Place the last row of wood flooring boards precisely on top of the last but one row. Use an off cut with the tongue side facing the wall together with an expansion gap wedge. Draw a pencil line on the last flooring board by tracing the exact contour of the wall onto the wood by manoeuvring the off cut along the wall.
Use a jigsaw to saw along the board on the line and ease the board into place using a screwdriver, lever or small crowbar to lever the last board into the T&G joint and add the expansion gap wedges against the wall.
