I used to find a bit thicker coat gave me the time, but it does seem odd as

The tin says either apply to both surfaces, leave to tack dry, then join

or, if at least one surface is porous, apply to the least porous
surface, press together immediately and hold for a few minutes while it
goes off, presumably there's some opportunity to reposition with the
second method?
