If you’re looking to upgrade your home with a floor that’s equal parts durable, elegant, and timeless, teak wood flooring is hard to beat. As someone who’s been in the teak wood flooring supply business for over 12 years—working directly with homeowners, contractors, and designers to source high-quality, sustainably harvested teak— I’ve seen firsthand how a do-it-yourself (DIY) installation can save you thousands of dollars, while also giving you the satisfaction of completing a project that adds real value to your space. That said, teak flooring isn’t like laminate or vinyl; it requires a bit of prep, precision, and patience. I’ve guided dozens of DIYers through the process, and today I’m breaking down every step to help you get it right. Teak Wood Flooring
Before we dive in, let’s set a quick expectation: this isn’t a weekend project (unless you’re a seasoned DIYer). Most people take 3 to 5 days, depending on the size of the room and how much prep work your space needs. The biggest mistake first-timers make is skipping critical prep steps, which leads to warped planks, uneven floors, or gaps that open up over time. I’ll also share tips that come straight from our team’s experience—things we’ve learned testing planks, troubleshooting issues, and making sure your teak floor lasts for decades.
First, let’s talk about why teak is worth the extra effort. Unlike pine or oak, teak has natural oils that make it resistant to moisture, scratches, and even minor insect damage. That means if you live in a humid climate (think the Southeast U.S., or coastal areas) your teak floor will hold up far better than other hardwoods. And since we source our teak from FSC-certified farms, you won’t have to worry about contributing to deforestation. If you’re just starting to pick out planks, reach out to our team before you buy—we’ll help you select the right grade (we carry natural, engineered, and solid teak planks) for your space, and even send a small sample so you can test the color and texture in your home.
Now, let’s get to the installation.
Step 1: Prep Your Space (The Most Important Step)
I can’t stress this enough: bad prep equals a bad floor. Before you even unbox your teak planks, you need to make sure your subfloor is ready, and the room’s environment is stable.
First, acclimate your planks. Teak, like all wood, expands and contracts with changes in temperature and humidity. If you install planks straight from the box into a cold, dry basement, they’ll shrink and leave gaps; if you install them in a hot, humid upstairs bedroom, they’ll swell and buckle. That’s why acclimation is non-negotiable. Here’s how to do it right:
- Lay the planks flat in the room where you’ll be installing them, in their original packaging (or if you’re worried about moisture, leave the ends slightly open so air circulates around each plank).
- Let them sit for at least 7 days, and 10 days if your room is in a very dry or very humid climate. Check the room’s humidity levels—aim for 30% to 50% humidity, and a temperature between 60°F and 80°F. If your space is too dry, use a humidifier; too humid, use a dehumidifier.
- Pro tip from our team: If you’re working with solid teak planks, take one plank out and measure its width. Check it daily for 7 days—if it expands or shrinks more than 1/8 inch, it’s not acclimated enough. Wait another few days before moving on.
Next, prep your subfloor. The subfloor is the base your teak planks will sit on, and it needs to be completely level, clean, and dry. For most homes, the subfloor is either concrete (for ground-level or below-grade spaces) or plywood (for above-grade, frame-built homes).
- For concrete subfloors: First, check for moisture. Concrete can emit moisture over time, which will warp your teak planks. Use a concrete moisture test kit—you can pick one up at any home improvement store, and it takes about 24 hours to complete. If the moisture level is over 4 pounds per 1,000 square feet, you’ll need to apply a moisture retarder coating before installing your planks. Next, make sure the floor is level: use a long level (4 feet or longer) to check for high or low spots. If there are high spots, grind them down; if there are low spots (more than 1/4 inch in a 10-foot span), use a self-leveling compound to fix them. Finally, sweep the floor completely clean—even a small piece of dust or gravel under a plank can create a bump that will feel uneven underfoot.
- For plywood subfloors: Plywood is more forgiving, but it still needs to be flat. Check for any loose boards, and screw them down tight if they’re wobbly. If there are gaps between planks, fill them with wood filler. You also want to make sure the plywood is at least 5/8 inch thick—if it’s thinner, add a layer of 1/2 inch plywood on top to create a sturdy base.
- One more thing: Remove any baseboards, trim, or door casings from the walls. You’ll need to slide your teak planks under these, and you can always reinstall them later.
Step 2: Choose Your Installation Method (Nail-Down vs. Glue-Down vs. Floating)
Teak can be installed three ways, and the method you choose depends on your subfloor and your skill level. As a supplier, we recommend nail-down for solid teak planks (it’s the most durable), and glue-down for engineered teak, but I’ll break down all three so you can pick what works for you.
Nail-Down Method (Best for Solid Teak)
This is the most traditional method, and it’s what we use for professional installations. It’s also the best option for durability, since your planks are secured directly to the subfloor. Here’s how to do it:
- You’ll need a flooring nailer (also called a cleat nailer) — this is a specialized tool that drives L-shaped cleats through the side of each plank, at a 45-degree angle, so the next plank locks into it. If you don’t own a nailer, most home improvement stores rent them for a reasonable price.
- First, layout a starting line. Your first row of planks needs to be perfectly straight, so use a chalk line to mark a line 1/2 inch away from the wall (that gap is for expansion, so your floor doesn’t buckle). Place a spacer (a plastic or wooden block) between the first plank and the wall to maintain this gap.
