Benefits of Solid Timber Flooring
Before jumping into the installation process, it’s essential to understand why solid timber flooring is a popular choice. Here are some key benefits:
- Durability: Solid timber flooring is built to last, often outliving other flooring options when properly maintained.
- Timeless Appeal: Timber has a classic look that never goes out of style and can suit various decor themes.
- Improved Property Value: Homes with solid timber flooring typically have a higher resale value.
- Natural Insulation: Timber helps regulate indoor temperature, providing a cozy, comfortable environment.
Whether you’re upgrading your current space or building a new one, solid timber flooring installation can be a wise investment. Let’s explore how to install solid timber flooring step-by-step.
Tools and Materials Needed for Solid Timber Flooring Installation
Before starting, gather these essential tools and materials:
- Timber flooring (ensure you have enough to cover your space with extra for any errors)
- Flooring adhesive
- Moisture barrier (if installing over concrete)
- Underlay
- Nail gun or drill
- Tape measure
- Saw
- Rubber mallet
- Chalk line
Having these tools on hand will make the solid timber flooring installation process smoother and more efficient.
Step 1: Prepare the Subfloor
A successful solid timber flooring installation begins with a solid foundation. Preparing the subfloor is crucial for durability and performance. Here’s how to prepare your subfloor for installation:
- Clean the Subfloor: Remove any dust, dirt, or debris from the area.
- Level the Floor: Ensure the floor is level. If it’s not, use a leveling compound to fill any dips or gaps.
- Check Moisture Levels: Solid timber is sensitive to moisture, so check the subfloor’s moisture levels, especially if installing over concrete. Use a moisture meter, and if the subfloor is too damp, install a moisture barrier.
A well-prepared subfloor provides the foundation for a long-lasting, durable installation, so don’t skip this step!
Step 2: Acclimate the Timber
Timber needs time to adjust to the room’s humidity and temperature before installation. This process, called acclimation, helps reduce the risk of warping or gaps post-installation. Here’s how to acclimate your timber flooring:
- Lay the Timber in the Room: Place the boards in the room where they’ll be installed for at least 3-5 days.
- Ensure Proper Ventilation: Allow air to circulate freely around the boards during acclimation.
- Check Manufacturer Recommendations: Some timber types may require longer acclimation times, so always follow the manufacturer’s guidelines.
Step 3: Lay the Underlay and Moisture Barrier
If you’re installing over a concrete subfloor, a moisture barrier is essential. This layer protects the timber from moisture seeping up from the ground.
- Install the Moisture Barrier: Lay it across the subfloor, overlapping edges by 2-3 inches to prevent moisture from getting through.
- Add the Underlay: Place the underlay on top of the moisture barrier. This underlay provides sound insulation and comfort underfoot.
With this layer in place, you’re now ready to start laying the timber planks.
Step 4: Install the Timber Planks
Now comes the exciting part: installing the timber planks. This stage requires precision and patience.
- Start Along a Straight Wall: Begin by laying the first row along the longest, straightest wall.
- Use Spacers for Expansion Gaps: Place spacers along the wall to allow for a 10-15mm expansion gap. Timber expands and contracts with changes in humidity, so this gap is essential.
- Glue or Nail the Planks: Depending on your preference, either glue the planks directly to the subfloor or use nails. Some installations require both for extra stability.
- Stagger the Planks: For a more natural look, stagger the end joints of each row.
- Continue Laying Rows: Work row by row, ensuring that the boards are tightly joined using a rubber mallet if needed.

Step 5: Sand and Finish (if necessary)
If you’ve installed unfinished timber, you’ll need to sand and finish the floor. Sanding smoothens the surface, while finishing provides protection and enhances the timber’s natural beauty.
- Sand the Surface: Start with coarse-grit sandpaper, then gradually use finer grits for a polished look.
- Apply the Finish: Choose a finish that suits your aesthetic—oil-based, water-based, or polyurethane. Apply according to the manufacturer’s instructions.
For pre-finished timber, you can skip this step, as the planks come with a durable surface layer.
Tips for Maintaining Solid Timber Flooring
Once your solid timber flooring installation is complete, proper maintenance is essential to preserve its beauty and longevity. Here are some tips for maintaining your timber floors:
- Use Furniture Pads: Place pads under furniture legs to prevent scratches.
- Sweep Regularly: Dust and dirt can damage the surface, so sweep or vacuum often.
- Use a Damp Mop: Avoid soaking the floor with water; a slightly damp mop is ideal for cleaning.
- Refinish When Needed: Timber floors can be sanded and refinished to restore their original luster.
