hi can anyone point me to the right direction as im looking to tile my kitchen floor which had vinyle tiles which i ripped out and now left with a bitumen base floor. i have a couple of questions,

1) do i need to prime the floor? is this a must do?
2) would it be ok to use mapei proflex adhesive from tile giant £15 a 20kg bag?
3) which other adhesive can i use? whats the differnce between something like wickes flexible adhesive which is at £13 for 25kg bag?

thanks in advance

Is this bitumen adhesive left or an actual bitumen pour..?

hi i think its bitumen pour,

You think..?

Best to dig into the substrate and find out how far this blackness goes,,

so if it is deep wouldnt i be able to tile on it?

Yes you can, i want to establish whether you have a bitumen substrate or just a bitumen glue.
