How do the pumps work?
We sell identical pumps for the resin and hardener which, when properly primed, will dispense one ounce per stroke. The pumps will fit securely on all of the plastic bottles we send you. You will have to trim the straw to fit the smaller bottles. To prime each pump push down approximately three times which should expel the air. During this process it is advisable to have something to catch the liquid that comes out with air still in it. This can easily be returned to the bottle by unscrewing the pump. This should not result in losing the prime.
