Timber floorboards offer a classic, natural look that suits both traditional and modern interiors. Whether you're renovating a period property or adding warmth to a contemporary room, installing timber flooring yourself can be a rewarding project, provided it’s done properly. 

Step 1: Choose the Right Floorboards 

Before starting, select the appropriate type of timber for your space. Softwood floorboards are ideal for subflooring, lofts, or rooms where a more natural, rustic finish is preferred. For high-traffic areas, hardwood floorboards are recommended for durability. 

Ensure the boards are acclimatised by storing them flat in the room where they'll be laid for at least 48 hours. This helps minimise movement after installation. 

 

Step 2: Prepare the Subfloor 

A clean, dry, and level subfloor is essential. Whether you're installing concrete, plywood, or existing boards, make sure the surface is sound and free of any loose debris. Use a moisture barrier if installing on concrete and secure any creaky or uneven boards if going over timber. 

 

Step 3: Plan Your Layout 

Plan the direction of the boards, typically, they should run lengthways in the longest direction of the room or perpendicular to floor joists for added strength. Dry lay a few rows to visualise spacing and how boards will fit around corners, doors, and skirting. 

Use floorboard spacers to allow for an expansion gap (usually 10–15mm) around the perimeter of the room. This prevents warping as the timber expands and contracts with changes in humidity. 

 

Step 4: Lay the Floorboards 

Start laying the boards from one corner of the room, tongue facing out. Secure the boards either by secret nailing (into the tongue) or top nailing, depending on the style of board and your preference. 

  • For secret nailing, use a flooring nailer for quick, hidden results. 
  • For top nailing, drill pilot holes to avoid splitting and use decorative nails for a rustic finish. 

Ensure each board is snug against the next before securing it. Use a tapping block and mallet if necessary to keep lines tight and even. 

 

Step 5: Sand and Finish 

Once all boards are in place, sand the floor to create a smooth, even surface. If you're using pre-sanded boards, this step may be minimal. Apply your chosen finish, oil, stain, or varnish, to protect the timber and enhance its natural grain. 

Allow the finish to dry fully before replacing furniture or walking on the floor.
