Sounds like the problem is with the bonder. You should not need a primer with this system.
To apply IBD colour gels as a natural nail overlay:
Prep nail in normal way & ensure the surface is free of shine. Any shine & product will lift.
apply bonder in small circular motions "scrubbing" it into the nail - it must be dull & grainy or product will lift. (If it isn't - dab at it with IBD sponge - this works well)
cure Bonder for AT LEAST 1min
Apply layer of clear gel, then cure 30secs
DO NOT wipe!!!!!
Apply gel polish, cure 3 mins.
If needed - apply 2nd coat of polish & cure 3 mins (shouldn't be necessary but sometimes happens)
Apply clear topcoat - either ultraseal & cure for 1 min, or you can just use clear gel & cure for 30secs (this gives a thinner result)
If you are still getting problems it could be that your lamp isn't up to scratch. Is it the IBD one?
