Replaces Product Bulletin 270 ES Dated May 2011
1 Description
3M™ Stamark™ Pavement Marking Tape Series 270 ES (“Tape”) is a retroreflective patterned polymer pavement
marking that can be used as an inlay marking on new asphalt or as an overlay marking on asphalt and concrete
pavement surfaces in good condition.
The Tape offers “Extended Season” applications due to an improved pressure sensitive adhesive (PSA) package on
the bottom surface.
The Tape does not require 3M Stamark Surface Preparation Adhesive P-50 (“P-50”) or 3M Stamark Low VOC
Surface Preparation Adhesive SPA60 (“SPA60”) prior to application, if applied during the application season as
outlined in the 3M Climate Guide for 3M Stamark Pavement Marking Tapes
Series A270 ES: No liner. Used for lane lines, edge lines, channelizing lines, gore markings, stop bars, and
crosswalks.
.
Series L270 ES: With liner. Used to cut symbols and legends.
Series SMS-L270 ES: With liner. Precut symbols and legends.

2.2 Color
The daytime and nighttime colors of Tape conform to ASTM D6628, the Standard Specification for Color of
Pavement Marking Materials.
2.3 Skid Resistance
The patterned, retroreflective, pliant polymer surfaces of Tape shall provide average initial skid resistance
values of 45 BPN or more when tested according to ASTM E303, subject to the following modification:
o Skid resistance is calculated as the average of two measurements taken at an angle of 45° from one
another.
2.4 Patchability
Snow removal equipment and heavy traffic may cause wear and damage to Tape. Such damaged areas can be
repaired using patches made of Tape. Remove damaged Tape and replace it according to the instructions
presented in the “Overlay Applications” section of 3M Information Folder 5.7
.

3 Application
Install Tape according to the instructions presented in 3M Information Folder 5.7.
All applications should be installed using the instructions in the appropriate section of 3M Information Folder 270
ES. Surface preparation adhesive is not needed when applying the tape during the application season outlined in
the 3M Climate Guide for 3M Stamark Pavement Marking Tapes. The tape can be applied down to 40 °F (4 °C)
ambient temperature outside the dates outlined in the Climate Guide for Stamark pavement marking tapes with the
use of P-50 or SPA60. For long line applications, the P-50 or SPA60 surface preparation adhesive should be
applied with a 3M Adhesive Spray Applicator PS-14. For transverse markings, the surface preparation adhesive
should be applied using a solvent resistant 3/8 inch nap paint roller.
Road lanes are typically exposed to different levels of traffic shear exposure. Road lanes that are exposed to a high
frequency of high shear turning, especially by trucks and other large vehicles, require use of SPA60 or P50 for
application of Stamark pavement marking tapes. The following table summarized the product and surface
preparation adhesive application recommendations by shear condition:

4 Durability
The Tape is weather resistant and provides excellent retroreflectivity and color retention. The Tape is a highly
effective lane marking material and will show no appreciable fading, lifting, shrinkage, or chipping for the duration
of the warranty period, when applied according to the 3M requirements described in the 3M product literature.
The Tape’s durability depends on several environmental and traffic conditions, including, but not limited to, snow
removal practices, method of application, and pavement and atmospheric conditions at the time of application.
Damage will be caused by heavy trucks, excessive encroachment (crossover) on high ADT roadways, narrow lane
width, unpaved shoulders, snow removal and ice control techniques. It is recommended that the customer
thoroughly evaluate Tape under the conditions present at the installation location prior to large-scale
implementation.While experience has shown that, properly applied, these materials are highly effective traffic
control devices, 3M makes no generalized performance claims.
5Storage
Store indoors, in a cool, dry area. Use within one year of receipt.
