Start with conditions, not a product
Gulf Coast humidity and near-daily summer storms put steady pressure on tile assemblies, so the waterproofing membrane behind the tile matters at least as much as the tile pattern itself.
Build a complete scope
- Membrane system and slope-to-drain
- Grout and setting-material choice
- Substrate condition behind old tile
- Testing before finish tile goes on
- Cleanup and surface protection
St. Petersburg context
Between a high water table, frequent summer downpours, and salt-heavy air off the bay, tile assemblies here fail faster when the membrane behind them cut corners — a bigger risk in a coastal city than it would be inland.
