Make sure the surfaces to be joined are spotlessly clean, and both the surfaces and glue at a good ambient temperature ( ie not very cold or very hot)

The first requirement is that glues must be able to creep or flow into the

crevices of the two objects that are being attached together. At the microscopic

level, even surfaces that appear smooth will, in general, be very rough - full of

mountains and valleys and crevices. The glue has to be able to seep into these

crevices. The second requirement is that the glue must be able to change its

molecular structure so that it changes from a fluid to a solid - it must harden.
