First Job - tiling over tiles & taking up ceramic tiles of concrete floor

[daddy30]

Just got a phone call for my first job.

It involves tiling over tiles in a Kitchen, the customer has just had a brand new kitchen fitted and didnt take the existing tiles of so needs me to tile over the existing tiles. I've told him its better to take off existing tiles but he doesnt want this. Should I turn this job down or is it okay to tile over tiles?

Also he wants floor tiled and I would need to take up ceramic tiles of a concrete floor. Will this be easy enough to do? Will the adhesive come off easily?

thanks for your help

I do try to avoid tiling over tile usually, but you can. Make sure you clean them well first,and use a bagged adhesive not ready mixed, and theres no need to prime. Also make sure there is nothing in the way that will stop you,ie any pipe work or door architrave that will have tiles protruding ect. As for removig the flor tiles, i use a sds hammer drill with a cranked head chisel, makes lie a bit easier, then put a slc over it to make the floor nice and level for tling. Make sure you cover every thing with dust sheets as there will be quite a bit of dust and tille splinters flying about.

hi dad:smilewinkgrin: you can tile over tiles although as phil says check nothing is going to have get in the way of your cuts..you will ned longer screw for the sockets you can get them from b and q.

i would also advise you to buy an sds drill if your get this job and buy a tile removing head for it ,,you will have the floor up so much easier with this if you use a bolster and hammer you will make a very hard job for yourself...good luck

You dont need to prime???? What? Bond all surfaces all the time, You should have built the cost of hiring an SDS for the floor tiles into your estimate, Even if you own one you should be charging accordingly,

i dont think hes been to see the job yet diamond still at the getting advice stage so he can still build that cost in mate.

p.s.s if its your first job remember and be confident and positive when you go in to price let the customer see you are confident about the work mate

I was replying to him being told he does not need to prime tiled walls prior to fixing?
of course he does, what are the tiles like that are on the walls ? if any are loose or cracked you need to try and get the customer to see that its best to get them off, "pay cheap, pay twice"

Hi GRR, I use acrylic on everything, if its fixed to a wall its getting bonded,

kitchen tiles will always have ingrained dirts/ fats etc that should be cleaned off with sugar soap or similar, bonding is better than not bonding, why leave it out?

:yes::yes::yes:

I'm also putting ceramic tiles on ply using PCI tile fast 6, should I prime the ply before adhesive?

 

[diamondtiling]

Yes you should matey, what thickness is the ply, where is it situated??

I'v just spoke to mapei technical,and they said if you are tiling onto ceramic tiles then there is no need to prime, as long as you use the right addy. ie mapei kera quick

 

[diamondtiling]

Have you been ringing them for the last 3 hours

:yes::yes::yes:

 

[poynton phil]

No, iv been upstairs painting the bathroom, while i'v got the time, just came down for a cuppa and read the posts.Surley if you put primer on a tiled wall it would'nt soak into the surface, but just run down the wall?

 

[diamondtiling]

So what would the addy stick to? Acrylic bonds all surfaces (most), the grout in the old tiles would be bonded, My opinion is apply to all surfaces, did mapei really say dont bond a ceramic surface? I would use full strength acrylic on a ceramic wall
