Swimming Pool Tile Cleaning
We made a decision early on that we would not use any chemicals to clean or seal the tiles to ensure the water in the pool remained un-contaminated, we also setup a temporary barrier to stop any debris going in the pool and used a high pressure machine fitted with a flat surface head to prevent water flying everywhere.The process worked well and you can see the difference in the photographs above however the job did take taking longer than usual to complete but the main thing was the customer was happy with the result.
