Adhesive Sprays—How long should I wait before making the bond?

How long should I wait before making the bond?  Pretty simple test; after spraying the surface, wait a couple minutes.  Touch the sprayed surface.  If the adhesive transfers to your fingers – WAIT.  If it feels sticky, but doesn’t transfer to your fingers, MAKE THE BOND!  Be certain you’ve indexed (aligned) both pieces before making the bond.  Once the two pieces touch, they’re “forever”.  Trying to separate them will result in destruction of one or both substrates.

#185 is an industrial spray adhesive.  It has been on the market for almost 20 years and has become the accepted standard for quality and performance when bonding most medium to light weight substrates.  #185 is used for bonding fiberglass insulation to most any substrate, bonding polyethylene and other flexible foams to themselves or other substrates.
