How Does Postsaver Work?

Wooden posts rot and fail at ground level, where moisture, air and fungi thrive and attack the timber.

Postsaver’s dual-layer protection creates a total seal at this vulnerable point, forming a permanent barrier that stops decay and locks in vital preservatives.

Using Postsaver with UC4 treated timber activates our market-leading post-replacement guarantee and ensures your posts last.

Easy Three-Step Application

Heat application activates our unique dual-layer seal for maximum protection.
1 – Wrap
2 – Heat
3 – Roll
Watch How Postsaver Works

The Dual-Layer Difference -  Real protection. Real peace of mind.

Inner Sealant

When heated, the inner layer activates a complex blend of thermoplastic sealants that bond directly to the timber. This creates a permanent air and water-tight seal. 
No gaps. No moisture. No rot. 

Outer Barrier

The tough outer barrier heat-shrinks tightly around the post, forming a durable shield. Even if the timber naturally cracks or moves over time, the outer barrier continues to protect, stopping decay before it starts.

The Postsaver Seal of Quality

Postsaver is a purpose-engineered protection system, manufactured under strict ISO9001 standards for consistent, proven performance. That precision is why Postsaver is trusted worldwide and confidently backed by a market-leading post replacement guarantee. 

Unlike tape products that vary in quality and accelerate decay by trapping moisture, Postsaver works with timber, not against it.
The message is simple. If it’s not Postsaver it’s not protected.
Application

How Easy Is It To Apply Protection?

All you need is a 2KW+ Hot Air Gun or gas blowtorch, and a foam roller if you’re applying to square posts (stapler + knife required for Wrap & Tack). Postsaver rot protected posts are suitable for installation with fence post concrete.
1. Measure Hole Depth
2. Position on the post & heat shrink on
3. Install the post in all the normal ways

Frequently Asked Questions

Why doesn’t the protector cover the bottom of the post?

Beyond 15 cm or 6 inches below ground there is not enough oxygen to support the decaying organisms and fungi. Coupled with temperatures below 10°C means that these decaying organisms are unable to survive and rot cannot occur.

Can I install rot protected posts with fence post concrete?

Yes. All posts that have our rot protectors applied to them can be installed in all the usual ways - including installation with fence post concrete.

How do you know Pro-Wrap rot protection works?

Our confidence comes from our zero failure, 20-year independent field test data conducted by the BRE, Europe's largest and leading timber test organisation. With millions of rot protectors sold to over 30 countries worldwide over the last 26 years, our product is proven in volume use, and our test data confirms this.

How do you apply rot protectors? Can I apply them myself?

Yes. All you need is a blowtorch or 2KW+ hot air gun and if applying rot protectors to a square post, a foam roller. All application equipment is available to purchase from us directly.
