Choosing points
- Best for exterior floors where you want more texture than concrete but more practicality than stone.
- Aggregate size and color define the look more than the cement color alone.
- High spots polish with foot traffic while recessed cement collects dirt.
- It gives grip outdoors without looking like ordinary broom-finished concrete.
How it ages
- Durable when bonded well, but loose aggregate, poor curing, and freeze-thaw can cause surface loss.
What to avoid
- Do not make exposed aggregate too coarse on barefoot areas, ramps, or entries; it can be painful, slippery, or hard to clean.
