Tips and Tricks – IMAGin® StreetRAP™ Installation Basics

This month we wanted to share some basic installation details for MACtac’s IMAGin StreetRap since we’ve had so many questions lately regarding the recommended use, and application techniques. Although there is a lot of info listed below, be sure to note the highlighted sections for best practices, and for any further inquiries go to www.macac.com/graphics for a complete performance guide.

DURABILITY:

1) The outdoor durability of the completed StreetRap graphic is up to 3 months for pedestrian traffic on smooth surfaces.

REMOVABILITY:

1) “Removability” means that when removing the emblem, the pressure sensitive film will leave less than 20% of the adhesive on the substrate.

2) Lift one edge, you may need a putty knife to get an edge started, and pull using short, quick tugs. Keep the angle low, (less than 45°) for best results.

3) If any residual adhesive is present, citrus or solvent based-adhesive removers will clean the residue.

RECOMMENDATIONS:
Always test your combination of IMAGin StreetRap, inks and laminating films prior to commercial use.

1) Printing Conditions:
Print in a controlled environment. Ideal pressroom conditions are ±73°F (23°C) and 50% relative humidity.

2) Laminating Conditions:
Ensure print is completely dry. Material should be allowed to dry 24 hours prior to lamination or transportation. To meet slip resistant safety standards the printed StreetRap product must be overlaminated with Permacolor® PF6300.

3) Transportation Conditions:
To allow for easy transportation, StreetRap graphics can be rolled up, with the image out, and minimum diameter of 6 inches (15cm). During transportation or storage, avoid exposure to extreme temperature and humidity changes.

4) Application Conditions:
a) The surface must be absolutely dry, clean and in reasonably good condition. b) StreetRap graphics must be applied in dry weather to a dry surface at temperatures above 50°F(10°C) on days the temperature is expected to rise to at least 70°F (21°C). Heat helps the adhesive flow to the rough surface to create a better bond. Do not attempt to apply graphics late in the day when the temperature is expected to cool down.
c) The rougher the surface the less contact the adhesive will have and the less chance your graphic has for success.
d) To clean the surface, use a brush or stiff bristle broom to remove dirt and dust, sand and gravel or other loose contaminates. Do not use water or cleaners which will cause the surface to become wet.
e)
Bridge graphics over seams if needed; do not force the graphic down into the seam.


f) Once aligned, pull back 1-2 inches of the liner to expose the adhesive to align and start the application. Remove 6 - 10 inches of liner at a time and using a firm squeegee or a firm, short bristle brush with very firm pressure, forcing the adhesive down into the surface. Continue with 6 - 10 inches at a time to eliminate air bubble, complete the application.
g) Once complete go back over all edges again to make sure they are in full contact to the surface.
h) If possible trim sharp corners to a rounded radius to help minimize edge lifting.
i) On rougher surfaces use heat and pressure to conform at least 1” of the graphic edge down into the surface.
j) If needed, use a 1” overlap to seam the graphic. Do not have multiply layers of overlap on your graphic. This creates excessively high levels which may result in trips, falls and injuries. Stagger your overlaps as necessary.

LIMITATIONS:
1) StreetRap is not intended to be used as a conformable wall wrapping film.

2) StreetRap used on sealed concrete will result in a permanent application and will not be easily removed. Always test first in an inconspicuous area.

3) StreetRap on varnished surfaces and soft walls like stucco or drywall will damage the surface upon removal. Always test first in an inconspicuous area.

4) StreetRap is not designed for use on surface with vehicle traffic. Short term applications, like for special events or parades that last a couple days are acceptable. However, at the end of the special event immediately remove the graphic before regular traffic resumes.

* SLIP RESISTANCE STANDARDS:
Various standards-making authorities have developed different methods for evaluating the slip-resistance characteristics of walkway materials. Organizations’ including the American Society of Testing and Materials (ASTM), the American National Standards Institute (ANSI), and the National Floor Safety Institute (NFSI), have established different slip-resistance test protocols. The standard, ASTM D2047, is the oldest continuously operating protocol and the most often cited by other standards.
