phat trev Posted October 17, 2011 Share Posted October 17, 2011 I have mixed some home made filler using humbrol liquid glue and sprue off cuts to fill some small surface gaps in a wing. how long does a small application of this take to cure before can start sanding down the area? cheers Link to comment Share on other sites More sharing options...

Last time I did this it was 2 days before I could work on it properly - I overfilled slightly & used the tip of a craft knife on the overfilled area to gauge how hard/set it was.

Last time I did this it was 2 days before I could work on it properly - I overfilled slightly & used the tip of a craft knife on the overfilled area to gauge how hard/set it was. it is quite thick (close to marmite viscosity) well its been 6 hours now since i applyed the mixture and after proding the area with a blade (good advise) the surface has not hardened yet, think I will wait until the morning. thanks for the advise.
