stucco problems

I need to know if there's a product to seal the exterior finished stucco on my home. We rec'd east winds with rain over the weekend and rain has infiltrated through the stucco (I'm assuming) to the rim joists and inbetween the plywood subfloor and hardwood flooring, causing my hardwood flooring to swell.
I'm wondering if anyone knows of any products to seal the stucco and how to apply the products.

Open to all suggestions.
Thanks in advance!

Welcome to the forums!

Is the stucco painted?

Unpainted stucco with no cracks [they can be filled] can be waterproofed with thompson's waterseal but waterseal doesn't hold up well to the elements - it would need to be reapplied frequently

The best way to waterproof it is with an elastromeric paint. It can be applied over most painted masonry. Raw stucco would need to be primed first. Any cracks/voids should be filled first, caulking works fine for minor cracks.
