Seal Cracks in Stucco
I just saw a similar post on this, so I think I have some info now....
My house has a stucco finish, 6+ years old. When I purchased it, 2 years ago, the inspection found some "minor cracks that should be sealed". Im finally getting around to it
I understand that cracks can be very bad with stucco as water can get to the wood interior.
Called a masonary contractor who said I could probably just caulk it, but then i would probably have to paint it too!
Stucco has ridges on it, so its no smooth. Is white, but Im not sure if it has been painted.
Any tips?

I always caulk minor cracks as part of the prep for painting stucco.
Since your stucco is white you may get by with using a white acrylic latex caulk and not painting over it. At any rate it would be better to have the caulk show a little than have any water infiltration.

How big a crack does it have to be to make sure it is caulked before painting? I have 70 yr old stucco, never painted, and want to paint it. it looks pretty good to me, with a couple minor cracks, and maybe some hairline ones.
Also, if there is a patch that had a wood porch roof right into the stucco, and you want to take the roof down, what do you put on the surface of the gape, to make it look like the old stucco finish?
I know I am asking, and not replying, but am new, and don't know how to start new question in this subject area.
Thanks

At the top of each forums section there is a button that says 'new post' just click on it to start your own thread 
Stucco is similiar to mortar mix so you can use it for repairs. A lot depends on what's in [or not in] the hole but you may need to insert felt [vapor barrier] and wire [for the stucco mix to adhere to] It may take several coats to build it up almost level with the existing stucco finish. Then it's just a matter of duplicating the stucco finish.
If you can describe the finish or even better supply a pic, one of the masons can give you detail on how to duplicate it. www.photobucket.com is a free site most use to load pics.
Most paints won't hide any cracks in the stucco but an elastromeric coating will. It's heavier bodied and doesn't go as far but does a good job at waterproofing most stucco. It like any good paint job, requires a primer first. You will always find better coatings [and advice] at a real paint store, not a big box paint dept.

MyQuestion: Similar to bheron question...would that acrylic chaulk work on those joints between the pre-fab quoines and keystones also? Thanks
