A Deep Dive into Chemical Damage in Acrylic Spas

Acrylic spas are celebrated for their durability and the aesthetic appeal they add to luxury yachts and homes alike. However, they are not immune to damage, particularly from improper chemical maintenance. A scenario involving marks that mimic the appearance of stone chips around a spa’s filter canister represents a unique challenge. These marks, concentrated within a specific area, raise questions about their origin, whether from chemical damage, UV exposure, or a combination of both.

Identifying the Cause: The Role of Strong Sanitizing Agents

Through careful analysis and comparison with known cases, it becomes clear that such damage is often the result of exposure to potent oxidizing agents, such as “Tri-Chlor” tablets. These agents, intended for swimming pool use, can cause significant fading and blistering on the acrylic surface when used improperly. The damage typically manifests as peeling, scratching, and even rusting within the affected area, compounded by the bleaching of adjacent fixtures and attack on silicone seals.(insert body images here or underneath)

Navigating Repair: Sanding Through the Damage

Fortunately, there is a pathway to restoration. The affected layer can be removed through meticulous sanding, reaching down to the undamaged acrylic beneath. This process may reveal color changes due to the pigment mixing through the sheet, but such variations are often less concerning in less visible areas like the filter housing. Achieving a seamless finish requires a progression of sanding from coarse to fine grits, followed by buffing and polishing to restore the original gloss.

Special Considerations for Pre-existing Repairs

Should the damaged area include a previous repair, additional steps may be needed. A clearcoat peeling suggests chemical damage atop a repair, necessitating a fresh application of filler and protective coating. The depth and extent of the oxidized layer dictate the repair approach, with the aim of not just aesthetic recovery but also ensuring the spa’s continued functional integrity.
