How to cap & cove: installing vinyl flooring with coving 

Butterfly corners used in hospitals a lot

Same here - I’ve been fitting coved vinyl (in various situations) for 22 years now… As much as I find the above style of fitting ‘interesting’, it’s FAR removed from the way that I fit/weld commercial vinyl, especially the internal mitres - it literally makes zero sense to cut that material out…only to immediately add it straight back in again and forcing yourself into having to spend a load more time on fitting something that needn’t exist in the first place. And then there’s the extra welding (again, for no reason at all)…???!! Externals’ are naturally required, we know that, so I totally understand why this is used on that part, but other than that you’re basically cutting bits out and adding them back in again presumably for the sake of wasting time and creating potential weak points in a wet area 😮😮

The internals aren’t an added piece. When he’s split the internal he’s just wrapped that triangle your left with around the corner

Butterfly corners. I’ve done jobs where they specified butterfly corners. Not a fan of

Butterfly's they're way stronger and more durable than boots. They'll last way longer. You'll eventually run into a job that requires them. They're pretty damn easy to do once you get a few under your belt.

Contact adhesive like evostick

Paper pattern? With boots right
