Tiling over old terrazzo porch floor

[Coop5]

Hi guys,

Literally just lifted the floor tiles of my porch floor (only about 2sqm 1920’s house) underneath is a kind of marble looking resin.

Google tells me this could be terrazzo!?

Anyway I need to level this and then tile.

Can anyone give me some advice here. Is it possible to level with a certain primer and leveller rather than digging it out ? Or possibly an adhesive and backer board approach ?

I do not want my new tiles to be popping off as they haven’t adhered properly.

Thanks all

sbr type primer will be fine.

Cheers mate,

Sbr down then 24hrs later I have used mapei self leveller.

Mixed to correct quantity and poured. Dried ok but now have hairline cracks in. Nothing appears to feel loose or hollow, can sbr this again and lay another 5mm or so ?


Cheers
