Looking for a bit of advice on what size of trowel to use for a mosaic laid on the floor. The individual tiles are 50mm square, and porcelain (if that has any bearing on it). The floor is perfectly flat, although it is plywood. I lifted the original floorboards, braced all the joists (450mm centres), fitted noggins to support all the cut edges, and laid 25mm WBP ply screwed with Spax screws at 150mm centres. I also primed the underside and cut faces of the ply.
I'm worried about getting loads of adhesive up through the gaps in the mosaic (mesh backed) so advice on trowel size appreciated. I'm planning to use Mapei Keraflex Slowset.
Final query - I don't have to prime the face of the ply being tiled as far as I understand, is that right?
Cheers,
Richard
