New technology materials for demanding exterior painting and not only, bond with the surface, breathe, insulate, waterproof, ready colored in new modern fade-resistant shades, do not scratch, do not fade, do not peel off, do not require removal for repainting, the reinforcement underneath does not rot, does not disintegrate the surface as all elastomeric (paints) do, e.g., Hyperdesmo, etc. Wherever I applied it, I felt at ease. If you have already painted with elastomeric, remove it as much as you can to stop the corrosion and let the surface breathe. Apply a solvent-based acrylic primer, fill in the depressions with a good waterproof resin-based tile adhesive, prime with Durovit, and finally apply Cimentol. Avoid completely white color because in winter the surface will be frozen and permanently soaked, while with a nice shade, e.g., lead gray, the surface will be warm and dry, it will not disintegrate, and unnecessary energy will not be consumed for heating. Good luck.
