Trying to learn from my mistakes here......

Thanks all

With the last few tiles I basically used the flat part of the trowel to give myself a flat bed then applied more adhesive with the ribbed part.

I think my problem was that I was trying to apply too much adhesive at once. The last wetroom I did I ended up using profix rapid set SPF to smooth out the rough concrete, then when this had gone off I then applied more SPF to lay the former down. That actually worked really well.

I guess for large areas, you could use a straight edge with a level on top to level out the adhesive, let it go off for about an hour then apply more adhesive on top and lay the tiles as normal.

You need to find out where the "high point" in you floor is and start there!, you can add material but you cant really take away

I learnt this the hard away. grinding 2mm off the back of 600 x 300 porcelain was not fun.
