Exposed Aggregate
Exposed-aggregate
(stone) concrete can almost be compared to a piece of granite or marble transformed by polishing: A plain, unremarkable surface has been stripped away to reveal the exceptional beauty lying beneath. In the case of concrete, that beauty is in the form of decorative aggregate, either natural or manufactured.The decorative process of exposing aggregate has been around since the early 1900s, well before pattern stamping, stenciling, and decorative overlays became trendy. But this method is far from being ready for retirement. An exposed-aggregate finish offers numerous advantages.
An exposed-aggregate surface is obtained by pouring concrete and then removing the outer layer of cement cream to uncover decorative coarse stone (either batched into the concrete mix or put onto the surface). Because of its durability and skid resistance, an exposed-aggregate finish is ideal for most flatwork including:
- Sidewalks
- Driveways
- Patios
- Pool decks
With an exposed-aggregate finish, you can achieve spectacular effects at a reasonable cost because few additional materials (other than the decorative aggregate) and tools are required. Here are some other notable advantages of exposed-aggregate finishes:
- The surface is rugged, nonskid, and resistant to heavy traffic and weather extremes.
- Many types and sizes of decorative aggregate are available to achieve unlimited color and texture variations.
- Exposed aggregate is highly versatile and contrasts beautifully with plain concrete or other decorative treatments such as stamping, stenciling, staining, and integral coloring.
- Little maintenance is required, other than sealing and occasional cleaning.
Applying a transparent concrete sealer to an exposed-aggregate surface can improve both its performance and appearance. These sealers—typically film-forming acrylic resins—can help protect against spalling, freeze-thaw damage, stains, deicing salts, and abrasion. A sealer will also enhance the color of the aggregate, accentuating its depth and richness.
When selecting an exposed-aggregate sealer, look for a product that:
- Is non-yellowing and UV resistant
- Will provide a high-gloss “wet look” that deepens and enriches the color of the aggregate
- Repels oil, grease, water, and stains
- Is re-coatable
