Hi I am looking for some help. I am ordering a TUFF2 grp base 1300 x 820 with WP10 tanking. The floor is wooden boards would I need a durabase CI uncoupling membrane as well.

Thanks in advance

I would in a wetroom.. but you might also need some prep work..

What sort of prep work would be needed? Do the floor boards need reinforcing?

Thanks Reuben

They will need extra noggings and make sure no deflection and then i would over board with hardibacker 250 to give a better substrate for the adhesive to bond to..

Then water proof it with the Ci..
