Application Notes
Apply Maxisil Natural Stone Silicone to clean, dry, stable, and properly prepared surfaces. The recommended application temperature is above 40°F.
Allow approximately 24 hours for a full cure before exposing the finished joint to water, moisture, cleaning, or regular use. Temperature, humidity, bead size, joint depth, and site conditions may affect curing.
Natural stone can vary in porosity, composition, texture, treatment, and finish. Confirm compatibility before full installation when working with an unfamiliar or highly sensitive stone. A test application in an inconspicuous area is recommended when appearance or compatibility is uncertain.
Use appropriate backing material where required by the joint design. For cleaner joints and easier finishing, use compatible Maxisil cleaners, SmoothTech finishing products, precision nozzles, and silicone finishing tools.
