So the video you see was taken today 16/9/2024 when we applied the second coat. On Saturday 14/9 in the morning, we applied the waterproof Aqua Epoxy Primer. Of course, I had only swept and blown the roof with a special machine. After I spoke with the company first so that we wouldn't do things our own way, they advised us not to wet the roof but just to clean it well, because there was a possibility of moisture being trapped in spots we might not see. So in the morning, we applied the primer first on the edges and difficult spots and then with a roller all over the roof. (I should point out that we had done insulation on the roof with lightweight concrete, a material like polystyrene, and roofing felt in 2016, and fortunately, it was in excellent condition without moisture; the additional insulation was done preventively but also to ensure there would be no problems.) After 2 hours when we could step on it, we applied the second coat just like the primer. It really went on effortlessly and beautifully; we diluted it slightly with 5% water. After 2 days, we applied the second coat. In about a week, we will apply a third coat as we have enough insulation left. The roof is 180 sq.m and we used 9 pieces of 4 kg primer, which came exactly, and 7 pieces of 25 kg insulation. Additionally, we also applied insulation to a piece of plywood we had as we stepped onto the roof, where we diluted it quite a bit (20%) so that it would work as a primer for the DS, and then without dilution, the DS again. I repeat that we did all of this following the instructions of Durostick itself based on our own needs. In the end, it seems like an excellent material; now the result will show over time, it looks very promising. I recommend it.
