Making vinyl letters stick is easy, although it is advisable to take your time about it.
The letters are supplied on a film for application, not separate from each other. They are applied just like a sticker.
See the detailed adhesion instructions.
For best results and problem free and durable adhesion, then good preparation is a must.
The base must be really clean and free of grease, and should contain no silicon. You could use methylated spirits or a window cleaner for example.
There are two methods for applying vinyl letters: the so-called 'dry' and 'wet' method. For most applications, the 'dry' method will boost the speed of operations and easily yield the best results.
The advantage of the 'dry' method is finishing more rapidly, like removing the application tape, and better control of the adhesion.
In the 'wet' method, the base is first lightly sprayed with a plant spray (a single drop of Dreft may be added to the water). This has an advantage over repositioning in the case of larger surfaces. Wait 30 to 60 minutes before removing the application tape so that the layer of glue gets a change to form a good adhesion.
In both methods the layer of glue is completely hardened and optimum adhesion is obtained after a week.
Some paint systems for car lacquer contain silicon or have a Teflon-like coating so that dirt adheres to the base less easily. Then it is very likely that vinyl will not adhere either.
Applying vinyl letters to flexible bases such as tarpaulins or boat sails is not advisable. These can contain softening agents that affect the layer of glue. Specific films are available for these applications.
The vinyl letters can be easily removed again by heating them, with a hairdryer for example.
