Choosing points
- Best for walls, gates, and local exterior scenes where a light soft stone character is wanted.
- It can be cut into blocks with soft edges and saw marks.
- Pores and weak layers collect dirt and water.
- Color ranges from beige and gray to greenish tones.
How it ages
- Often less durable than dense stone; water, freeze-thaw, salts, and abrasion can erode the surface.
What to avoid
- Do not use soft porous tuff in constant wet, freeze-thaw, or high-load edge conditions without specialist confirmation.
