Siliconing before grouting

[One Day]

@impish what is your reason and what is your usual size of Silicon profile

I've never really given it a lot of thought. Cleaner, less dust and contamination I suppose. Also avoids grout getting in my internal corners. I try and keep the joint as small as possible, using fugi tools - 4,5,6mm depends how good my cuts are!

I've done it a few times....but imo you don't get the same level of finish as doing it after.

Same for me
