The paint on my house only lasts a short time (year or two) before it peels and turns black, especially the roof.
Its cement, two story with a pitched roof. I think its mildew that is ruining the paint and turning it black. The peeling I am guessing is from poor prep. Any painting experts here have an idea? Dominican wife says its from poor prep the first time painting and not mildew. Its time to do it again and I am tired of it.
My idea is that I need to thoroughly pressure clean and scrape the old paint off as much as possible, then smooth the surface and lastly wash with trisodium phosphate and then add anti mildew powder to the new paint. Am I missing something here? I am a mile or so from the beach and up on a hill.
Wife wants to cover the concrete roof with tile which will cost like $3000 USD. but would cover up the roof surface and look nice.
One last question. In the past I have bought the paint from the big paint supply store in P.P. down by the power plant. I am able to buy paint in the US and ship it down in a carton if necessary and the quality of the paint is part of the problem.
