Tiling a fibre glass shower tray

[ghceramics]

Hi this is my 1st post so please be gentle...haha..

Im quoting a wet room to be tiled in 100 x 200mm travertine tiles..The walls are aqua boarded and tanking to all corners. The shower tray is made of fibre glass and already has the `falls` created within it.. Obviously im using a white powdered adhesive for the trav..will i get away with using a single part flexible or should i use a 2 part flexible adhesive? Im going to use coarse sand paper on the tray prior to tiling to give it a key...all comments and views welcome..

regards

Garry

when you say 'tray'.... do you mean actual shower tray or wetroom floor 'former'??
if you mean fibreglass shower tray then i don't see how this is going to work...?? might just be me but if i was doing the wetroom floor it would be either, a formed floor, tanked and tiled...or a tanked and tiled room with a low profile stone resin tray in the floor...IMHO...

Cement based adhesive to fibreglass/GRP is very difficult substrate to fix to even if the adhesive is modified with an admix adhesion isn't that good in wet conditions.

Roughen the surface lightly and fix in epoxy adhesive as this type of adhseive will bond very well given the substrate type and service conditions

Its a white Impey 1800 x 900 22mm thick wet room former

dont they usually tank right over the tray? had the pleasure of those impey ones, the whole floor including the tray is covered in the tilesafe system which you then tile straight onto. should this be the case here?

 

[Time's Ran Out]

Yes Turnip you are right!
Impey trays are covered with the tile safe membrane that adheres to its surface.
And when in a wet room the walls are also covered in the same product.
Have done a few over the last couple of years and its a good system -but time consumming and labour intensive.
Apart from the epoxy adhesive as already advised - I don't know of another product that you could use to fix tiles to this type of surface.

John,,are you on about the self adhesive membrane here..?...

Give it a rub down with some sand paper to get a key for the adhesive.. Using a powdered flexi adhesive apply around 3/4mm of adhesive over former with serrated troweland apply membrane (Dura-wp / ditra) pushing back to clear out any air bubbles. If a wood floor them membrane can be extended to whole room applied the same way.

If using tilesafe apply as above without the adhesive.


Hope this helps
