Anyway, I'm carrying on with the mix it yourself stuff. Seems a bit
gritty by the time it's tick enough not to "slump" (as the
instructions suggest). Going to have a google to see what consistency
it's supposed to be!


That's partly why I use ready mixed. These adhesives should ideally be
whipped up like a cake mix, which is beyond the home user.
I think the consistency should be the same as a ready mixed filler or
plaster from a tub i.e. you should be able to stand a screwdriver in it.
Not a very scientific way to describe viscosity :-)
