Judging by the couple of photos and limited information you have posted.  My advice without knowing more info.  in other words sizes involved and more extensive photos is walk away.  It appears to be a job for someone with professional equipment and a lot of experience.   I am talking about high speed machines fitted with specialist brushes and a range of chemicals who is used to dealing with swimming pools!   Ultimately they only have themselves to blame for letting it get in that state.

Hi William, i have seen many swimming pool decks badly damaged by companies who used very aggressive based acids to break down these types of build up (which are usually a mix of limescale,sodium,calcium,etc. i mean tiles that were so etched from the acid clean that you could no longer even mop the decks, as Kevin has said you need a company who specialize in this area, i know one contract cleaning company in Cork William who tried to tackle one of these jobs in a large leisure centre and it ended up costing their insurance company over 200,000 grand to replace the tiles which were totally damaged from the acid used on the job.

Was that removable Jamie

[Jamie Pearson]

Yes. As you can see from the sample tile.

You need to be very careful with this type of restoration!  It can turn into a nightmare and if you use the proverbial "Builders / Brick / Hydrofluoric Acids" on it you can cause a lot of problems just from the fumes alone let alone the damage it can do to chrome and even tile itself.  Talk to someone experienced before you even attempt to tackle it!!!

Thanks tadgh,
I was keen to impress as other companies were there before me. I did a test and that was enough for me. 12% hydrochloric acid and scraping is not for me so I walked as per recommendation. When leaving I noticed some rusting along the metal grab rails so was happy to keep going

We used 3 different Bonasystems Products to get the results. It is not something that comes quickly but results are good. You need to be careful on some black tiles as some of the products can damage the colour. On this occassion it was fine and the and their anti-slip treatment works by bonding to the tiles so there is no etching worry. The first step was to remove the surface contamination with one product and black floor pads. This is the one that cant enter the pool so we needed to block off the drains in some areas and install hoses onto others connected to the wet vac to catch the run off. We then switched to a non-buffered product that is pool safe to further remove and do detail to channel drains and pool uprights then a third to increase slip resistance.

Happy to talk this through if you want to call me.

The sample is the clean tile in the picture.


Here is an area in the sauna that was a combination of body fat and calcified salts from the pool its non-chlorinated, ozonated water.


We later found out the Spa staff were dipping the mop into the pool then mopping the sides hence the extreme build up.

Thanks Jamie,
Very helpful as always. I appreciate the offer to call you but I think I will keep going. The area is just too big and it's everywhere.
