Product Overview
Postsaver Rot Protector Sleeve designed for 75mm-100mm square fence posts.
Heat-shrink post protection sleeve engineered to prevent ground-line rot and decay in timber fence posts. Manufactured from a dual-layer barrier system combining a thermoplastic outer layer and bitumen-based inner liner, the sleeve creates a watertight and airtight seal at the critical ground-contact zone where moisture and oxygen combine to cause decay.
When heat applied, the sleeve shrinks tightly around the post surface and bonds permanently, providing long-term protection against rot, fungi, and bacterial degradation. Compatible with both treated and untreated timber posts, it significantly extends the service life of fencing, gate, and decking structures.
The 75mm-100mm size fits standard square posts, providing complete ground-line coverage and protection in all soil conditions.
Features & Benefits
- Dual-layer protection: Combines a heat-shrink thermoplastic sleeve with a bitumen sealant lining to form a permanent barrier.
- Prevents rot: Seals out moisture and air at ground level, eliminating the primary cause of post decay.
- Long-term performance: Proven to extend timber post life by more than 20 years in typical outdoor conditions.
- Universal fit: Suitable for use on sawn or planed 75mm-100mm square fence posts.
- Easy application: Applied with a standard heat gun or blowtorch; bonds directly to the timber surface.
- Maintenance-free: Provides lasting protection without the need for re-treatment or chemical reapplication.
Applications
- Fencing installations: Protects timber posts used in garden, agricultural, or perimeter fencing.
- Gate posts: Prevents decay at ground level in larger timber supports.
- Decking and pergolas: Used on structural posts in outdoor landscaping applications.
- Timber structures: Suitable for any buried or ground-contact timber exposed to moisture.
Installation Guidance
- Preparation: Ensure post surface is clean, dry, and free from dirt or treatment residue.
- Positioning: Slide sleeve over the post so it sits at the intended ground line position.
- Heating: Apply even heat with a blowtorch or heat gun until the sleeve fully shrinks and the adhesive bitumen flows.
- Bonding: Allow the sleeve to cool and bond firmly to the post before installation in the ground.
- Final check: Confirm the sleeve forms a continuous seal with no visible gaps or air pockets.
Compliance & Performance
- Material specification: Dual-layer system comprising heat-shrink thermoplastic outer and bitumen-based inner adhesive layer.
- Performance life: Independently proven to protect against decay for up to 20 years or more.
- Compatibility: Suitable for both pressure-treated and untreated timber posts.
- Temperature resistance: Designed to perform across all typical UK soil and weather conditions.
- Environmental compliance: Reduces timber waste and chemical re-treatment, supporting sustainable fencing practice.
- Important note: Apply using appropriate heating equipment in accordance with Postsaver installation instructions for full protection.
