I had stucco and the wood underneath that was absorbing water, causing this stucco to crack. I was advised by my stucco contractor to get the stucco sealed. I had heard about Rhino Shield and decided to give them a call. Long story short, I went with them and couldn't be happier. When we signed the deal, the salesman asked why were weren't acting happier. Frankly, we were unenthused to be spending more money to get the stucco painted. However, the paint job turned out better then we imagined. Time will tell if it holds up as advertised but we have the 25 year warranty to back us up if anything goes wrong.
