The Nags Head Hammocks guys are true outdoor furniture experts. They live and breathe the stuff every day, and it was a pleasure working with them as we refinished one of their popular bar stools.
Work in a well-ventilated area. We stayed in the sun for the sake of demonstration (prettier pictures), but we recommend a shadier setting for staining, if possible. Apply evenly, following the wood drain of each section and avoiding overlap at all costs. The more even each application is, the better looking the final product will be.
We applied three coats to our bar stool, and that’s generally what we recommend. 2-3 coats every year will keep most furniture looking immaculate; stretch it out to 2-2.5 years and you’ll probably still be OK. Environmental variables, the stain used, and the wood beneath all are factors with these estimates, so keep in mind that your mileage will vary.
