How Can I Fix Pumice Stones?

Pumice stone is a natural rock readily available in our country. Typically burgundy in color, pumice stone is frequently preferred in dry landscaping applications. However, due to its light weight and porous structure, pumice stone lacks freeze-thaw and impact resistance. This porous structure hinders its use, requiring direct resin application.

A recently developed, utility model-certified special mortar coats the surfaces of pumice stones. This coating is generally burgundy in color, but can also be pumice-colored if desired. When used at a certain rate (approximately 20% of the pumice weight), the entire pumice aggregate surface is covered with the mortar. This new technology increases the resistance of pumice stones to freeze-thaw wear and significantly improves their impact strength.

A water-based gravel bonding resin is used to secure pumice aggregates coated with Pumice-Stop. It's important to remember that pumice stones are inherently weak. Therefore, the purpose of securing these stones together is to prevent them from being dispersed by water or wind, and to prevent the stones from being carried away by air blowers during leaf and dry debris removal. Foot loads will be limited by the stone's inherent strength.
