Advice Needed?

[HardTarget]

Hope someone can advise me on the best way to go about two tiling jobs I need to do at home. First I want to tile over an old 1930's quarry tiled kitchen floor. I don’t want to remove it, which I know would be the proper way to guarantee a perfect job; instead I am hoping I can tile over it? I have read various ways, but confused even more. The floor is solid and dry and if I'm honest a shame to tile over, but the wife wants a modern porcelain tile. I have read a lot about using an uncoupling membrane called Schluter Ditra. Would this be overkill? If I was to use this what adhesives would I need to fix the ditra to the quarry tile and also the porcelain on top of the ditra? Do I need to prime the quarry tiles before laying the tiles?


The second job I need to tile the bathroom, which I have already taken up all the old floorboards and have replace with 18mm marine ply, which I had left over from another job. Basically the same questions as the quarry tiled floor. Do I need to use anything between the ply floor and tiles and if so what would you guys recommend including adhesives and any primers? Really appreciate any advice guys as I have posted a similar post elsewhere and not a single reply L

If your quarries are fine and have no cracks then perhaps tile as is.

Have you pulled up the odd one to test how they're fixed?

The bathroom I'd perhaps use a tile backer board. Lads might correct me.

Hi Dan, there is one corner that the plumber drilled to get his pipes through and it lifted a tile and from what I could see it was some sort of black morta. The other tiles seem solid when tapped no hollow sounds and no cracks. Shame really to tile over

Personally I'd refurb and restore them but if the mrs is involved it's not happening we may as well all give up that one.

Got any pictures?

Not sure if I have done the pictures right?

There's been a few changes there with pebble dashing on the inside...

 

[Dan]

They don't look half bad.
Appears to have been a repair. What's that darker tile?

Spotted that. Looks like a crack to the right too. Seems to go through two tiles which mean perhaps the substrate has caused it. It might be worth investigating that.

I clocked that. I guess a lean-to come out-house attachment. Slabbed floor too.

It’s the original floor I think? They have done some sort of alteration to the kitchen side door entrance step in the past.

I have done a total refurb on the house and would love to keep the tiles, but she who must be obeyed wants new porcelain tiles she has seen at topps tiles.

The lads at work reckon I can just go over them using a flexible adhesive, but I’m worried about problems with movement or possibly damp and don’t mind going the extra if it helps, but so many ways and adhesives it’s confusing to say the least.

The black underneath could be a bitumen DPM.
As for the tiles , I'd personalall clean them to remove any old sealer and cleaning products that have built up over the yrs.

Then I'd fix the likes of Ditra over the floor , this prevents stress from the old floor transferring to the new floor and the old tiles will expand at a different rate and could cause issues.

But only you can decide if the old floor is suitable to tile over as we cannot see what you do.

Yeah spot on It's a lean-to garage to the side of the house.

You need to be 100% sure they're fixed well so try get a few up. Doesn't matter if you make a mess if you're tiling it anyway.

I'd then soapy-water them. Dry them. Prime them. And tile them with a single-part flexible adhesive with no ditra. There's not going to be movement in those. They're very well settled I'd have thought.

Using a flexible adhesive means you'll take into account any lateral expansion and retraction differences in the two tiles. Which I'd assume wouldn't be much. Porcelain wont move much. And decades old quarries wouldn't either. Even fired at thousands of degrees quarries don't expand much.

Sorry was writing as Ditra Dave was writing then lol

He's got shares in that stuff I think.
