SUNOX application liquid is the perfect aid for applying window film. The concentrate is sufficient for dilution in 500ml water, enough to apply a total of approx. 6m² of film. The mix of concentrate and water is required as the window film has to be applied wet - this is not an adhesive (all SUNOX films are self-adhesive). It's best to put the liquid and water in a spray bottle; the more concentrated the mix, the better the film can be slid into place during application. Thus your film can be fitted without any bubbles of creases. As an alternative, you can also mix water with washing-up liquid, but we do not recommend this, as this can make the adhesive on the film turn cloudy.
Please also make sure that you follow the fitting instructions to the letter.
