Need more info like how wide are the cracks were do they start at , how many are there ?
Are these cracks structural ?
Are the cracks at the corners of windows & doors ?
Do they look like a road map ?
How old is the stucco ?
Is it conventional stucco ?

As far as I know conventional stucco. Most cracks are thin lines mostly vertical in nature don't really remember any extending from windows or doors but they might. I will be doing a closer inspection tomorrow. Just looking to seal the obvious cracks before the cold weather sets in

Are they shrinkage cracks or because of movement / settlement ? are there more on the sunny side than the shady side?

I am not a painter but I do a very large volumn of stucco and stucco repairs.
The vertical cracks would indicate warped studs or studs that carry a larger load than than others.
I have seen cracked stucco covered with Sherwin-William's Loxon it did a very nice job of covering the cracks.
The painter did cover all cracks first before coating the substrate.
I would NOT recommend the use of any ELASTOMERIC coating over stucco i have seen many failures with these coatings.

keninaz,

Pick some exterior acrylic caulking at your local HD (check the label), and apply into the cracks, also use your finger to push the caulking in and a little bit on the stucco surface, then use a sponge to level it off to match the stucco.

In my city 95% of the homes have stucco exterior and this is how we fix cracks and avoid further damage when the rain comes. Some good repairs can last for years.

For smooth stucco finish in my area, we do use Elastomeric paint to fill and hide hairline cracks.

I used and sold a lot of 'stucco patch' in S Florida where everything is stucco. The product I used, and was sold many places was Vin Lox. It came in either a 'brush' grade, or a 'knife' grade. The non magical difference in the two was that the 'brush' grade was the same as the 'knife' grade with more water mixed in.

So, you could make your own brush grade out of knife grade if you could thin it with water.

Point being that if you have 'hairline' cracks less than a 1/16" you just brush it on. Bigger cracks would take the thicker product. There are multiple stucco patches on the market. And I would not hesitate to use an 'elastimeric' paint on hair line cracks. As long as the surface is clean you are ok.

If you have fine 'spider web' cracks over large areas, make life ez and just roll on a heavy bodied elastomeric. It just needs to be clean of any dirt or chalky old paint.
