Almost 30yrs ago I was introduced to a somewhat unknown, and perhaps region al, paint brand, BLP Mobile. I mentioned it to a painter who was a parishi oner of mine and it was evident he did not like it. But his comment told m e why, the major brands went on smoother and easier. However, the guy acro ss the street from our house has been using it and had painted three walls of his house a year apart. You could not tell the four yr old paint from t he one year old. THAT is saying something here is the soggy and moldy Sou th.
We (I) forgot to specify when we built our house, back in 92 and the builde r used Sherwin-Williams. It looked great, but started having serious milde w problems a couple of years later. We washed it down several times and fi nally had to have it repainted. I insisted the painter put on two coats of Kilns and then two coats of BLP Mobile. That was about eight or nine year s ago. While we still need to wash (not pressure wash) the porch a couple of times a year, we do not have a mildew problem.
So, if you live in a high humidity area, you might give it a try.
