The 3M™ 94 Primer must always be applied to a clean and dry surface, contaminated surfaces should be cleaned with a 50/50 Isopropyl Alcohol and water mixture. Our MBS 1943 Surface Preperation Wipes are ideal for this task. Once applied, allow to dry which usually takes 5 minutes at room temperature. Porous surfaces may require 2 applications of 3M™ 94 Primer for uniform coverage and good adhesion.
