A. MAINTENANCE SPECIFICATIONS
i. Twice annually, inspect all surfaces for flush condition and overall condition, repair as needed.
Do not stain, varnish or paint. If dirty, wood may be scrubbed with warm soapy water and
soft bristle brush. Pressure washing, steel wool/wire brushes are not recommended. Heavily
ingrained stains may be sanded away with fine grade sandpaper worked in the direction of the
grain. To clean graffiti from unfinished wood surfaces, allow paint to dry, scrape away thicker
areas until wood can be seen through paint, then sand using 80 grit, then 100 grit sandpapers
until the paint is gone. Solvents or paint removers which may damage the wood or cause it to
absorb pigments from the paint shall not be used.
ii. Quarterly, inspect and tighten all loose connections
iii. After rain events inspect and remove debris from trenches
iv. For the Ipe boardwalk, it is not necessary to perform an annual sealing or oil treatment, but doing
so can extend the lifespan of the wood boardwalk. Do to the density of the very hard woods, they
can warp or rack more severely than typical hardwoods if unevenly moist, which makes regular
oil applications important to maintain moisture levels throughout the decking. Given the proximity
to the river and the potential for VOCs in oil treatments, it may be best ecologically to not do a
sealing or oil treatment.
