Dries in Minutes for Efficient Use
Make sure your surface is clean and dry before applying a thin, uniform coat of 3Mâ„¢ Tape Primer 94. The primed surface must remain free from contaminants prior to applying the tape.  It’s important to use the minimum amount of product necessary as over applying can cause sub-optimal results. Allow the primer to dry completely, which is usually accomplished in 5 minutes at room temperature, before applying tape. Special note: porous surfaces may require 2 applications for uniform coverage and good adhesion. Allow your first application of primer to dry before applying a second coat.
Recommended Applications
- Promote adhesion of 3Mâ„¢ VHBâ„¢ Tape
- For use on many plastic, rubber, painted and bare metal substrates
Application Tips
3Mâ„¢ Tape Primer 94Â may be applied with a brush, swab, pressurized flow gun, knurled roller or similar type of equipment and can be removed with isopropyl alcohol. Vigorous scrubbing may be required.
