What to use to fix slate tiles behind stove?

[beatnik]

Should we use fire cement or just regular cement to fix the slate tiles to the aquapanel around our Squirrel stove?

 

Or is something else better?

 

Thanks

Thanks!

 

We already have the fire cement but were worried that it wouldn't go off. I suppose we can just dig out the heat gun so that it goes off.

Me too - of the flexible variety.

concur.

 

we should resolve all technical issues by taking a referendum ................

Fire Cement - fine unless it gets wet (leaks from back boiler?)

Tile Cement - fine even for slate

Contact adhesive - normally used on showers (waterproof!)

I used ordinary tile cement back in the summer when I fitted the stove.

 

Some of the tiles are now starting to come loose with the heat

Flexible tile adhesive (the correct one for floor or wall tiles). Fire cement is way to brittle and tile adhesive is heat resistant enough for the job.

 

If you're tiling over Masterboard or Aquaboard you need to treat the surface with a coat of PVA or similar (some tile outlets sell specialist stuff), prior to tiling because these boards are very porus and will suck out the moisture from the adhesive before it has gone off and the adhesion will not last. This could be why some people experience tiles coming off.

Oops - didn't do that. No probs so far but I suppose the tiles have only been on there three months. Hope they don't start plopping off. They feel very secure at the moment.

We tried the fire cement but it was like tiling to thick dough and we only did the bottom bit. So we'll use flexible tile adhesive that we have leftover from the bathroom for the walls.

 

Now, what exactly is PVA?

 

Thanks

"No More Nails" type adhesive personally. Straight on to Superlux, nearly 4 years now and fine. BTW we used silicon to fix the bathroom ones.

I used normal tile adhesive which was fine for the horizontal surfaces, but almost all the vertical ones fell off, due to the vibration and movement of the boat I guess. I reset them with silicon rtv and that has worked well. The red high temperature stuff might be good near the stove. Normal grout with the flexible additive worked pretty good except at the interface of the horizontal and vetical surfaces. Extra movement here caused it to crack so I replaced it using clear rtv mixed with the grout powder which gave it about the right colour.

Polyvinyl Acetate. http://upload.wikimedia.org/wikipedia/en/6...ate_formula.png

 

Is that any clearer?

 

Just go to a tile shop and ask for something to prime a porus surface before tiling.

 

Edit: I've never actually seen Aquaboard, but if it's anything like Masterboard (grey, powdery, porus stuff) then you should prime it first.
