Prepare surfaces by removing all loose scale, rust or other foreign matter in accordance to SSPC SP2 "Hand Tool Cleaning" or SP3 "Power Tool Cleaning". High pressure water wash of 3,000 - 7,000 psi is also suitable. Apply a thin film of Denso Hi-Tack Primer to serve as a primer. For structural members choose tape width that allow 1" overlap in a downward direction. Do not overlap on the underside of horizontal surfaces. Do not attempt to work with lengths greater than 6 feet. Where possible overlap from bottom upward to create a "shingle" type overlap.
Press and smooth with special attention to overlap areas. Make sure tape is firmly pressed in all angles and corners and then along flat surfaces to prevent air pockets, bridging, or stretching. Goal is to ensure intimate contact between tape and surface.
Rivets, nuts, bolts may be rounded with Densyl Mastic, Denso Profiling Mastic or the use of a second layer of Denso Hi-Tack Tape for these areas only.
