The film is so far fine, but should be applied to a smooth surface. Woodchip expressed by definitely. Solution is a very thin pressboard from the hardware store (for about 3 euros), which as a base is then excellent! (Anmerkund: can can also thin strips still be edged, so that will not be painted moreover / be ...) also should the film always little by little (best for couples: a glued, the other holds the rest straight up) will be replaced horizontally and immediately applied to the appropriate surface. For me, the pressing of the film worked best with your hands, everything else (eg spatula, etc.) may damage the film or make unsightly wrinkles.
