Redwood lumber is very soft and lightweight yet has a decent strength to weight ratio. It is fairly abundant and reasonably priced making it a good choice for building projects. Though Redwood is moderately resistant to rot by nature, it does still require a weatherproof sealant for outdoor uses.
Using a good wood preservative like TWP will prolong the life of a redwood surface as well as enhance its natural beauty. The best TWP Stain for redwood is the 100 Series Stain. It comes in a variety of semi-transparent color choices to enhance the natural beauty of any redwood surface. TWP 100 Series has deep penetrating properties that seal out damaging moisture. With up to 40% solids it offers excellent protection from UV rays that cause discoloring and fading.
