What the previous guy did

[LEH]

As you've all been very helpful so far, I thought I'd 'repay' you by sharing a few pics of what the previous owner had done to the bathroom I'm now ripping out...

I know you're all fans of a bit of dot and dab...

Maybe needs a bit more coverage though for fire damaged plasterboard? 😀

When I saw signs of backerboard, I thought he had done something right...

And what do you do when you run out of said backerboard?

 

[Flintstone]

Lovely!

 

[Qwerty]

Wow!

 

[kevsalt]

oooh nice ...love that slither of marmox ..ace

And this is why you should not tile on tiles!

 

[Brian the Tile]

Nothing wrong with tile on tile if the right materials are used and the person doing the job know what they are doing

I think the point John is making is that you're relying on what the other person has done, so unless your 'right materials' include a crystal ball then i'd be agreeing with John

 

[Perry]

Yes but most don't IMO.

Dont think you need a crystal ball to know whether the tiles are good enough to be tiled over common sence should suffice

ok Brian. Tell me how you'd do it?

 

[hmtiling]

i.e. right materials

Check the tiles to be tiled over are solid enough and away you go with a good quality powder addy

no primer Brian?

 

[Flintstone]

The thing is, Brian. All you can do is tap them, that doesn’t really tell you anything, they might be stuck with ready mixed onto wall paper

 

[Brian the Tile]

Its a bit like being told you cant tile on ply

 

[Brian the Tile]

I think its up to the individual im quite confident to tile on tile depending on the circumstances and never had a problem

 

[hmtiling]

Its a bit like being told you cant tile on ply

would you prime? and what if they're well fixed on a skimmed wall? how would you know? what if it's already been tiled twice?

 

[Perry]

As I said most people don't know what they are doing. So they look on this site and think It may be correct even when its not.

if people dont know what they are doing then its best to get someone who does,like i said ive done it numerous times without any problems,ive heard it many times of customers that someone has told them it cant be done

 

[Brian the Tile]

I have no crystal ball i just know when im confident in what i am doing or believe me i wouldnt attemt it

a hunch you say?

 

[Brian the Tile]

???

how can you just know Brian, unless you did the first layer?
Also, if you're doing it again you may want to use a mechanical grip primer first http://www.mapei.com/public/CA/products/6324_ECO_Prim_Grip_EN_lr.pdf

 

[Perry]

I have tiled thousands of mtrs over tiles with the right materials. But I wouldnt suggest it to the average person on this site.

Sounds very good stuff but not if the tiles are are not fit to be tiled over

Brian!?
I’m all for tilers taking their own risks when they deem necessary ...... but if you are tiling over tile without having heard of prim grip then I’m sorry, you are endangering lives - simple as.!
If you sleep at night tiling over tile that’s your bag, if you sleep at night tiling over tile without the appropriate materials that’s another thing!!

And before you come back with - I’ve done it loads times with no issues.
You have been lucky and some of your jobs may be one slam of a door away from disaster.!

Please stop and learn from the people who are telling you it’s not a good practice and don’t risk the life of someone in a bath because it’ll save you a day prepping properly

weight limits when tiling a wall... - https://www.tilersforums.com/threads/weight-limits-when-tiling-a-wall.4632/
Ten years old Brian...not much changed 😉

 

[Slippery]

The last bathroom I did was alreadty tiled and the customer asked if I would tile over the top, (they were happy for me to do that!) but I didn't want to take a chance.
Turns out, there were already two layers of tile, the second was well stuck to the first but the first layer came off in sheets, there was more grout stuck to the plastered walls than adhesive, and there wasn't much of that!

 

[Flintstone]

I would never ever tile on existing walls tiles! Floor tiles, yes under certain circumstances but I would rather not

 

[Dumbo]

I Was tiling a floor in a house whilst a plumber was ripping out a bathroom and he was coming out with 3 layers of tiles . Wondered why that window didn't let in much light .
