A good depth of impregnation gives Dry-Treat sealers ample protection from weathering and traffic. It also can stop unsightly efflorescence salts reaching the surface of the building material. You can test the uniform depth of the treatments penetration by breaking a sample piece of treated material that has had time to cure, soak it in a water-based dye for several minutes, and measuring the depth of the 'dry' section from the surface. The depth of penetration achieved will vary depending on the surface absorption and amount of product applied. More applied product will result in a greater depth of impregnation.
In addition, Dry-Treat sealers contain a relatively slow moving reactive liquid, with a viscosity similar to that of water. This means that even on slightly moist building materials over time it can displace the water and penetrate deep into the material. This is quite useful for the treatment of those parts of a marine structure that are in the tidal zone.
