Okay, Im erring on the adjustable pedastel system rather than porcelquick as it doesn't involve cement and adhesive. However, to create the inside & outside seamless look I would need to grout externally. I assume I do as otherwise the external tiles without grout would look like an unfinished job when compared to the same tiles internally with grout, unless anyone else would disagree.
I assume you can use the grout backing rod with the adped sysem too as with the porcelquick system??
