Jakoboard thicknesses

[Blunt Tool]

I’ve done a kitchen floor 600x600x10mm porcelain tiles approx 24 square metres the Gifa boards were installed onto joists with extra noggins even tho it was T&G. The kitchen was installed bar the island, joints fibre taped and filled with fast set flexi. Primed, tiles installed and grouted. That was 3 years ago I think and I’ve been back twice to do a bathroom and en suite. The kitchen floor is still as good as the day it was installed and would recommend to any customer who was going to start from scratch. Trust it more than all the layers needed usually and keeps height uniformed thru house

I suppose once you weigh it all up- the ply, the overboarding, the labour etc vs the thick cement boards, I don’t think the cost would be all that different.

No membrane on top of the Gifa though?

Think if it had been 24 metres of stone I would have put Mapei wp200 mat down, normal size bathroom stone right onto Gifa yes.

Sounds sensible. Yes I agree about the stone. Porc doesn’t seem like it needs it but I suppose you can never be too careful.

All stone have natural holes, fissures/cracks, some parts of their composite is very hard other parts very deceiving and brittle, no two the same. That’s why a thin crack mat just gives that extra protection over a long stretch of floor. It’s more to give the stone a bit of relief, let it breathe
