Schist masonry sealed with RTS Water Repel — ROKI Collection, Queenstown

Stone sealing · Queenstown & Wanaka

Protect the stone. Without changing how it looks.

Breathable, NZ-formulated sealers for Ōamaru stone, schist, brick, block and natural stone tile. Repel water, salt and moss while letting the substrate behave like stone — no film, no plastic look, no trapped moisture.

Why seal stone

The stone outlasts everything — if you protect it.

  • Breathable protection

    Penetrating sealers that block water without trapping moisture inside the stone — essential for soft, porous surfaces like Ōamaru stone, brick and block.

  • Stops salt and frost damage

    Water Repel and Paving Protect work against the freeze-thaw cycle that fractures Central Otago stone every winter.

  • Holds back algae and moss

    A sealed surface dries out faster after rain — denying moss, lichen and algae the moisture they need to establish.

  • Enhances natural colour

    Optional Colour Enhancer brings out the depth of schist and aggregate without making it look glossy or fake.
