1923 stucco home in South Florida. We have gotten several bids and the process and products are all different as well as a huge difference in price, ($6900- $33,000)- 3200 sq ft house with detached garage)…  from spraying SW Duration, to applying a sealer/ spraying and back rolling one coat paint to rolling 2 coats elastomeric loxon xp. Any suggestions? Thank you.
