Cementitious, not resin-based
Spray crete is a polymer-modified cementitious slurry — Portland cement, fine aggregates, polymer additives for flexibility and bond. Because it's cementitious, it handles UV better than most epoxies, doesn't amber over time, and has a thermal expansion rate close to the slab below it. That last bit matters: it expands and contracts with the slab rather than fighting it.
Sprayed, then shaped
The slurry is sprayed onto a pressure-cleaned and primed substrate using a hopper gun. While it's still wet, it's worked with trowels, stencils, brooms or rollers to create the final texture. Sandstone, bluestone, slate, pebble, broom-finish, stencilled paver — the look is shaped during the application window, before the cement starts setting.
Sealed for Sydney sun
The decorative coat itself isn't the wear layer — the sealer is. Every spray crete job gets a UV-resistant sealer top-coat that locks in the colour, maintains the slip rating, and protects against pool chemistry, salt spray, and Sydney humidity. The sealer is the part that needs occasional refresh; the spray crete underneath stays intact for 15+ years.
