Starting at one end with the iron on a hot setting run the iron up and down the grain several times until the veneer is bonded, then using a block rub the veneer with some pressure to ensure a good bond.
It might be worth having a little practice before moving on to the main project.
May vary from picture shown.
Please note this is a raw untreated wood veneer so the final colour will be determined after a finish has been applied.
Please note that these stringers are made from natural real wood Oak. As such, the veneer production process (and timber length) limits the length that can be produced without joins. Therefore these stringers (as with all others) will have finger joints at varying points along their length. These are designed to iron down without a problem. They run with the grain to minimise their visibility. The stringer(s) should be unpacked as soon as possible (one week maximum) after receipt to ease tension on the joints.
