Which decoupler for outside????

[Alex Reed]

Hi guys.

Got around 200m2 of 800x800 porcelain to do on an outside area that will follow on from 200m2 of inside floor tiling. Inside will be BAL rapid matt stuck with anhyfix then tiled with SPF Rapid. Can I use the same method outside.???? Is the matting and glue gonna be suitable for it???? If not what will be. Flowscreed inside. Sanded and primer. Outside possibly sand and cement screed. Not sure yet. All input gladly received.... Thanks.

Ditra Drain by Schluter is an excellent option for this, it’s a decoupler and drainage system in one.

As above . I have used it . It is a good product . Also you need to make sure your ext slab has a fall to allow water to drain .
