tiling on plywood: how to deal with the 3mm gap: plywood joints

[Mirjam]

Dear all,

We want to tile on suspended plywood. There where two plywood sheets meet needs to be a 3mm gap according to what I read online. But how can I prepare this gap for tiling, so that it still stays flexible and can be tiled upon? Fill it up with sealant etc.???? (Porcelan Tiles on BAL PTB Flexible Grey on 25mm Hardwood Plywood Board)

Thank you very much,
Alexander.

These joints can be filled with adhesive as you tile the floor. Just make sure the floor is screwed down nice and tight

The gap is to allow boards to expand so that they do not heave against each other... nothing required to fill it other than adhesive.

Yes, u r right cam_low. We are in fact international spies, trying to blackmail the tilersforum. But now that you found it out.... .
Thank you very much for your advice (all the serious ones).

Personally i would fill the expansion gaps with a good quality Silicon!

I would be laying Ditra 25 before tiling, more expence I know, but better than cracked floors!
