Identifying Floor Gaps
Timber floors can have gaps due to several reasons. Wood shrinkage is a common cause. It happens when wood loses moisture. Temperature changes can also cause gaps. Wood expands in heat and contracts in cold. Improper installation might lead to gaps too. If boards are not fitted well, gaps form. Ageing of the timber can widen gaps over time. Humidity levels play a role as well. Low humidity can make wood dry out, creating gaps.
Check the gap size to assess severity. Small gaps are less than 3mm. These are minor. Medium gaps range from 3mm to 6mm. These need attention. Large gaps exceed 6mm. These are severe and need fixing soon. Measure gaps with a ruler for accuracy. Note any changes in gap size over time. Bigger gaps might mean a problem. Observe floor movement. Too much movement can widen gaps. Serious gaps may need professional help.

Preparation Before Repair
Start by sweeping the floor. Remove any dust and dirt. Use a vacuum for stubborn dirt. Mop the floor with warm water. Let it dry completely. A clean floor shows gaps better. It helps in better repair work.
Collect the tools before starting. Get a putty knife and wood filler. Sandpaper is also needed. You might need a damp cloth. A vacuum cleaner helps too. Keep all tools near you. This saves time and effort.
Choosing The Right Filler
Many types of wood fillers are available. Epoxy fillers are strong and durable. Acrylic fillers dry fast and are easy to use. Latex fillers are flexible and can handle movement. Each type has its own benefits. Choose the one that suits your needs best.
Flexible fillers move with the wood. They are great for timber floors. Silicone-based fillers are very flexible. Polyurethane fillers last a long time. These fillers prevent cracks from forming. They help keep your floor looking nice.
Natural fillers are safe for the environment. Sawdust mixed with glue makes a simple filler. Beeswax is another natural option. It fills gaps and adds shine. Natural solutions can be a great choice for eco-friendly homes.

Step-by-step Filling Process
Choose a wood filler that matches the color of your timber floor. Clean the gaps with a vacuum. Make sure there is no dirt. Apply the filler using a putty knife. Press it firmly into the gaps. Wipe off any excess filler before it dries. Allow the filler to dry completely. This may take a few hours.
Once the filler is dry, sand the area gently. Use fine-grit sandpaper to smooth the surface. Be careful not to sand too hard. You don’t want to damage the wood. After sanding, wipe the area clean. Apply a suitable floor finish. Choose between oil or varnish. Apply a thin layer to protect the wood.
Inspect the floor for any rough spots. Sand again if needed. Ensure the floor is even and smooth. Walk over it to check for bumps. Feel the surface with your hands. It should be smooth and soft. If you find uneven areas, repeat the process. Fill, sand, and finish again. This guarantees a nice, smooth floor.
Preventing Future Gaps
Keeping the right humidity levels in your home is crucial. Timber floors need a balanced environment. Use a humidifier in dry months. A dehumidifier helps in wet seasons. Check your home’s humidity regularly. Aim for 40% to 60% levels. This keeps your floors happy.

Maintaining Timber Floors
