I have a pool with pebble finish that the mortar has faded in some places ( mostly on the bottom around some fiber optic lighting). All the areas where it has faded are areas that there are a lot less pebbles than the other areas which look perfect. I think this is call under exposed. Any ideas on why this happened and can the origonal dark color of the mortar be restored ?

  • United Chemical has one that I have heard good reviews about although I haven't used it myself. It's called No Dran Acid Wash (No, that's not a typo -- there is no "i" in drain in the product name).

  • Randy check out United Chemical
  • Thank you for your reply, do you know the name of the acid wash product that can be used without draing the pool?

    There may be some actual "fading," this does happen to some extent, but it may be that there is scaling too. Calcium scale is a white crust layer that can build on the surface and make colors look faded. Look closely at the "faded" areas. Check your chemical balance and adjust if necessary. The beauty of PebbleTec is that it can be acid washed without damaging the finish. There is a no-drain acid wash on the market too.
