Preventing and controlling rust spots in yellow rust stone during the processing of stone is crucial. The primary prevention of rust spots in yellow rust stone mainly involves effectively controlling the three elements that contribute to their formation: water, oxygen, and iron. It is advisable to avoid using highly alkaline cement for the bonding construction of yellow rust stone, as this reduces the opportunity for the alkalis in the cement to react with the iron in the stone. Based on years of experience in treatment, we have summarized the main effective methods for preventing rust spots in yellow rust stone as follows:

Before construction, Rust Stone must be treated with a stone maintenance agent to provide a six-sided protective coating for the stone, blocking contact between the iron within the stone and water.

2. Minimize the use of highly alkaline cement for bonding yellow rust stone, reducing the chance of a reaction between the alkali in the cement and the iron in the stone.
