Installation Guidelines
SealBoss® 2850 SilFlex volume mixing ratio is 1 Part-A to 1 Part-B.
Before application, pre-mix Part-A and Part-B. All equipment, pumps and hoses must be dry. Avoid moisture contact with the mixture to prevent premature reaction. Plural component equipment with static mixing provision is highly recommended for optimal results.
Component A must be stirred separately and thoroughly with a low-speed paddle mixer before use immediately before application. The prepared 1:1 ratio material is to be injected with the SealBoss ® IP2C Gel Injection Pump with a silicate mixing tube of 8mm diameter, and 500mm length.
A static mixer blends both components and injects them into the mountain side, rock or soil. The curing reaction time of the urea-silicate foam formulation is significantly depending on temperature.
