Frequently Asked Questions Can PermaFlex 300 Sanded Thin Set be used underwater? Yes, once fully cured, PermaFlex 300 is specifically designed for submerged applications, making it ideal for use in pools, spas, fountains, and other water features. However, tiles must be set and the mortar must be cured before filling the pool with water. What type of tiles work best with this thin set? This mortar is suitable for use with porcelain, ceramic, and glass tiles. Its polymer-modified formula provides strong adhesion even with dense, low-absorption materials, ensuring your finish remains secure over time. How long should I wait before exposing the installation to water? It is recommended to allow 24–48 hours of curing time before grouting, and a minimum of 7 days before the installation is exposed to water immersion. This ensures the thin set has fully bonded and reached maximum strength.
