Hi Guys, I'm fitting some large tiles. The wall tiles are 33cm x 100cm. Am I right in thinking a 6mm square notched trowel will be ok for these? The floor tiles are 44cm x 66cm (porcelain) and I was thinking 10mm round notched trowel. Also, wasn't sure whether to go with butech adhesive or toppfix. I'll be using bagged adhesive for walls and floors due to tile size etc. Has anyone got any other tips or suggestions?
