Can Prostone and Modulo products be used on wall areas adjacent to swimming pools?

The Prostone and Modulo Exterior product range will perform from a durability standpoint in the same manner as any quality lightweight concrete material. However, it should be noted that as with any concrete or natural material, continued exposure to chlorine and other chemicals may eventually affect coloration. When frequently exposed to water, we recommend protection with a non-film forming breather-type masonry sealer. The Interior only product range cannot be used close to pools, not even indoor pools.
