Armenian Gold Felsite is generally suitable for exterior applications, including in rainy climates. Felsite is a type of volcanic rock that is known for its durability and resistance to weathering. It is commonly used in outdoor applications such as paving, cladding, and landscaping.

However, when using Armenian Gold Felsite in a very rainy climate, proper installation and maintenance are crucial. It is important to ensure that the stone is sealed properly to prevent water absorption, as excessive moisture can lead to staining or damage over time. Additionally, regular cleaning and maintenance will help preserve the stones appearance and longevity.

Consulting with a professional stone supplier or installer is recommended to ensure the suitability and proper care of Armenian Gold Felsite for your specific climate and intended exterior applications.
