Brick stain is a mineral-based product that penetrates the brick's surface and chemically bonds with the masonry, creating a permanent color change that lets the brick breathe. Paint sits on the surface, forms a film, and traps moisture which leads to peeling, bubbling, and spalling.
For Dakota Ridge homes experiencing freeze-thaw cycles (18°F winters to 87°F summers), trapped moisture freezes and expands, destroying painted brick within a few years.
