RotGuard™ Post Wraps
Precision Ground-Line Protection for Wood Posts
Protect fence posts from rot and moisture damage before it starts.
RotGuard™ Post Wraps are precision-sized, self-adhesive ground-line wood post protection sleeves engineered to prevent soil-line rot — the most common failure point in fence, deck, and gate posts.
Designed for professionals who value speed and homeowners who want simplicity, these pre-sized wraps deliver long-lasting moisture protection exactly where wood is most vulnerable.

Pre-Sized for Common Post Dimensions
RotGuard™ Post Wraps are available for:
• 4x4 wood posts
• 5x5 wood posts
• 6x6 wood posts
• 8x8 wood posts
Pre-cut sizing means faster installation in the field.
No measuring.
No trimming.
No guesswork.
Contractors working with nominal or dimensional lumber can select the correct size and install it immediately.
If you know your post size, you’re ready to wrap.
Fits Square, Rectangular, and Round Posts
RotGuard™ Post Wraps are designed to fit:
-
Standard dimensional lumber
-
Nominal lumber sizes
-
Square and rectangular posts
-
Round wood posts (based on circumference)
Each wrap provides secure ground-line coverage while maintaining tight adhesion around the post surface.
Backed by a 25-Year Warranty Protection
When installed on pressure-treated lumber or heartwood cedar posts, RotGuard™ Post Wraps are backed by a 25-year limited warranty.
Protect your investment before it goes into the ground, not after it fails.
Why Ground-Line Protection Matters
Wood posts most often fail at the soil line due to:
• Constant soil moisture
• Oxygen exposure
• Warm soil temperature
• Freeze–thaw cycles
• Long-term ground contact
Even pressure-treated lumber and naturally rot-resistant cedar can deteriorate without proper ground-contact protection.
Install protection before setting the post, not after it fails.
Engineered Polymer Adhesion - Built to Stay Bonded
RotGuard™ Post Wraps are manufactured using SBS-modified bitumen, a polymer-enhanced waterproofing membrane engineered for flexibility and long-term adhesion.
SBS (Styrene-Butadiene-Styrene) transforms traditional asphalt into a rubberized, elastic membrane that cold-bonds directly to wood fibers — without requiring heat or torch application.
This cold-flow bonding performance allows the wrap to:
• Conform tightly to dimensional lumber
• Embed into the wood grain
• Maintain consistent soil-line contact
• Move with natural seasonal expansion and contraction
Unlike heat-shrink or torch-applied sleeves that can stiffen or separate over time, SBS-modified membranes remain flexible, helping the barrier stay sealed where protection matters most.
This is precision ground-line protection engineered to stay bonded, not just coated.
