Why Tile Condition Matters Before Resurfacing
Many DFW pool owners keep their existing waterline tile when resurfacing the pool shell — meaning any calcium scale on that tile will still be visible against the brand-new surface finish unless addressed as part of the project.
Timing the Cleaning Right
Calcium removal is generally best performed either shortly before the resurfacing crew begins work, or immediately after resurfacing is complete once the pool is refilled and the new finish has cured — timing depends on your contractor's process.
Protecting a Fresh Investment
Once resurfacing is complete, applying a protective sealant to the existing tile ensures your fresh pool finish is complemented by equally clean, scale-free tile rather than showing years-old buildup.
