfloor in several directions. A common preparation limit is no more than 3/16 inch variation over 10 feet, unless the flooring maker requires a tighter surface. Sand or plane high spots and fill low areas with a compatible product. Secure loose panels, address squeaks, and remove dust, oil, old adhesive, and coatings that could affect bonding.
Measure flooring and wood-subfloor moisture with a calibrated meter, using the correct setting for each material. Follow the product’s acclimation and moisture-difference limits. Common NWFA guidance for solid boards allows a maximum difference of 4 percentage points when boards are under 3 inches wide, and 2 points when boards are 3 inches or wider. Engineered products have their own requirements.
For concrete, use ASTM F2170 in-situ relative-humidity testing and/or ASTM F1869 moisture-vapor-emission testing as required by the flooring and adhesive makers. There is no universal acceptable RH or MVER limit. Use a complete flooring, adhesive, and moisture-control system rated for your measured result. Never install over damp or contaminated concrete or improvise a vapor barrier.
| Check | What to do | Do not proceed if |
|---|---|---|
| Flatness | Check against the product limit; 3/16 inch in 10 feet is a common maximum | High and low areas remain outside the limit |
| Wood moisture | Record readings for the flooring and subfloor | Readings exceed product limits or moisture difference is too large |
| Concrete moisture | Test by the method the system requires | Results exceed that system’s rating |
| Subfloor condition | Secure, clean, and repair it | There is movement, contamination, or an active leak |
Tigerwood Acclimation, Layout & Installation Precision
Acclimation means conditioning flooring in the room where it will be installed, under the temperature and humidity conditions expected during normal use. Do not rely on a fixed number of days. Follow the manufacturer’s instructions, and record the moisture readings and site conditions before you begin.
Plan the layout before fastening
Check that the building is enclosed and that wet work is complete. Run heating or cooling at the expected service settings, and keep indoor conditions within the product’s stated range. Open cartons only as directed. Mix boards from several cartons as you work, when the manufacturer allows, to distribute natural color and grain variation.
Measure the room and plan board widths at both walls. Avoid ending with an extremely narrow strip; adjust the first row if needed while preserving required clearances. Stagger end joints according to the product instructions, and avoid a repeating stair-step pattern. Dry-lay a few rows to check the look and fit before you commit.
Choose an approved installation method
On an approved wood subfloor, install solid tigerwood with the specified nailer or stapler, fastener type, spacing, and board position. These details depend on board thickness and the subfloor assembly, so follow the product guide rather than guessing. Tigerwood is dense. Use sharp tooling, and predrill where the manufacturer or fastener pattern calls for it to reduce splitting.
For engineered flooring over concrete, use only a method listed for that exact product and substrate: an approved glue-down system, floating assembly, or other specified build-up. For glue-down work, follow the adhesive directions for substrate preparation, primer, trowel size, spread rate, open time, and cleanup. A floating floor must not be nailed or pinned in place.
Illustrative jobsite case 1: If a solid-floor carton is being considered for direct installation on a slab, pause and check the instructions. Solid boards should not be nailed directly into concrete. Select an approved engineered product and complete system for the slab, or use another method only if the flooring maker expressly approves it.
Illustrative jobsite case 2: If wood readings are outside the product’s limit, installing and hoping the floor settles is not a fix. Find and address the moisture source, then retest. Seasonal moisture changes can contribute to cupping, buckling, or joint separation.
These examples show decision points, not reports of specific projects. The next step is to install only after the readings and method meet the product requirements.
Transitions, Perimeter Expansion & Jobsite Safety
Expansion clearance is an open space that lets a wood floor move as indoor moisture changes. The flooring maker sets the required amount. A half-inch gap is common for solid hardwood, but room size, long runs, seasonal conditions, and product instructions may require more.
Preserve clearance at every fixed edge
Leave the required space at walls and other fixed vertical surfaces, including columns, pipes, door frames, and cabinets. Continue the clearance at doorways and other transitions where the floor meets another surface. Cover the gap with trim or a transition piece; do not fill it with hard filler.
Fit trim to the wall, not through the flooring. Do not pin a floating floor with nails, screws, cabinets, or transitions. For any installation type, make sure a transition does not block movement where the product requires a break or expansion space. Use the flooring maker’s detail for wide openings and long runs.
Cut and protect the floor carefully
Measure each cut from the installed edge, account for the needed clearance, and mark the waste side. Use a sharp blade suited to the tool and board. Test a cut on scrap first, especially for visible end cuts and doorways. Keep a stable work surface, wear eye and hearing protection, and follow tool safety instructions.
If adhesive reaches the face, remove it promptly with only the cleaner the adhesive and flooring makers approve. Do not scrape or use solvent without checking compatibility. Check transitions and trim for firm support without trapping the floor.
Cleaning, Finish Care & Long-Term Moisture Protection
A finished floor needs protection from standing water, grit, and large humidity swings. Tigerwood may be sold with a factory finish or unfinished for site finishing, so use care products and finish steps that match the product. Follow the maker’s instructions before moving furniture or cleaning the new floor.
Finish the installation and protect the surface
After installation, fit baseboards or shoe molding without pressing them down so firmly that they restrict floor movement. Install transitions as specified, and check that no fastener passes through a floating floor. Remove dust and adhesive residue with approved products. If the floor is unfinished, follow the flooring and finish manufacturers’ sanding, sealing, and cure instructions.
Use protective pads under furniture, lift rather than drag heavy items, and place mats at exterior doors to catch grit. Clean with the product maker’s recommended method; avoid soaking the floor. Keep indoor humidity within the flooring maker’s range. If moisture problems appear, investigate the source rather than covering the symptoms.

- Use only approved fasteners, adhesive, underlayment, and moisture-control products.
Frequently Asked Questions
Can I nail solid tigerwood flooring to concrete?
No. Do not nail solid tigerwood directly to a concrete slab. Use a product and installation system approved for that substrate. Engineered flooring may allow glue-down or floating installation, depending on its instructions.
Can I install tigerwood over a wood subfloor?
Yes, if the product allows it and the subfloor is sound, flat, dry, and properly attached. Solid flooring is commonly nailed over an approved wood subfloor, using the specified fasteners and pattern.
How long should tigerwood acclimate?
There is no single time period for every product or jobsite. Follow the flooring maker’s conditioning instructions, and confirm site conditions and moisture readings meet its requirements.
How flat should the subfloor be?
A common limit is 3/16 inch over 10 feet, but the flooring maker may require a tighter surface. Correct high and low areas with compatible methods before installation.
How much expansion space should I leave?
Follow the product’s required clearance. Half an inch is common for solid hardwood, but wider rooms, long runs, and other conditions may require more.
How do I test a concrete slab for moisture?
Use ASTM F2170 in-situ RH testing and/or ASTM F1869 MVER testing as required by the flooring and adhesive manufacturers. Compare results with the limits for the complete installation system.
Does an underlayment fix a weak or uneven floor?
No. An underlayment does not correct inadequate joist stiffness or out-of-limit flatness. Repair the structure or substrate first.
Can I use any adhesive or vapor barrier?
No. Choose only products approved for the flooring, substrate, and measured moisture conditions. Follow the full system instructions, including surface preparation and application steps.
