Filled resists. Open pore absorbs. That is the whole story.
Stain resistance is not a property of the stone, it is a property of the surface. The same pigment behaves completely differently with the pores open or closed.
A filled cast travertine face resists most household staining because there are no open pores for liquid to enter. An open-pore face will take up oil, wine and soap into the pits and needs prompt cleaning. Neither face needs a film-forming sealer, which can trap moisture.
| Stain | Filled face | Open-pore face |
|---|---|---|
| Red wine | Wipes off if prompt | Can leave a mark in the pits |
| Cooking oil | Wipes off | Absorbs; needs a poultice |
| Rust runoff | Surface only | Can lodge in pores; treat with a rust remover |
| Soap and shampoo | Wipes off | Builds up; needs brushing |
| Cement slurry | Remove before cure | Hard to lift once cured |
| Pencil and marker | Solvent wipe | Sits in the texture |
What to do when something lands
Why not just seal it
A film-forming sealer on a cementitious panel reduces vapour movement and can trap moisture, which shows as a patchy sheen or a blush. A penetrating sealer slows uptake but does not close the pores and needs reapplying. On a filled face, neither is necessary.
Questions buyers ask
- Does travertine cladding stain in a bathroom?
- A filled face does not stain under normal bathroom use. An open-pore face in a shower will discolour from soap and oils; it is a question of when.
- Should cast travertine be sealed?
- No film-forming sealer. A penetrating sealer can be used on an open-pore exterior face where dirt uptake is a concern, but it needs maintenance.
- Can a stain be removed from an open pore?
- Usually with a poultice, if it is treated early. Oil that has cured in the pores over months may leave a shadow.
