SMC Shower Tray

[waheed357]

Hi,

I need some advice laying my shower tray. Its a light weight low profile SMC shower tray. Some what flexible too. Subfloor is 18mm chipboard that im going to put 6mm tile backing board on for the tray. There isn't much in the instructions and just say silicon the floor.
The floor is not perfectly level, maybe out by 1 or 2mm in some places. Would using a lot of CT1 for example and using weights level and set the tray or should I use something like a tile adhesive instead to make sure its level? The back is not flat like a stone shower tray as can be seen in the photo. Thanks.

Flexible floor tile adhesive for me.

I believe they recommend a flexible adhesive for setting down moulded trays. The sub floor does need to be level though so the tray sits flat on it and all the adhesive is doing is setting it down. The adhesive shouldn't be used to level out the tray, given the slightly flexible nature of the material that the tray's made from.
