You can roll Contact Cement on, just do a strip down the middle, adhere that portion , then work out one side a roller width at a time.
Cover the roller and pan with plastic wrap as soon as you roll a strip and it will not thicken up nearly as fast.
More in the pan is better too.
Put a number of them on that way back in the 70's never had a problem.
Spray would be faster, but I don't know about better.
