Concrete can be finished in many ways, and the right one depends on where the floor is and how it will be used. Pavilion finish is one of the less widely known options — and one of the best for outdoor areas. It gives you an attractive exposed-stone look with a textured, slip-resistant surface that stays comfortable underfoot.
What is a pavilion finish?
Pavilion finish — also referred to as acid etching — removes a thin layer of surface cement to reveal the colour and texture of the stone in the existing slab. The result looks similar to a traditional exposed-aggregate driveway, but the surface is far more comfortable to walk on, including with bare feet.
Because the aggregate is exposed evenly rather than left sharp and proud, the finish is easier to keep clean and traps less dirt than coarse exposed aggregate.
Why it suits outdoor areas
The etched texture gives the surface grip, which is why it is a popular choice around pools, on patios, pathways, driveways and barbecue areas — places where surfaces are regularly wet.
We seal our pavilion finishes with the same premium-grade penetrating sealers we use on mechanically polished concrete. A penetrating sealer soaks into the slab rather than forming a film on top, so it does not create the slick surface that some topical sealers can produce when wet.
How a pavilion finish is installed
The process starts with proper floor preparation so the surface is sound and ready. The concrete is then ground back to a consistently exposed surface, and an acid mix is applied in controlled passes to dissolve the top layer of cement and reveal the aggregate. Once the desired exposure is reached, the surface is sealed to the finish you have chosen.
Pavilion finish is unusual in that the final look depends heavily on the existing slab — the aggregate that is already in your concrete determines the colour and stone distribution you end up with. That is why it is worth talking through your slab and your expectations before you commit. The application can be carried out on new and existing concrete, but the surface has to meet certain standards first.
Benefits of a pavilion finish
- Textured, slip-resistant surface for safer outdoor use
- Comfortable underfoot — softer than conventional exposed aggregate
- Attractive natural stone appearance drawn from your own slab
- Durable outdoor surface built for Australian conditions
- Low-maintenance — a pressure wash or a stiff broom and hose keeps it clean
- Suits pool surrounds, patios, alfresco areas, pathways and driveways
Is a pavilion finish right for your project?
If you want the look of exposed stone outdoors without the harsh texture, a pavilion finish is usually the answer. If the area is indoors, or you want a mirror-gloss finish, mechanically polished concrete or grind and seal will suit better. We are happy to walk you through the trade-offs before you decide.
