This report outlines the initiation of a field test to evaluate the effect of maintenance on the service life of wood decks. Decks were untreated or treated with one of three preservatives and either uncoated, or coated with a semi-transparent stain or a solid colour stain. Twelve pairs of mini decks were installed at FPInnovations' 2665 East Mall location in July 2012. One replicate will receive maintenance as needed and the other will receive no maintenance. Annual ratings will determine the necessity of maintenance. By determining how maintenance contributes to durability performance of wood decks we hope to make appropriate recommendations on the use and care of exposed exterior wood products.
