Hi, We finished laying our Charcoal Grey (looks like black) laminate flooring in our kitchen and all the skirtings and furniture have been put back, now we find we have a 6 inch scratch. It is only a light scratch, not deep but it is on a piece of flooring in front of the washing machine which makes it noticable. Any suggestions please on how I can disguise this? I think black felt pen would maybe be too black ?
