-If your hardwood floors aren't fixed to the subfloor, you can slide the boards back into place. -You can use a filler for minor gaps and separations. -You can use wooden pegs in the perimeter of the room to help keep the boards in place, though this is for hardwood floors that aren't connected to the subfloor.
Separating floor planks may occur due to various factors such as humidity, temperature changes, improper installation, or subfloor issues. Addressing these issues ensures structural integrity, prevents further damage, and maintains the aesthetics of your flooring.
You don't want to fill gaps. Wood expands and contracts thus gaps come and go. It's part of using a natural material such as wood.
Wood floors continually expand and contract with changes in temperature and humidity of the jobsite/environment. In the winter, with heat being turned up for warmth, the moisture level will decrease. In turn, the wood floor boards will also get drier and shrink, and as they do, they will pull away from each other.
Temperature and Moisture: wood is a natural and organic material, it can expand and contract with moisture and temperature changes. When these become extreme, it can cause wood flooring separation. You wouldn't notice the expansions and contractions usually unless the floorboards are very tight together.
Where do I start to stop the cold air coming in through my wooden floorboards? The best solution is to insulate underneath your floor with a Polyester Underfloor Insulation and/or fill any cracks or gaps with UltraClear. This is where and how to start: Find out if you have gaps between your floorboards.
Our recommendation for the best wood filler is the Toupret Extrem Wood Filler, also from Toupret's filler range, as it provides a comprehensive repair system for interior and exterior wood, plus it is designed to repair both large and small gaps, cracks and holes.
If the planks are too loose, use wood glue or finishing nails to secure them back in place. In extreme cases, a professional re-sanding and refinishing might be needed. For minor creaks, a quick DIY fix is placing shims or screws from underneath to tighten the boards.
Apart from moisture and temperature fluctuations, wood floor boards can separate and develop gaps if the flooring hasn't been properly acclimatised prior to installation or if an insufficient expansion gap has been left around the room.
To reinstall salvaged and new planks, use a brush, roller or trowel to apply a thin, even layer of adhesive on the underside of each affected floor panel. When your adhesive is ready, lay down the floorboards. Secure the planks by pressing down firmly on the center, edges and corners with a clean, dry roller.
If the gap is smaller than 1⁄2 in (1.3 cm), fill it with silicone caulk. Fill gaps larger than 1⁄2 in (1.3 cm) with a few pieces of wood, foam insulation, or spray insulation. Nail a baseboard or quarter round over the filled gap, then caulk around the baseboard.
Clamp and wood glue on the piece with the split that runs with the grain. Wood glue and a screw or nail on the break at the 90. Drill a hole before running in a screw so you don't split it again.
Extreme temperature fluctuations can cause the vinyl planks to expand and contract, leading to separation. Placing heavy furniture or dragging sharp objects can result in separation. Wear and tear over time can cause vinyl plank flooring to separate.
For unfinished floors, you can use a mixture of fine sawdust and polyurethane to fill small gaps: Collect fine sawdust from sanding the same type of wood as the flooring.
If using wood filler or putty, apply it to the gap with a putty knife, ensuring it's filled. For wood strips, apply wood glue into the gap, insert the strip, and use a hammer to tap it into place gently. If using wood dust and resin, apply the paste to the gaps with a putty knife, ensuring each gap is filled.
If you have sawdust from the same type of wood, you can mix it with wood glue to create a paste-like consistency. Apply the mixture to the damaged area and let it dry. Once dry, sand it down to create a smooth surface that blends in with the surrounding wood.
You shouldn't use wood filler on wood that is already finished or on wood that is to be used in an exterior setting. Wood filler shrinks and hardens and will fail in the event of expansion and contraction, which is much more likely in exterior uses than interior uses.
You can use a humidifier to add moisture to the air, especially during the winter months when the air tends to be drier. Humidifiers help prevent the wood from drying out, and can also improve your overall comfort.
Make Use of Area Rugs
If your wooden floor isn't suitable for use with underfloor heating, there are other options. Adding area rugs to the floor can greatly enhance its warmth. This is also a much more affordable tip you can follow if you're on a budget. Try to add the rugs to the coldest spots of the floor.
