Clean & paint Asbestos Shingles
My 100 year old house has white asbestos shingles. There is a thin dirt line right where one shingle overlaps the one below it. I want to pressure wash the whole house but if I aim the gun upward into the line of dirt I fear I will push water behind the shingles. Will the product "30 Second Outdoor Cleaner" be enough so that after 3 sunny days I can add "Emulsi-bond" by Flood to my acrylic primer and apply primer with an airless sprayer followed by 2 coats of flat acrylic paint?
