Repairing Detached Tiles in Your Swimming Pool — Permanently
Detached tiles are one of the most common—and costliest—problems in older tiled swimming pools. A single loose tile may seem harmless, but in practice, it is almost always a symptom of deeper issues: cracked grout, frost damage, concrete expansion, and chemical degradation of the mortar. Re-adhering locally is a temporary fix that will recur elsewhere within two to three seasons.
For pool operators, municipalities, holiday parks, and wellness centres, this creates a maintenance spiral: annual repairs, colour discrepancies, sharp edges, and escalating safety risks. The sustainable solution is not a repair—it is a renovation where the entire tilework is levelled with epoxy mortar and finished with a professional swimming pool coating. ACRATON® Dolphin, deployed globally since 1969, has been PoolFIX's first choice for this approach for decades.
Why Detached Tiles Always Reappear
A detached tile is rarely an isolated defect. The cement-bound grout surrounding it is usually already weakened by years of chlorine exposure, frost-thaw cycles, and thermal expansion between the tile and substrate. When you re-adhere one tile, the tension in the surrounding grout remains active—and that tension will find an escape route sooner or later.
Furthermore, it is extremely difficult to match a new tile in colour to tiles that have been exposed to UV radiation and chlorine for years. The result: a patch-up effect that permanently damages the pool's aesthetic.
The Real Solution: Levelling and Coating
PoolFIX advises operators facing structural tile problems to transition to a flat epoxy coating. The existing tilework is first thoroughly blasted, then all relief is filled with a 2-component epoxy mortar, and the entire surface is finished with two layers of ACRATON® Dolphin coating (dry film thickness 300 µm).
You will no longer have tiles and grout that can become detached. Instead, a single continuous, hygienic, and smooth surface is created in the colour of your choice—from the official ACRATON® colour chart with 8 codes (2040 to 2058).
What This Means for Operation
A renovated pool with ACRATON® Dolphin demonstrably requires less maintenance. No annual tile inspections, no loose grout coming into contact with chlorine, no risk of cuts to bathers. Total maintenance and liability costs often fall below those of conventional tile maintenance within three to five years.
Based on photos or a brief inspection, PoolFIX can estimate the required volume of coating and mortar and refer you to a certified applicator in your region.
Suitable for Your Pool Type?
This method works on virtually any concrete or largely concrete basin with traditional ceramic or glass mosaic tilework: public outdoor pools, school and sports pools, hotel pools, wellness centres, holiday parks, and larger private pools. Different protocols apply to liner or polyester pools—we advise separately on those.
