Does Stucco Need to be Sealed

I'm trying to get some opinions on sealing stucco. . .

The builder of our home insists in their warranty that we seal the stucco surfaces of our home. I have read varying opinions on this so I thought I'd request some insights from the forum.

Thanks for any thoughts you have.

Since I'm a painter, my thoughts might be biased

IMO stucco will always last longer if it has a coating to protect it. That prevents moisture from entering into the stucco and possibly causing damage. In some cases it may also stop the water from penetrating through the stucco and harming whatever might be on the other side.

I prefer a latex primer followed by latex house paint [house paint is higher quality than masonry paint = lasts longer] Use elastromeric paint for a top coat of water penetration is a concern.
