Looks great that Wes. I like the attachment to keep it straight on tiles I have this set. Works well. http://www.screwfix.com/p/no-nonsense-smoothing-tools-straight-joints/92313
That's not the 5 piece set with the guide for going against tiles . i just ordered from eBay plumbworld 11.97 for the kit
Looks like a similar design Daz. They don't look like they have the guide but it's not the end of the world..
I use it on bathroom vinyls/cushion floors mainly. My customers prefer it to be sealed so its water tight (ish)
I use it round my LVT jobs when customers don't want beading. The thicker the better. They like the thumb prints in the corners too.
