Hi I’m currently looking to tile my kitchen however as it’s been extended it has 2 different screeds , one very grey and new and one 27 years old and looks more reddish however I’m told both are screed. I want to tile onto both screeds however do I need an acrylic primer to be applied first, or can I just use tile adhesive. A big concern for me as can’t seem to find an answer - thanks

OP,
Use a cheap SBR primer such as: Everbuild 503 SBR Bond or similar.
Use a powdered thinset adhesive.
Are both screeds at one level? Has the join between the screeds been given special attention?

Thank you
I have some Bostick Cempolay universal primer purchased through Screwfix and hopefully can use that now
The join as in the picture has the new screed overlapping the old screed 2 to 3mm
A professional tiler dropped by late last night and after using a long spirit level told me the surfaces where flat and said he didn’t need self leveller to be used and wasn’t worried by the join as the adhesive would compensate
Thanks

It might be advisable to use a decoupling matt.

I wouldnt tile straight over a joint of very old and new screed
you are asking for cracks -Opps above has the correct answer
how long has the new screed been laid, it will need about 75 days to dry if its 65mm thick....not so important with a decoupling mat

Thank you all some excellent guidance
The new screed has been down about 30 days and about 40-50mm deep
The builder told me to consider self level and feather it across the joint
On the old screed I did notice a crack near the outside door which had as it happens cracked the tiles above it
Wonder if there is a very light fibre glass matting that I can apply across the joint and the screed crack too
