The range
Every product does the same fundamental job, stopping moisture crossing the junction, but each is formulated for the substrate it protects, and each adds the defence that substrate specifically needs.
For concrete
Stop water. Protect concrete. Last longer.
A moisture-blocking coating for concrete basement belts and concrete door and window frames. It bonds into the concrete and forms a continuous waterproof barrier: a separation layer between concrete and masonry that keeps dampness out of the paint, plaster and finishes beside it.
For wood & plywood
Block moisture. Fight termites. Protect wood.
A premium coating for wooden door frames, window frames and plywood. It penetrates to the cellular level of the timber and creates a highly hydrophobic barrier that stays breathable, so trapped moisture is never sealed in, with an added termite-resistance formula and protection against fungal growth.
For steel
Block moisture. Stop rust. Protect steel.
A high-performance coating for steel door frames, window frames, truss works and structural steel. It forms a tough film on the metal that keeps water off the surface, and where water cannot reach steel, rust cannot start. Suitable for interior and exterior use.
Choosing
Pick by what the surface is made of, not by where it is in the building. Most sites need more than one.
01
Basement belts, plinth bands, cast door and window frames, beams, columns, any damp-prone concrete.
→ Aqua Block
02
Door and window frames, partitions, plywood, wooden floors and stairs: anything that can absorb water or feed termites.
→ Wood Seal
03
Steel frames, truss works, mild-steel and fabricated members, and every point where metal is built into a wall.
→ Rust Shield

| Property | Aqua Block® Concrete | Wood Seal® Wood | Rust Shield® Steel |
|---|---|---|---|
| Substrate | Concrete & masonry contact areas | Wood & plywood | Steel & mild steel |
| Protects against | Moisture migration, wall dampness, moisture-related damage | Moisture absorption, termite attack, fungal growth, surface deterioration | Moisture, rust, corrosion, premature deterioration |
| How it works | Penetrates and bonds to concrete, forming a continuous waterproof barrier and a separation layer against masonry | Penetrates to the cellular level; hydrophobic but breathable, so internal moisture is not trapped | Forms a tough moisture-resistant film that reduces water contact with the metal |
| Typical surfaces | Basement belts, concrete door & window frames, beams, columns, damp-prone concrete | Door & window frames, wooden partitions, plywood, wooden floors, wooden stairs | Steel door & window frames, truss works, fabricated components, structural members |
