Does Porcelain Tub Restorations use acid for etching the tub?
Absolutely, a mild HF Acid solution (glass etch) is used to maximize the bonding process. It allows a mechanical bond as well as a chemical bond. This gives you the very best adhesion possible. Approximately one cup of diluted etch is used and is neutralized during the prep process. Some companies promote their acid free system as superior and environmental responsible relying on chemical bonding only. This is very misleading; they are cutting their cost and giving you an inferior product. Why rely on just chemical bonding when we give you mechanical and chemical bonding just that much better. Would you consider having your car or house painted without properly roughing up the surface first for adhesion, it’s the same principle here. Many companies do not use etch, cutting corners, cost, time and the training of their techs.
