Can Travertine Table Tops Be Used Outside? A Comprehensive Guide
Travertine, a beautiful and durable natural stone, is often used for indoor furniture due to its elegant appearance. However, many homeowners wonder if travertine table tops can be used outside. The short answer is yes, but with some considerations. Let's delve into the details to help you make an informed decision.
Understanding Travertine
Travertine is a type of limestone deposited by mineral springs. It's characterized by its porous texture, which gives it a unique, rustic look. This porosity also makes it susceptible to water absorption and freezing/thawing damage, which is why it's crucial to consider its outdoor use carefully.
Weathering and Travertine
When exposed to outdoor elements, travertine can weather over time. Here's what you can expect:
- Discoloration: Travertine may change color due to sun exposure, becoming darker or developing a patina.
- Efflorescence: This is the appearance of a white, powdery substance on the surface, usually due to salt deposits. It's typically not harmful but can be unsightly.
- Etching: Acidic substances, like lemon juice or vinegar, can cause etching, which appears as a dull, frosty spot on the surface.
Frost Damage and Travertine
Travertine's porous nature makes it vulnerable to frost damage. When water enters the pores and freezes, it can cause the stone to crack or flake. This is more likely to occur in colder climates or areas with frequent freeze-thaw cycles.
Sealing Travertine for Outdoor Use
To mitigate these issues, it's crucial to seal travertine table tops before using them outdoors. A quality impregnating sealer will penetrate the stone's surface, reducing water absorption without altering its appearance. Here's a simple sealing process:
- Clean the travertine thoroughly.
- Apply the sealer evenly, following the manufacturer's instructions.
- Allow it to penetrate for the recommended time.
- Wipe off any excess sealer
