Anti-condensation paint, formulated with special hollow microspheres that give a low thermal transmission coefficient so as to ensure a minimum temperature difference between the painted surface and the air. This prevents condensation and guarantees a reduction in humidity on the walls treated with less heat loss and greater resistance against bacterial attacks. It is therefore suitable for rooms with a high presence of steam such as bathrooms, kitchens, laundries, where the formation of surface condensation and mould is easier.
