9 Easy Steps on How to Lay Timber Floor on Concrete
Step 1: Prepare the Concrete Surface
Before laying your timber floor, preparing the concrete surface properly is crucial to ensure durability and a smooth finish. Begin by thoroughly cleaning the concrete base to remove any debris, dust, or grease that may hinder the bonding of the adhesive or underlay.
Use a broom, vacuum, or a damp cloth to achieve an immaculate surface. Next, inspect the concrete for any cracks, holes, or uneven areas.
These imperfections can affect the stability of your timber floor, so it is essential to fill in cracks or holes with a suitable concrete patching compound. Once the repairs have dried, check the surface for levelness using a spirit level. If there are high or low spots, use a grinder to smooth out elevated areas or a self-leveling compound to address any dips. Finally, ensure the concrete surface is completely dry before moving on to the next step, as moisture can damage the timber or weaken the adhesive.
Step 2: Acclimate the Timber Flooring
Before installation, it is essential to allow the timber flooring to acclimate to the environment where it will be installed. After laying the flooring, this step helps prevent warping, expansion, or contraction. Place the timber planks in the room for at least 48-72 hours to adjust to the temperature and humidity levels. Ensure the planks are laid flat and slightly apart for proper air circulation. This process ensures that the wood adapts to its new environment, helping maintain the stability and longevity of your flooring.
Step 3: Lay the Underlay
Install a suitable underlay over the prepared concrete surface. The underlay is a moisture barrier and provides cushioning for the timber flooring. Roll out the underlay, ensuring it covers the entire surface area without overlapping. Trim any excess material along the edges for a clean finish. Secure the underlay with adhesive tape if needed, and verify that it is smooth and free of wrinkles or gaps. This step creates an even base and protects your flooring from moisture-related damage.
Step 4: Begin Laying the Timber Flooring
Start laying the timber planks along the most prolonged and straightest wall in the room, allowing for an expansion gap of at least 10-12mm between the planks and the wall. Use spacers to maintain this gap consistently. Fit the planks together by aligning the tongue and groove edges, ensuring a snug and secure
connection. Use a tapping block and mallet to gently tap the planks into place without causing damage. Continue laying the planks row by row, staggering the joints by at least 150mm to create a strong and visually appealing pattern. Periodically check that the rows remain aligned and the seams are tight.
Step 5: Cutting and Fitting Edge Planks
When you reach the room’s edges or encounter obstacles such as doorways or pipes, measure and cut the timber planks to fit these spaces precisely. Use a saw to make accurate cuts, ensuring the plank edges remain clean and straight. For irregular shapes or tight spots, a jigsaw may be more effective. After cutting, fit the planks into place, maintaining the expansion gap of 10-12mm around the perimeter. Double-check that the cut pieces align seamlessly with adjacent planks for a polished finish.
Step 6: Securing the Expansion Gap
Once all planks are laid and fitted, confirm that the perimeter’s 10-12mm expansion gap is clear and consistent. This gap allows the flooring to expand and contract with changes in temperature and humidity, preventing damage or warping—place spacers along the edges to maintain this gap until the skirting boards or trim are installed. Regularly inspect the gap around the room to ensure uniformity before proceeding.
Step 7: Installing Skirting Boards or Trim
With the flooring entirely laid and the expansion gap secured, it’s time to install the skirting boards or trim to complete the finish. Remove the spacers carefully, ensuring the gap is maintained. Position the skirting boards
or trim over the edges of the flooring, covering the expansion gap without applying pressure on the floor itself. Secure the skirting boards or trim to the wall using nails, screws, or adhesive, depending on your preference and materials. This step not only enhances the room’s aesthetic appeal but also protects the expansion gap and ensures a clean, professional appearance.
Step 8: Cleaning and Final Inspection
Once the skirting boards or trim are installed, it’s essential to thoroughly clean the floor to remove any dust, debris, or adhesive residue left from the installation process.
Use a soft-bristled broom or a vacuum cleaner with a suitable attachment to ensure no scratches occur on the new flooring. Next, a final inspection of the entire installation will be conducted. Check for loose boards, uneven gaps, or improperly secured trim, and make adjustments as necessary. This step ensures the floor is not only visually appealing but also structurally sound ready for use.
Step 9: Enjoy Your New Floor
With the installation and final inspection completed, your new flooring is ready to be enjoyed. Take a moment to admire your work and the transformation it brings to the space. Proper maintenance, such as regular cleaning and using protective pads under furniture, will help preserve the floor’s appearance and durability for years. Congratulations on completing your flooring project!
Following these 10 easy steps, you can successfully lay timber flooring on a concrete surface.
5 Things You Should Avoid
- Skipping Moisture Testing: Failing to test the concrete for moisture levels can lead to disastrous results. Excess moisture can cause the timber to swell, warp, or even deteriorate. Ensure the concrete is dry and meets the required moisture standards before installation.
- Not Preparing the Surface Properly: Uneven or dirty concrete surfaces can cause issues during and after installation. Neglecting to clean, level, and smooth the surface can result in an unstable or poorly adhered timber floor.
- Ignoring an Underlay: Installing timber directly onto concrete without a proper underlay is a common mistake. A high-quality underlay acts as a moisture barrier and provides cushioning, reducing the chances of damage and improving comfort underfoot.
- Using the Wrong Adhesive: Choosing adhesives incompatible with the timber or the concrete can lead to weak bonding. Always use adhesives designed explicitly for timber flooring to ensure long-lasting results.
- Rushing the Acclimatization Process: Timber needs time to acclimatize to the environment where it will be installed. Skipping this step can lead to issues like expansion or contraction after installation. Allow the timber to adjust to the room’s temperature and humidity for at least a few days before starting.
By avoiding these common mistakes, you can ensure a successful and long-lasting timber flooring installation.
