DPF 6700 is a 2-mil (50 micron) cast highly conformable film with aggressive permanent adhesive. The film is specially formulated to conform to “hard-to-stick”, highly textured masonry surfaces such as brick, stucco, and concrete. When printed, DPF 6700 has a warranty of 1 year on masonry surfaces*.

Concrete, Masonry and Tile
The surface should be entirely dust free: high pressure TSP/water wash is the easiest method. The surface must be sealed with a complete coat of paint or concrete sealer and allowed to dry. If the surface is not sealed there must be no loose paint, grit or chalk present. All surfaces must be completely dry allowing 48 hours from surface cleaning or sealing, or 1 week from painting.
Sealing porous surfaces creates three benefits:
• Moisture cannot wick to the adhesive surface from within the matrix of the wall.
• Dust, due to ablation, cannot develop under the vinyl.
• Removal steps are much easier as the adhesive will remove more cleanly, and if any adhesive remains, the surface will be cleaned of residue more easily.
The surface temperature must be above 50°F. To assure highest adhesion the graphics will benefit from a final installation pass using a soft roller and heat source in combination. The film should be heated to a point of softening. Wait until the vinyl becomes “tack-free” and then roll the film tightly into the texture of the wall.
Addition of heat during removal will make the process much cleaner and faster. Where possible allow the surface to reach 80°F/27°C or more before removing the film. Where ambient temperature is not that high use either a very “soft” flame type torch or heat gun to bring the temperature up. Arlon recommends getting the film and under laying adhesive above 100°F/38°C.
Remove the film in a continuous smooth motion at a shallow angle for the fastest separation. Where it is practical, two people on the removal make the job go far faster than using just one. With one person working the heating unit in front of the second person who is peeling film, the job proceeds at a uniform and consistent pace. Where only one person is working there will be constant starting and stopping in addition to the problems of the heat being very inconsistent.
Because of the porous nature of all masonry and its general roughness Arlon does expect water, snow or ice to seep between the film and wall and collect on the upper edges of the applied graphic. For this reason applications to very rough surfaces do not carry the standard warranties. Those regions where extreme temperatures are experienced (freeze/thaw cycles); The warranty is reduced by 50%.
Standard warranty applies to vertical applications only. Vertical is defined as +/- 10° from the vertical. Non-vertical applications are not warranted for this product.
