Installation Procedures

(A) Permanent Installation Using DAPCO Barrier Adhesive
1) Adhesive will adhere to most clean, dry and well unified surfaces. Application temperature is 50º to 100º F (10 to 37º C).
2) Clean the spot on which marker will be placed. All surfaces must be free of dust, dirt, oil and moisture.
3) Apply adhesive 795A 1/8" thick in an "XXX" pattern to the base of the marker.
4) Place PCBM on the barrier and apply firm hand pressure for five (5) seconds.
5) Ultimate bond strength is achieved after 72 hours at 70º F (20º C).
6) Markers are now ready for traffic.

(B) Temporary Mounting Using Butyl Adhesive Pad
1) Spray areas where marker will be mounted with Primer #80. Allow primer to sit for one minute.
2) Remove release paper from butyl adhesive pad.
3) Press PCBM to primed spot on the barrier and apply firm hand pressure for five (5) seconds.
4) Markers are now ready for traffic.

 Adhesive #795 Instructions
Ideal application temperature is 50 to 100 degrees F (10 to 37 degrees C). Adhesive should squeeze up through the holes in base for better mechanical bonding. Insufficient pressure will not allow for proper bonding and may result in adhesive failure.  Contamination of application surfaces by moisture, dirt or grease will inhibit bonding of adhesive and can result in adhesive failure.

Marker Body
The marker body shall be made from a high-impact weatherable engineering thermoplastic .090" thick (min) that conforms to the properties listed in the table above right.
