A couple of weeks ago or so there was a discussion on the group about the Fugi sealant-finishing tool.
Against the day that SWMBO's ensuite shower needed re-sealing, I ordered a Fugi via eBay, which duly arrived.
The resealing exercise was brought forward when SWMBO reported that some of the lowest tiles in the shower, which are a dark yellow, had turned slightly darker in random places, suggesting that water had penetrated past the sealant and was wicking up the tiles behind the glaze.
So, removing as much old sealant as possible, and having applied waterproof grout to the lowest run of tiles, I set about the resealing. Now I have to tell you now that I'm the world's worst sealant-gun operative, and there's not a lot of room in this shower cubicle, so things weren't looking good.
However, I do follow this group and kept in mind what I'd read about applying sealant, so put a good bead of it in approved fashion along the appropriate two edges of the shower.
Then came the exercise with the Fugi, using the 8mm right-angle.
It worked like a charm. The resulting finish is easily a quantum-leap over my usual standards of workmanship.
Consequently, I'm very grateful to the group for the advice that was offered, even if it wasn't acknowledged at the time.
