I am getting very confused with advice about tiling. I am about to purchase some floor tiles to go into my family/dining/kitchen and hallway.
They are called skylight lappato 600 x 600. I have been told by two different retailers that they do not need to be sealed.
My tiler however asked me to do a test with a marker pen and see if it washed off completely, which it almost did, left a barely discernible mark. He said that if the pen does not completely wash off then the tiles will need sealing every few years and that is a costly exercise along with the fact I would need to leave the house for a few days.
Can anyone give me some advice on this?
