Application Notes
Apply Maxisil P 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, pool chemicals, immersion, cleaning, or regular use. Temperature, humidity, bead size, joint depth, and site conditions may affect the actual curing time.
Do not apply the silicone to wet or actively submerged surfaces unless current Maxisil technical instructions specifically permit that application method. Maxisil P is intended for underwater service after it has been properly applied and fully cured.
Confirm compatibility before beginning a large installation or using the product with unfamiliar pool finishes, tile, coping, stone, metal, glass, plastic, or other substrates. A test application in an inconspicuous area is recommended when compatibility or appearance 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.
Color Selection Notice
Maxisil P is available in a range of colors designed to coordinate with pool tile, grout, coping, stone, and surrounding aquatic finishes.
Use the Maxisil Color Matcher to help identify the closest color for your project.
Colors displayed online are provided for reference only. Actual color appearance may vary because of monitor settings, lighting, surrounding materials, water conditions, surface texture, and production differences. A physical color sample is recommended when an exact match is required.
