A good depth of impregnation gives the Dry-Treat sealer protection from weathering and traffic. It also can stop unsightly efflorescence salts reaching the surface of the building material. The uniform depth of penetration of the treatment can be measured relatively easily by breaking a sample piece of treated material that has had time to cure and measuring the "dry" section depth from the surface after it has been soaked in a water-based dye for a few minutes. The depth of penetration achieved will vary with the surface absorption and amount of product applied. The more product applied will result in a deeper depth of impregnation.
In addition, Dry-Treat sealers contain a relatively slow moving reacting 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.
