Epofloor, when correctly applied and treated, is suitable for exterior use. Similarly, Pastellone can be applied to exteriors only following our recommendations. In fact, since outside there are conditions of rising damp from the subsoil, they can seriously damage the surface protective treatment and stain the finish. We, therefore, recommend it only for terraces or surfaces that have been waterproofed against rising damp. Magnesite, on the other hand, is absolutely to be avoided outdoors and where there may be stagnation of water.
