Kerapoxy 3mm groutlines!
That's good gear to use, make sure the tubs are kept warm prior to use as it makes it a lot easier to use, iirc the coverage out of a tub isn't great, but we had 5mm joints, you'll need lots of clean water, a few pads and sponges, it really won't be a bad job, good luck, just use one tub at a time,both apply it and both wash off, you'll have it done in no time, the last job I used it on we had about 50m2 on the ceiling alone, mid June in the heat, ouch, some pictures in my albums under Chiswick house,
