[grayd6]

hello to all, just priced first job this morning (15 mtr2)bathroom after doing 4 day course at nett .need a bit of advice .all the old tiles have been removed and the walls are not to bad there is just some of the old adhesive on the walls. although it looks ok to tile on to do i need to prime the surface first.i think i do .
also got floor to do less than 3mtr2.there is vinyl tiles down and they are solid on to a concrete floor . am i right in saying i can tile over them .and i can use rapid set and also that i should prime as well...

any advice greatfully recieved..
cheers, davey gray........

Priming won't hurt though it is not always necessary. DH primes everything!!

I think for the floor you must ensure the current tiles are SOLID and rough them up and again prime. I think the common substance to use is BAL Bond though I have not had to tile a floor with vinyl tiles already down, so I am stabbing a guess here.

If there is any suspicion the the vinyl tiles may be insecure, you would be wise to remove them.

grumpy is right..prime those vinyl tiles with bal bond sbr and tile within 24 hrs of priming them....no need to rough them up..you can prime the walls to dust proof them as wel....good luck....

Hi lads, not logged in for while, but just seen this question and got me thinking what do other tilers prime with?
I use to use PVA but then decided i didnt like it as thought it didnt give onough strength to the glue. Now use the acrylic primer from granfix and feels much better. Tiles seem to stick much better with it. And it smells like sweet chewing gum!
just wondered what you guys thought about PVA or other primers, and what not to use etc?
cheers
