Ninety-six simulated truck floor, comprising a total of 328 wood specimens, were prepared and exposed outdoors for three years. Seventy-five were treated at controlled retention and maximum penetration, using proprietary type and experimental preservatives, sixteen pressure treated to refusal, and five untreated. All specimens were finished with two-coat systems con sisting of a new experimental olive drab oil-alkyd wood primer plus various specification topcoats. Three year exposure results indicated that the controlled retention maximum penetration treatment cycles, combined with the experimental primer and preservative contributed to a substantial improvement in outdoor durability. This report includes proposed specifications for the laboratory developed preservative and primer. Author
