floor tiles and marley floor tiles?

[woodie]

a 'big mutt' is a heavy duty floor scraper which weighs a bit but it's well worth the effort. i bought mine either from screwfix or machinemart can't remember but it's a beast :santa_cheesy: and marley tiles are a pain in the a**e they become very brittle and come up in pieces

When you remove the tiles, you'll need to remove the bitumen too.

You must remove the marley tiles. then the belt an brace way is to give the floor a good clean and put a slurry prime. A slurry prime should consist of 1 part adhasive, 1 part water and 1 part acrylic primer. mix it all together, apply to floor and allow to dry. then fix your tiles as normal.

I hope this helps.

whats adhasive,i cant spell it also so i call it addy!

I have just removed some vinyl floor tiles and been left with acrid smelling bitumen (I assume) adhesive. The tile shop guy (I've read the comments about their advice!) told me it would take ages to remove and it was ok to simply tile over the top.
The floor is concrete underneath, I have tried to remove it with a floor scraper but it is taking ages (4m x 4m area)
Question is do I have to remove it? (as per PI quote above) and if so are there any chemical solutions to help lift it? (its been down donkeys years)
Many thanks
