tile on tiles

[mike s]

Hi, I know it's really a no no! ,but the customer wants me to tile on some existing tiles .
i explained that they may lift in time etc...

firstly its a kitchen/diner area and a hall.20sqm in total.

shes taken up some tiles already from the kitchen area (as i advised) and there's another lot of ceramic tiles under it.
but they only cover 80% of the area (theres been breakfast bars etc there before) the rest is concrete.

The hall is all quarry tiles (from the house being built)

i thought of ether working from the quarry tiles and self levelling the kitchen area (as they also sit lower)
or getting her to take every tile up in the place.

Could i score all the tiles with a angle grinder to get a adhesive bond?




thank's in advance ...

hi
tile on tile is fine.............but probably not tile on tile, on tile

if you need to level or if tiles are removed
1 clean thoroughly
2 prime with Mapei Eco Prim T
3 level with Mapei Latexplan

Stick tile on tile or tile to levelling screed with Mapei Keraquick and grout with Mapei Ultracolor Plus (26 colours)

job done

Wouldn`t like to be tiling onto 2 lots of tiles myself, you are completely dependant on both sets then being fixed correctly and increasing the likelihood that yours will fail, surely not something you would want. Personal preference would be take them all up that way you can be sure of the substrate condition.

Tell em to take them up it will give them more ceiling hight

[ad tiling]

beware as some old houses with quarry tiles are laid with sand and cement
and under that is just the ground (ie no floor boards )
