This property is located along a busy state highway with high visibility. The owner, Nappen & Associates, wanted to update the exterior appearance of this building to better reflect the interior’s attractive layout and appearance. A number of samples were applied to the exterior of the building including: Super Color Stain VO (a penetrating, water based, acrylic stain for vertical concrete and masonry) and M3P Stain (a completely inorganic potassium silicate stain that provides long-term protection and enhanced aesthetics of structures. The owner selected M3P Stain, diluted 2 parts M3P Stain to 1 part Primex. M3P Stain reacts chemically with the substrate to form an insoluble crystalline structure transmission. The slightly diluted M3P Stain allowed the underlying texture and natural color variation of the bricks to remain. By changing their overall color from orange to a contemporary tan they became a permanent component of the substrate and allowed 97% vapor transmission.
