Plywood is a versatile and inexpensive material that can be used for a variety of projects, including trailers. When exposed to the elements, however, plywood can deteriorate quickly. Here are some tips on how to protect plywood on a trailer:
1. Apply a sealant: A waterproof sealant will create a barrier between the plywood and the elements, helping to prevent water damage. You can find sealants specifically designed for outdoor use at most home improvement stores.
2. Use marine-grade plywood: If you plan on using your trailer in saltwater or other harsh conditions, it's best to use marine-grade plywood, which is treated to resist rot and decay.
3. Cover with an tarp: When not in use, cover your trailer with an tarp to protect the plywood from sun damage and excessive moisture. Be sure to secure the tarp so it doesn't blow away in windy weather.
