An application fluid for vinyl is a lubricant designed to prevent the adhesive on the backside of the vinyl from sticking until it’s been perfectly positioned.
Application fluid is a product that you spray as a fine mist onto the surface of the substrate you’re working on. You can also spray the same fine mist onto the back of the pre-masked vinyl and tape once the release liner has been removed. After that’s done, it’s a matter of placing the vinyl into the surface and lining it up precisely. When that’s done to your satisfaction, use a squeegee to push the application fluid out from under the vinyl, and then soak it up with some paper towel. Last step is to remove the tape and finish the job. Factors such as the amount of application fluid, the type of vinyl and the kind of tape used will all determine how quickly the job goes.
