Travertine Settings

When laser cleaning Travertine, watch out for its high porosity right from the start—I've seen it soak up heat unevenly, which can lead to micro-cracks if you're not careful. This natural stone, like a spongy limestone, differs from denser rocks because it traps contaminants deep inside, so you need to go gentle to avoid pulling the surface apart. Tends to heat up slowly due to poor conductivity, meaning prolonged exposure risks surface spalling. Start with lower power settings and slower scan speeds to let the laser gently loosen dirt without stressing the pores. This works best when you overlap passes lightly, pulling grime out layer by layer. I've found multiple light treatments clear buildup effectively while preserving the stone's texture for heritage sites. Just avoid high energy bursts—they'll scorch the calcite base and ruin that classic banded look. Adjust based on soiling thickness, and always test a small area first to keep things safe.
