Installing a timber floor over concrete can transform the look and feel of your home, creating a warm and inviting atmosphere. With careful preparation and the right techniques, you can achieve a professional-looking finish that will last for years to come. As you embark on this project, remember that patience and attention to detail are key.
Before beginning the installation, ensure that the concrete subfloor is level, dry, and free from any debris. Any unevenness or moisture can compromise the stability and durability of your new floor. If necessary, use a self-leveling compound to smooth out any imperfections and allow the concrete to dry thoroughly. Once the subfloor is prepared, it’s time to lay down an underlayment. This moisture barrier will protect your timber floor from dampness and provide additional insulation and soundproofing.
Now you’re ready to start laying the timber planks. Begin by establishing a straight starting line along one wall of the room. Use spacers to ensure even gaps between the planks and install the first row perpendicular to the longest wall. As you progress, check each plank for levelness and adjust the spacers as needed. Stagger the joints between the planks to create a more durable and visually appealing floor. Remember to leave a small expansion gap around the perimeter of the room to allow for natural movement of the timber as it expands and contracts with changes in temperature and humidity.
Preparing the Concrete Surface
1. **Remove existing flooring and debris.** Remove any existing flooring, baseboards, and other obstacles that may interfere with the installation of the timber floor. Sweep and vacuum the concrete surface to remove any dust or debris.
2. **Level and smooth the concrete surface.** The concrete surface must be level and smooth to ensure a proper installation of the timber floor. Grind or level any uneven sections using a concrete grinder or leveler. If the concrete surface is rough, it may be necessary to apply a self-leveling compound to fill in any voids or imperfections.

3. **Inspect the concrete surface for cracks or damage.** Examine the concrete surface for any cracks or damage, such as holes or missing sections. Repair any cracks or damage using an appropriate flooring patch or repair material. Apply the repair material according to the manufacturer’s instructions and allow it to cure completely.
4. **Clean the concrete surface.** The concrete surface should be clean and free of any oils, grease, or dirt that may impede the adhesive bond. Mop the surface with a diluted cleaning solution and allow it to dry completely before proceeding with the installation.
Cutting and Fitting the Floorboards
Once you have the underlayment down, it’s time to start laying the floorboards. Begin by measuring and cutting the first board to fit against the wall. Use a circular saw to make precise cuts, and be sure to leave a small gap of about 10mm between the board and the wall to allow for expansion.
To fit the next board, simply slide the tongue of the board into the groove of the previous board. Use a tapping block and a hammer to gently tap the board into place. Continue this process until you reach the end of the row.
When you need to cut a board to fit around obstacles, such as pipes or door frames, use a jigsaw to make the cut. Be sure to measure carefully and make a clean cut to ensure a good fit.
Once you have laid the first row of floorboards, continue laying the remaining rows in the same way. Be sure to stagger the joints between the rows to create a more durable floor. You may also need to use spacers to ensure that the boards are evenly spaced apart.
Here is a table summarizing the steps for cutting and fitting the floorboards:

Maintaining Your Timber Floor
Timber flooring is a beautiful and durable addition to any home, but it requires regular maintenance to keep it looking its best. Here are some tips on how to clean and care for your timber floor:
Sweep or vacuum regularly
To remove dust and dirt, sweep or vacuum your timber floor regularly. Be sure to use a soft brush attachment on your vacuum cleaner to avoid scratching the floor.
Mop occasionally
For a deeper clean, mop your timber floor occasionally with a damp mop. Use a mild detergent and water solution, and avoid using harsh chemicals or abrasive cleaners.
Remove spills immediately
If you spill something on your timber floor, clean it up immediately. Use a damp cloth to wipe up the spill, and then dry the area with a clean cloth.
Use floor protectors
To protect your timber floor from scratches and dents, use floor protectors under furniture and appliances. You can also place rugs in high-traffic areas.
Avoid wearing shoes with hard soles
Wearing shoes with hard soles can damage your timber floor. Instead, opt for shoes with soft soles, such as slippers or sneakers.
Keep your floor dry
Water can damage your timber floor, so it’s important to keep it dry. Avoid spilling water on your floor, and mop up any spills immediately.
Avoid placing heavy objects on your floor
Heavy objects can put excessive pressure on your timber floor, which can cause it to crack or buckle. Avoid placing heavy objects, such as furniture or appliances, on your floor.
Quarterly Maintenance
Every three months, apply a fresh coat of polyurethane or a penetrating oil finish to protect the timber and maintain its appearance. This will help to protect your floor from wear and tear, and will keep it looking its best for years to come. If you’re not comfortable doing this yourself, you can hire a professional to do it for you.

Troubleshooting Common Issues
Uneven Surface
Uneven concrete surfaces can lead to an uneven timber floor. To address this issue, use a self-leveling concrete mix to smooth out the base before laying the timber.
Moisture Issues
Moisture from the concrete can damage the timber flooring. To prevent this, install a vapor barrier between the concrete and the timber, and allow the concrete to dry thoroughly before installation.
Squeaking Noises
Squeaking noises can occur when the timber flooring is not properly secured to the concrete. Ensure that the joists are spaced at regular intervals and securely fastened to the concrete using appropriate fasteners.
Warping and Buckling
Excessive moisture or temperature changes can cause timber flooring to warp or buckle. To avoid this, maintain a consistent indoor climate, and use a moisture meter to ensure that the concrete is sufficiently dry before installing the timber.
Expansion and Contraction
Timber flooring naturally expands and contracts with changes in temperature and humidity. To accommodate this, leave an expansion gap around the perimeter of the room and install expansion joints to prevent buckling or damage.
Cracking and Splitting
Cracking and splitting can occur due to excessive stress or improper installation. Ensure that the timber planks are adequately supported by joists and that the nails or screws are driven at the correct angle to avoid splitting.
Loose or Broken Planks
Loose or broken planks can be caused by poor installation or damage. Inspect the planks for any damage and replace or repair them as necessary. Ensure that the planks are securely fastened to the joists using appropriate fasteners.
Subfloor Preparation
Proper subfloor preparation is crucial for a successful timber floor installation. Ensure that the concrete surface is clean, smooth, and free of any debris or uneven areas.
