Reply To: Does matt Varnish go off? – Airbrush always getting blocked

I’ve had issues with Vallejo varnishs in the past as well with.

As the guys have already said, I tried adding Vallejo thinners (think it was about 50/50) and that improved things.

Also added a drop of flow improver to the mix.

I played around with sizes as well and found that using a bigger nozzle (4mm) helped – there was less clogging.

And only put a little bit of varnish at a time into the cup, washing out with water and/or a little bit of cleaner before filling again, otherwise it started clogging the tip after a few minutes.

It seems to be less of a problem in the winter for me, so I’m guessing the humidity at this time of year has an impact on the varnish as well.
