Abstract

A method of treating substrates, such as wood, including the steps of applying an alkali silicate solution to one or more substrates and applying an alkali borate solution with boric oxide (B2O3) content to the substrates. Substrates that have been treated using the present method include a borate-silicate polymer within the substrate. When the present substrates are wood, wood products, or green lumber, they may be used to build structures.
