I did similar test with same adhesive just directly on wunda insulation panel...you need a hammer to take it off...solid as a rock. It looks like this ren screed so smooth or greasy that didnt stick, not penetrating into surface just sits on it. Better I avoided it doingYour test is still unfair as to amount of force you are applying to a small area ,
See now I kept away from wundaboard advice as I have no experience in itThe eco prime grip is supposed to go onto the top of the wundafloor boards prior to tiling.
You can stick the underside of the wundaboards down to the levelling compound with any c2 adhesive.
Are you a tiler or a DIYer, if you do not mind me asking as Wundafloor will only guarntee the floor using their tested method which is using Mapei adhesives and primers.
I have just tiled one before Xmas and it was a total **** up with the people who laid it.
One more point - you will need a crack mat on top of the wunda boards too as it is Travertine that you are fixing.
Good job I know what I am doing!!!
