How long for Humbrol clear model varnish to cure and apply decals?

[Simon Robinson 4Participant @simonrobinson4]

I’ve painted my model with the 3 recommenced coats of Humbrol Clear, leaving over 30 minutes between each coat. It doesn’t say on the instructions but how long will it take for the varnish to cure so I can apply my waterslide decals?

Edit: it’s an acrylic varnish.

Is this acrylic or enamel?

From experience, the enamel is slow drying and wants a lot longer tha 30 minutes between coats, or it could take several days to cure.

Acrylic should dry a lot faster.

It’s an acrylic water based varnish.

This is what Humbrol say:

Enamels: Gloss: 1-2 hours. Matt & Satin: 20-40 mins touch dry, up to 24 hours for hard dry. Metallics: hard dry in approx. 10 days. Recoat: 6 hours minimum.

Acrylics: 1-2 hours ‘hard dry’, allow longer for Gloss and Metallic finishes.

Crossed in the post!

It should dry fairly fast, I would normally leave acrylic a day before applying decals, just to be on the safe side.
