Morning chaps.
Have been asked to price a re-tile in a small primary school. They want their swimming pool shower area re-done. I'm going to look tomorrow but wondered whether there was anything out of the ordinary to look out for where the area to be tiled is for "public" access ie lots of noisy kids! For example does it need expoxy grout? Are there particular Health and Safety issues to be considered?
Any help/advice gratefully recieved.
Have a good week.
Jim
