I remember some time ago using a filler bought from the Dulux shop in town and it had the consistency of ice cream. Great filler, very light, no shrinkage and non sandable. I think there were two kinds, one being Red Devil OneTime and I forget the other. Now I don't know if it was the RD I am looking for or the one I can't remember. Time to decorate again and fill some small cracks. Can anyone jog my memory please?
Best filler I've been using is 'Toupret Interior Filler', a very fine filler, mixes to a consistency of double cream, sands easily & doesn't shrink. Only availble from SF's competitors.
