Product was very easy to apply. There is a on line chat site available and they answer any questions. My house is stucco built in 1993 and it looks beautiful so I'm hoping this product will protect and preserve the beauty of my home. It did just as they said and it did nothing to change appearance at all which is what I wanted. I was very lucky to have had great weather to clean my house then on the third day after to have clear very low humidity and a great day to spray my house. So if this stuff does what it says I should have a ideal situation to provide the product a chance to work and protect my investment.
I definitely like the product.
