One For The Tilers

[needawin]

My daughter has a property abroad. The balcony tiles are old. Although in good condition the glaze has gone and so they are easily soiled.
What can I clean them with and then coat them so them remain shiny and clean.
They are very close together. Any tips on grouting?
Lifting them is not an option.

Hiya Needy. I don't think you're going to be able to do much for the appearance if the glaze has gone........ I guess a good scrub with bleach to remove moss and mould, then maybe a good patio sealer.......

............. as for the grouting......... there are small handtools available for scratching out the old grout. A laborious job though.
I just use a small (100mm) angle grinder with a thin stone disc..........

You could try a water-based floor varnish to seal them, such as Dulux diamond glaze.
