Camil began the process by applying a water diluted bitumen mixture. This would make it possible for the next layers of non-diluted bitumen to stick to the surface.
We would leave each layer to dry for at least 8 hours before applying the next one. Luckily, the sun was on our side and it would really speed up the drying process.
There was a crack in the rubbery covering of the roof that we had to fix up next. So, using a broom and a smaller paintbrush the thick mixture was applied. One had to work fast, because the heat made the mixture dry faster through evaporation. Following was a white sheet of synthetic material, which would provide a fibrous and somewhat spongy surface for the goo to attach well. Whenever applying hydrated substances to a surface a fibrous layer or material is necessary, because it prevents the formation of cracks in the finished product by holding it all together. What followed was a bit of work, then waiting for it to dry, and more work on the next day. In the end we got a good, matte black roof, which was really pleasing to the eyes. I then covered it with one last special UV protection layer, brick coloured, which is mandatory if one wants to have a long-lasting roof over their head.
