Keep an eye out on it - particularly when its cool and wet, if the concrete appears darker grey in color and damp to the touch, its actually wicking moisture from underground and delivering it into the coop! In which case, painting with a concrete sealer will definitely help. But if it was built properly, there's no need to go to the expense and ruin a brush while doing so (actually, the pump up sprayers are best, but few people keep one around for painting/cleaning and a second for fertilizer or poisons - leaving the cheap brush as the less expensive option.
