Wondertex ultra light filler

[Gooseone]

Hi fellows ( i pressume )
I work in the Netherlands and used to use this stuff , i mostly hotmud by hand and i like
the stuff for the way i can "clay" with it sort of speak.
It is terrible stuff do anything other then mud a joint first coat , but for that single purpose i regarded it quite highly.
The quality of the batches always varied , but recently it started not hardening out fully.
( Like the moist in it takes a few days to eveporate completely..or something )
Which led to cracking especially when skimming with Prospray and spraypainting.
I usually use fibatape so that doesn't help , but i was wondering , seeing it is a UK manufactured product and not that much used here in Holland if there are more experiences with this stuff not being up to par on these forums.

Thx in advance for replies.

I used it for a while and didn't like the way it 'rolled up' when you tried to blend it in to an earlier batch.

It is indead worthless for doing anything other then applying a first coat / mud a joint , and even then you have to not wait to long are be to laidback because it rolls up already.
I do kinda miss using it though
