How Does DeckPRO Work?

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

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

Using DeckPRO with ground contact pressure-treated lumber activates our market-leading post-replacement warranty and ensures your posts last.

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.
