Silicon being used on corner joints. Should the lithofin grout protector be applied before siliconing the corner joints, or after, i.e. does lithofin make any difference to adherence of silicon, etc. ? Thanks, Simon.
I have silicone sealant (the Dow Corning 785 stuff) applied over the top of lithofin in my shower, and it doesn't seem to have compromised the quality of the seal.

I applied the lithothin after the silicone (and siliconed the corner joints as you describe)...
No adverse problems that I have noticed.
