X4 is a clear penetrating sealer designed to weather and moisture proof natural stone, split faced/fluted block, stucco, mortar, cinder block, stucco, EIFS, tile, pour-in-place concrete, pavers, brick, grout and masonry against the destructive forces of the environment. It is breathable while resisting wind driven moisture, dust, dirt, graffiti, salt, acid rain, efflorescence, alkalis, freeze-thaw damage and spalling. X4 reduces capillary action of these materials by a minimum of 97%. It is water-based, non-flammable and low VOC meeting both LEED IEQ Credit 4.2.

    • Moisture from wind-driven rain can gradually or abruptly raise the moisture content of exterior materials like concrete, aggregate, mortar joints, EIFS, stucco, wood, and composite materials. As moisture content increases, mold, moss, algae and other unsightly biologicals can grow and spread. In addition, from season to season, this increased moisture content, especially through freeze-thaw cycles, can lead to unrecoverable expansion, contraction and erosion of surfaces, drastically reducing their life expectancy. Finally, as increased moisture content wicks or migrates (as liquid or vapor) gradually into the structure substrates and cavities without the ability to dry, conditions that support mold growth are likely to occur.
