Work has started on the job to tile the inside surface of the pool tank.  This is to save us the  job of preparing and painting the pool every few years.  This is tiresome and expensive work, and after a couple years the pool begins to look shabby.  In spite of our strenuous efforts to clean the surfaces the debris gets ingrained into the deteriorating paint and is very difficult to remove...

The first job was to grit blast the surface (and as our neighbours will know) this was a dusty and noisy job.  This was to get a clean, sound surface for the tile system to adhere to.

The next step was to coat the inner surface with reinforced waterproofing cement (tanking).  The blue netting is the reinforcing, and the waterproof cement is a really dull brown/grey

Then the tiles can go on in sheets of about 300 mm square.  It's a long and eye-bemusing task.

 Later the tiles will be grouted  to make them completely waterproof and in our case it markedly changed the appearance of the tiles.
