I think 2buck made a good point!I don't know, makes a bit of sense.
With paper tape, things will crack, but it takes longer for the crack to work its way through the paper. I don't know how many guys have removed a tape, and seen the mud that has entered the crack or gap in a bevell, remain hidden behind the paper. Well with the "M" stuff, there is no place for the cracking to remain hidden behind.
So with this product, it's not bragging it's strong, that it's going to hold the house together, it's bragging point is it's FLEXIBLE ..!!!!!!
So where do cracks start, on the surface or underneath. If the product moves underneath, and does not crack, then there should be no crack to work it's way to the surface.
I would be more interested in it's pre-filling properties :thumbup:
