deanotile

I can tell form that you were there. One of the things my uncle taught me was in the sawdust instead of water if you put raw linseed oil when you spread the sawdust on the floor and rubbed it in to the tile it would levee them looking mint. This was on quarry tiles glazed tiles as you say just put water in the sawdust. Grouting was don using a wet slurry of sand and cement and brushing it in to the joints then get a semi dry mix and sprinkle it all over the floor when you rub it of the joints are full and the tile is totally clean.
