I have a question about different methods of setting (fixing) tiles to flooring.:mad2:
All manufactures of tile adhesives/glues state that concrete or sand/cement screeds should be allowed to cure for a certain amount of time before the application of tiles.
I understand this.
What I don't understand is how floors tiled with porcelain tiles, which have such a low absorption rate, can be fixed with cement dust to a wet bedding of sand/cement? I am under the theory that cements rely on both the surfaces - tile and bed - to draw the moisture from the cement to create the bond.
Isn't this method - (thick-bedding) - a contradiction to what the adhesive manufactures believe, that the bedding has to be dry. I know that Im comparing gluing a floor to thick-bedding it but it comes back to the fact that the bedding is wet. And the floors done in this method have lasted and are as strong today as they were all those years back.
I did a job years back that I screeded a bed of sand/cement and then applied mapei cement based glue to the back of the tile and then tapped them in with a mallot. Their still there and their solid. The job was for the local butcher's shop entrance and it gets a good workout 6 days out of the week.
I await your knowlagable responses.
