I've to tile an area that has altro vinyl over a chipboard subfloor. I had initially intended to tile straight onto the altro as it's a relatively clean, uniform surface but was advised by one person to remove the altro, in case it 'came up'.
Well, I had to remove a 600x300mm section in a doorway anyway but ending up having to chisel it up which took around 30 mins! This stuff ain't going anywhere...and there's about 20sqm so I'm intending just leaving it down.
The question is how to proceed - tile straight onto it? Or should I put down backer board first? If backer board, should I use tile adhesive or screws for that?
Thanks in advance.
