can you plaster over old tiles?

wolfehouse

my kitchen is tiled from floor to ceiling
in tiles dating back to the 70s


it would be a big job to remove and replaster
so I was wondering if there are other solutions.


boarding over would require taking down the cabinets and building up the door frames etc. so I was wondering if it is possible to
simply plaster right over some of the tiles?

MonsieurFrugal

as long as they're fixed solidly to the wall then yes

Thistle bond it and then skim

But the job would be done right! TBH, an SDS drill with the correct attachment will remove tiles like a knife through butter then base coat and skim of plaster should see the job done in two days.

I agree, they need hacking off.

It's a kitchen, it will get subjected to a fair amount of moisture,
If this gets into the plaster it will reactivate any PVA adhesive used. The plaster will always be at risk of failing.

Plastering over tiles ? that would be a bodge and half !

Far better hacking off and reskim or dry line

If you don't want to remove the cupboards and the existing tiles are firmly fixed you could always tile over the existing tiles.

Nothing wrong with that, except, there is a limit to the weight per sq metre you can expect any plaster or adhesive to take.

What is important is what are the original tiles fixed to???, Do you know.

Worst possible scenario is this;

The tiles are at present well adhered to the gloss paint that was applied to the original walls, they used 150 x 150 chicken tiles in ceramic.
You overlay more modern tiles, maybe bigger and heavier, porcelain even.

You are going to be over the limit of the plasterboard, plaster, paint or adhesive.

There are max weight recommendation charts for every type of wall, tiles come with a weight per/sq/mtr on the pack.


Research further if you go this way.:A:A

PVA won't work as it wouldn't dry on the tile surface

Have you never used bond it ?? Once dry its pretty impossible to remove. We have done plenty of pub toilets with this stuff and no failures yet.

Have to say, "No, I haven't", but would the OP know what the bloke had used or then again what to buy? Plus, how do they know how the 1st layer was fixed?

Do it if you wish op, 4sqr mtrs of tiles on your head is about 125kgs

Not good

Andyhop is right .. I don't know if 50.00 quid is worth the spend to you as 1 tup of thistle bond it cost that much from travis perkins etc . you wont need it all, though just mix and don't delude with water, apply to the sand , let it dry 24 hours then plaster or tile as normal.. if it falls I ll buy you a whole new kitchen.... these who don't know should not just scare the fella with the ''do it right /remove then replaster .
