Thank youI personally use a smaller width Schmox clip with a spacer. i.e. a 1.5mm clip used in conjunction with a 2mm spacer.
If you just use the clip you stand a greater chance of chipping a tile when you kick or hammer the clip away, as sometimes tile adhesive gets caught up in the clip.
So to answer your question. Yes, you can use a 4mm spacer with your 1.5mm clip.
Thank you
4mm is quite a wide joint line!
I’d go with 2mm. Definitely not 4.Hi,
Thanks for input. They are 900 porcelain plank floor tiles do you think 3mm would be better.
