Surface preparation

[Guest]

Hello again. I have thre more questions if I may please and, as always, thanks to you experts who share your knowledge and expertise.

1. How long should I wait between applying the Vallejo primer and the Vallejo black gloss paint?

2. Having successfully applied my Vallejo gloss black coats (two of them?), how long should I wait before adding the Vallejo gloss varnish?

3. Is it best to paint brush or air brush the Vallejo gloss varnish?

Regards

A lot depends Aidan on the conditions that you leave the paint to cure.

Humid & cold is longer than warm & dry.

But in my garage which is well insulated & quite high on humidity (87% in Jersey 65% average London approx) I leave about 24 hours. Also use sometimes a gardeners incubator which gives perfect conditions & probably 12 hours. This is for matt Vallejo finishes. Gloss I have not used so I cannot answer for that finish. Varnish is the same for matt finishes although it is not the varnish it is the layer the varnish is to be applied to.

Have to say that I sometimes, after all the above, if in a hurry & want to get on I recoat, after the gardener's incubator session, within the hour or less. With matt it dries through both coats. If you watch Flory he dries with the airbrush on air only & gets away with it. Got to watch however the coat thickness or it will separate & you will get cracks with differential drying of the layers. Same I suspect with gloss as the undercoat & gloss may dry at different rates.

Can somebody help on gloss here ? Very interesting topic.

Thanks Laurie. I'm happy to wait 24 hours between coats. I'm the most impatient person I know, so this hobby forces me to be more patient.

With regard to the gloss black, I used it today for the first time. It twice clogged my airbrush until I thinned it, again and again with thinners, eventually to about 75%. All a learning curve!
