WORST PAINT EVER

So i used the Duram Armatec for the first time on my house and the drum says 4 - 6 hours drying time after 3 days it rained and all paint came running down the walls.. not only my house but my brothers house as well same thing.. Made contact with the rep Keoma sent him pics over whatsapp and still waiting weeks later an outcome.. worst paint ever, false information on products.
