Maintenance To protect your investment, J&N Structures recommends painting your building within one (1) year of purchase. If you prefer to retain the natural look of the wood, a clear sealer may be used. For a longer paint life, we suggest painting in dryer seasons, when the siding holds very little moisture. Built for Longevity We take all the necessary steps to be certain you are investing in a sound structure that is protected for years to come. Our buildings endure the daily wear-and-tear inflicted by horses and harsh weather conditions ... even transportation from one site to another.
