Abstract Non-conductive substrates are prepared for electrostatic pre-treatment with a conductivity-improving composition. In one embodiment of the invention, the composition comprises an alkali metal hydroxide (less than 5 weight %) and a solvent system for the alkali metal hydroxide comprising a lower alkanol and a hydro- carbonaceous co-solvent. Production line electrostatic coating techniques can be used, and the residual solvent system does not generally have an adverse effect upon adherence of the coating to the substrate. Another embodiment of the disclosed process com- bines preparatory biocidal treatment, water repellency treatment, and electrical conductivity treatment "in-line" with electro- static spray coating of wooden articles. The preparatory treat- ment can be a single step, e.g. immersing a continuously moving line of wooden articles in a treatment bath containing a solution especially designed for this process. The solution is very low in solids (e.g. less than 20%, preferably less than 10%), and the solvent for these solids contains some polar solvent.
