DIY Tips for Installing Timber Floorboards in Your Sydney Home

Laying timber floorboards can be an exciting and rewarding DIY project for homeowners in Sydney, NSW, especially for those looking to add a natural and stylish touch to their interiors. While solid timber flooring is often best left to professionals due to its complexity, there are affordable and easier-to-install floating floor systems available that even capable DIYers can take on.

In this guide, we at Sydney Budget Kitchens will walk you through key tips and steps to help you successfully install timber flooring in your home. By following these guidelines and understanding the basics, you’ll be well on your way to transforming your space with beautiful, durable flooring.

1. Understand Your Timber Flooring Options

Before you start, it's important to understand the different types of timber flooring available and which one suits your home and skill level. The two primary categories are solid timber and floating floors.

• Solid Timber Flooring: This traditional option is made from 100% hardwood, making it long-lasting and extremely durable. However, its installation requires precision and expertise, which is why we often recommend leaving this to professionals. The process involves nailing, sanding, and finishing, which can be time-consuming and expensive.

• Floating Floor Systems: These are a more affordable and DIY-friendly option, available in both solid and laminated timber variations. Floating floors are not nailed or glued to the subfloor; instead, they “float” above it. They can be installed over existing flooring, making them an attractive solution for budget-conscious homeowners.

The floating floor system is easier to install, and with proper preparation and the right materials, you can achieve a professional-looking result without the hefty price tag.

2. Prepare the Existing Floor

Preparation is key when laying timber flooring, especially for a floating floor system. A poor foundation can lead to uneven surfaces, squeaks, or even damage to the floorboards over time. Here’s what you need to do:

• Level the Floor: The first step is to ensure that your existing floor is completely level. If there are high spots, grind them down. If there are low spots, fill them with an appropriate filler. An uneven base can cause your floating floorboards to buckle or wear unevenly.

• Ensure the Floor is Clean and Dry: Any dirt, dust, or moisture can affect the adhesion of the boards or the long-term health of your flooring. If you're installing over a concrete subfloor, ensure it has fully dried before beginning your installation. Fresh concrete can take months to completely cure, so check its moisture content using a concrete moisture meter.

Proper preparation of your subfloor will extend the life of your timber floors and prevent any future issues.

3. Acclimatise Your Timber

Timber is a hygroscopic material, meaning it absorbs and releases moisture depending on the surrounding environment. Because of this, timber expands and contracts with changes in humidity. This natural movement is something you need to consider before installing your floorboards.

Acclimatisation: Before installing timber floorboards, store them in the room where they will be laid for at least one to two weeks. This will allow the timber to acclimatise to the temperature and humidity levels of the space. Skipping this step could result in gaps or warping once the boards are laid and exposed to the room’s conditions.

By allowing the wood to adjust to its environment, you can prevent costly adjustments or repairs in the future.

4. Choose Pre-Finished or Unfinished Boards

When it comes to timber flooring, you have the option of selecting pre-finished or unfinished boards. Both have their advantages, depending on your time constraints and desired finish.

• Pre-Finished Boards: These boards come already sanded, stained, and sealed, meaning they are ready to install straight out of the box. Pre-finished boards can save you considerable time and effort, making them a popular choice for DIYers.

• Unfinished Boards: Unfinished boards need to be sanded and sealed after installation. While this adds more work to your project, it also gives you greater flexibility in terms of finish and colour. If you have a specific stain or gloss level in mind, unfinished boards might be the better option.

• For those new to DIY timber flooring, we recommend pre-finished boards as they offer convenience without sacrificing the quality of the final result.

5. Understand Tongue and Groove Profiling

Many timber floorboards, especially those in floating floor systems, come with tongue and groove profiling. This system makes installation easier and helps secure the boards in place.

Tongue and Groove System: One side of each board has a protruding “tongue” that fits into a corresponding “groove” on the next board. This method ensures a snug fit and prevents the boards from shifting over time. The tongue and groove system is a tried-and-true method that results in a solid, long-lasting floor.

Some products even come with a special "secret nailing" system, where nails are driven through the tongue and into the subfloor, hiding the nails from view. This creates a smooth, uninterrupted surface that adds to the aesthetic appeal.

6. Account for Expansion and Shrinkage

As we mentioned earlier, timber naturally expands and contracts with changes in humidity. To prevent issues like warping or buckling, it’s important to account for this movement during installation.

• Leave Expansion Gaps: When laying your floorboards, leave a small gap between the boards and the walls. This space will allow the timber to expand without pushing against the walls or other surfaces. Expansion gaps can be concealed with skirting boards or beading, preserving the aesthetic of the room while allowing the timber to move as needed.

• Avoid Laying Floorboards Between Rooms: Don’t lay a continuous row of floorboards from one room to another. This can restrict the natural movement of the boards and lead to buckling. Instead, use transition strips or expansion joints to separate the flooring between rooms. These joints provide flexibility and protect your floors from damage.

7. Measure Correctly and Allow for Wastage

Accurate measurements are essential when ordering your timber flooring. Understanding the basic units of measurement will help you ensure you purchase enough material for your project.

• Square Metres and Lineal Metres: Measure the length and width of your room (in metres) to calculate the area in square metres. To determine the number of lineal metres of floorboards required, divide the area by the width of the boards you have chosen.

• Allow for Wastage: Always order extra material to account for wastage. This wastage typically occurs due to cuts, mistakes, or imperfections in the timber’s pattern or structure. A 10% allowance is a safe estimate to ensure you don’t run short of boards during installation.

By taking the time to measure accurately and account for wastage, you’ll avoid delays and frustrations once you start the project.

8. Tools and Techniques for Installation

Having the right tools is crucial to a successful DIY timber floor installation. You’ll need:

• A rubber mallet and tapping block to gently tap the boards into place without damaging them.
• A saw for cutting boards to size.
• A measuring tape and square to ensure precision with your cuts and board placement.

Once your boards are ready to go:

• Lay the boards lengthways with the cut edge against the longest wall of the room.
• Use the rubber mallet and tapping block to tap the panels into place, ensuring a tight fit.
• Ensure the first row is perfectly straight as this will affect the alignment of the rest of the flooring.

After the floor is installed, inspect the seams and make sure everything is snug and secure. Depending on the product you choose, you may need to seal the boards or apply a finish to protect the wood from wear.
