Liberon Retouch Crayons can be used to fill scratches, nail holes, worm holes in furniture and other woodwork. Traditional recipe based on carnauba and beeswax, expand and contract with the wood. Do not shrink or drop out. Rub the crayon across the scratch until it is filled, allow to harden then buff off the excess with a cotton cloth or steel wool. Retouch crayons may be blended together to create different shades. Available in 12 colours. To assure perfect fill, greater adhesion we suggest preheating the substrate and crayons with a hot gun or a hair dryer. Product Information Sheet
