Tiling directly onto tiles

[robbieee]

Hi,

I have a small porch area 1.4m2 in area that already has old tiles down. They are securely in but are discourled badly. So my idea is to tile directly onto. However what adhesive and primer would you use? Ideally something from mapei as i can get that locally from screwfix.

Any suggestions and/or advice would be welcome...

Any cement based (bagged) flooring adhesive will do this for you. By some acrylic or sbr tiling primer at the same time, just a small amount will do. Mix the primer with some handfulls of dry adhesive and paint it on the tiles. Let it dry and then tile over it. The primer and adhesive mix is called a slurry coat and aids the bond.

So can I use bal sbr with a bagged mapei flexible adhesive? Bal don't do small bags and I'm only doing an area of 1.4m2
