All hidden in it's technology. For example; Dry-Treat impregnating sealer technology is different. The special penetrating sealer molecules are hundreds of times smaller than competitor stone sealers and penetrate much deeper into the pore structure, even dense natural stones like granite. Inside the pores our special sealing molecules bond permanently by chemical reactions , creating a substantial, deep oil and water-repellent barrier. The deeper Dry-Treat barrier, not only provides great surface stain protection, but also protection against more serious common types of damage cause by water ingress (penetration), including efflorescence, salt spalling, freeze-thaw spalling, and picture framing.