- Start installing the first row: Run a small bead of construction adhesive along the subfloor under the first plank to add extra stability. Use your nailer to drive cleats into the side of the plank, about 1 inch from the ends and every 6 to 8 inches along the length. Make sure the cleats are driven deep enough so they’re not sticking out—you don’t want them to scratch the next row of planks.
- For the next rows: Place the end of the new plank against the end of the previous row, and use a rubber mallet to tap it tight (never use a steel mallet, which can dent the wood). Stagger the ends of the planks by at least 6 inches—if every plank ends at the same spot, you’ll have a weak spot in your floor that can crack over time.
- When you get to the last row, you might need to cut the planks to fit. Use a circular saw with a fine-tooth blade (at least 60 teeth) to cut the plank, and leave a 1/2 inch gap against the wall just like the first row.
Glue-Down Method (Best for Engineered Teak)
Engineered teak has a plywood base, so it’s more flexible, and glue-down creates a seamless, stable floor. This is also a good option if your subfloor is concrete. Here’s how:
- Clean your subfloor completely, then apply a high-quality hardwood floor adhesive (look for one rated for hardwood and concrete). Spread the adhesive in small sections, about 3 to 4 square feet at a time, so it doesn’t dry before you lay the planks.
- Place the first plank along your chalk line, pressing it firmly into the adhesive. Wipe up any excess adhesive right away with a damp cloth—once it dries, it’s nearly impossible to remove.
- Continue laying planks, staggering ends, and keeping the 1/2 inch gap along the walls. Use a heavy roller (50 pounds or more) to roll the floor after every few rows to ensure the planks are bonded tightly to the subfloor.
- For the last row, use a flooring jack to fit the planks into place (they’ll be too tight to tap with a mallet without damaging them).
Floating Method (Easiest for DIYers)
This is the most beginner-friendly method, and it works for both solid and engineered teak. The planks lock together with tongue-and-groove edges, and they “float” on a underlayment pad laid over the subfloor. No nails or glue needed. Here’s how:
- Start with the underlayment: Lay a 6-mil thick plastic sheet over the subfloor, overlapping the edges by 6 inches and taping them down with duct tape. Then lay the foam underlayment pad, staggering the seams so they don’t line up with the plastic tape. This pad creates a cushion and helps reduce noise.
- Lay the first row along your chalk line, spacing 1/2 inch from the wall. The tongue side of the plank should face the wall (or the next plank will lock into the groove side).
- For the next rows: Align the groove of the new plank with the tongue of the previous plank, and angle it at 15 to 20 degrees to lock it in. Tap it gently with a rubber mallet until it’s tight. Stagger ends just like with the other methods.
- When you get to the last row, you’ll need to cut the planks lengthwise. Lay the plank on top of the last full row, mark where it needs to fit, and use a circular saw or a jigsaw to cut it.
Step 3: Troubleshooting Common DIY Mistakes
After guiding so many DIYers, I’ve seen the same mistakes over and over. Here’s how to avoid them:
- Gaps between planks: This is usually from not acclimating your planks, or tapping planks too hard with a mallet. If you end up with gaps after installation, you can fill them with wood filler that matches your teak’s color. But if the gaps are larger than 1/8 inch, you probably didn’t acclimate enough—next time, wait longer.
- Uneven floors: This comes from not leveling your subfloor. Before you start, spend the extra time to grind down high spots and fill low spots—this step saves you from having to sand the entire floor later, which is a huge hassle.
- Buckling: Buckling happens when planks swell because of excess moisture, usually from a damp subfloor or poor acclimation. If you notice buckling, you’ll need to remove the planks, dry the subfloor completely, and re-acclimate the planks before reinstalling them.
- Scratches on planks: This is easy to avoid—when driving nails or cleats, make sure they’re not sticking out. When cutting planks, use a fine-tooth blade to prevent splintering, especially on teak’s smooth surface.
Step 4: Finishing Touches That Will Make Your Floor Last
Once the planks are installed, you’re almost done, but there are a few final steps to make your teak floor look perfect and last for 50+ years.
First, let the floor settle for 24 hours. Don’t walk on it during this time—this gives any adhesive or nails time to set.
Next, install the baseboards and trim. Cut your new baseboards to fit the walls, and use a nail gun to attach them, covering the 1/2 inch expansion gap along the wall. If you want a seamless look, you can also install quarter-round molding along the bottom of the baseboards, but that’s optional.
Finally, sand and finish the floor. Wait at least 2 weeks after installation to finish your teak floor—this gives the planks time to acclimate fully. Teak has natural oils, so you can skip the sanding if you want to keep its natural look, but if you want a smoother surface, use a fine-grit sandpaper (120 grit) to lightly buff the floor. Then apply a teak-specific wood finish—we recommend a penetrating oil finish, which brings out teak’s rich color without making it look glossy. Avoid polyurethane, which can seal in the natural oils and cause the floor to crack over time. If you’re not sure which finish to use, our team can send you a sample of our finishes, along with a small teak plank to test it on.
Why Go Through All This?
I know, it’s a lot of steps, but a teak floor is one of the best investments you can make in your home. It adds value, looks better with age (teak develops a beautiful silver patina over time), and is far more durable than carpet or vinyl. And if you do it yourself, you’ll save 50% to 75% on installation costs—thousands of dollars that you can put toward furniture, decor, or even more teak accents for your home.
