Ceramic floor tile adhesive..

[merlecollins]

I will add my two penneth for you
If this was my job and I had arrived with this 'epoxy paint' already down I would be:
1. Mechanically removing the paint and bitumen residues using a grinding machine suitable to the floor area size with a dust extraction kit.
2. Assuming it is free from deflection, overboarding the chipboard with Hardie Backerboard as per manufacturers instructions.
3. Screeding the conctrete with a suitable SLC up to a flush height with the HBB, leaving a movement joint between the two.
4. I would be taking a look if it was possible to set a full tile away from this movement joint. In that I mean does it leave you with any silly small cuts anywhere.
5. Installing a preformed movement joint at the junction between the two floor constructions with an infill colour to match whatever grout you intend to use or alternatively you could just leave this joint ungrouted and fill with a suitable flexible sealant.

Hope that makes sense to you

And get a decent adhesive, such as Mapei Keraquick for the whole lot.

I got the following email from Construction Chemicals ...

You will have to prime the surface with a cement/SBR slurry prior to tiling. Dilute SBR 1 to 1 with water and mix this with cement to give a thin paste. Apply this to the floor and this will give a good base for you to tile.
