Architectural Toppings & Terrazzo Overlays

InStyle Stone specialises in cement-based architectural toppings, terrazzo overlays and decorative concrete surfaces for commercial, hospitality and residential projects.

Our overlay systems are designed for projects where a refined concrete or terrazzo finish is required without the depth of a full structural slab. These toppings can be installed over suitable prepared substrates and finished through grinding, honing, polishing and sealing to create a durable, seamless architectural surface.

We work with architects, designers, builders and homeowners to develop customised finishes using selected aggregates, pigments and cement-based materials. Each system is considered in relation to the substrate, project use, required finish, slip resistance, maintenance expectations and design intent.

Technical Considerations

Every architectural topping requires the correct substrate preparation and system selection. Before installation, we assess the existing surface, movement joints, moisture conditions, floor levels, intended use and finish requirements.

Substrate preparation may include mechanical grinding, priming, crack treatment, reinforcing mesh, moisture mitigation or other preparation methods, depending on the project conditions.

Protection & Maintenance

Finished surfaces are mechanically refined and sealed using premium penetrating sealers selected for the application. Correct sealing and maintenance help protect the surface against staining, moisture ingress and everyday wear.
