Sticking down exterior slate tile

[Lobster]

A few months ago I laid some slate tiles outside on a mortar bed, and unfortunately one has lifted. Underneath the mortar bed is completely flat and undamaged, and I'd like to be able to just stick the tile back down with something, rather than hack out the old mortar (no doubt having to disturb the surrounding tiles too) and replace it - with the risk it'll probably lift again anyway?

Any thoughts as to suitable adhesive? Or is it Portland Time?

Thanks David

I'd try with a 'No More Nails' type adhesive. A solvent based one is probably better outside.

Did this when a slate tile in my dads conservatory came loose. It worked fine there. I don't know how it would hold up ouside, but probably last while. If it comes loose again in couple of years well, you haven't lost anything.

Or epoxy.

Dare I suggest car body filler?

Thanks for the replies. I'd considered both epoxy and No Nails as possibilities, I must admit: which do we think would be likely to last longer (or any other suggestions?)?

I appreciate either of these is a bit of a bodge, but as Chris says, if it lasts a couple of years (by which time I'll know if I have a general problem with other tiles) that's fine by me!

Leadmate might be worth a try.

stuff, sticks like the proverbial to a blanket, frostproof and good for '25 years' whatever that means. still a bodge, tho.

Bodged one, only temp of course!, with silicone sealer on a friends house eight odd years ago, still there and held in place fine:))

What's the problem in doing it properly, with a pourable grout mix of water and neat cement ?

[Lobster]

Well OK... I've never heard of using water and neat cement; is that a tried and tested method for a job like this?

Absolutely. Mix water and cement to make a grout the consistency of custard - you only need half a cupful for one tile :) It's the proper way to lay quarry tiles, using a watering can to pour the grout into the joints. Leave it 48 hours or more to set before walking on it and it will be stuck rock hard for ever.

Car body filler or epoxy :)
