airbrush for varnishing??
« on: March 19, 2007, 08:54:28 PM »

Hi,

Has anybody used an airbrush to apply satin varnish? And if so, what proportion did you thin it, and what did you use as thinner?

I have just experimented with 50/50 satin varnish and white spirit, seems ok, but would appreciate advice before i commit to my drifter hull.

Thanks in advance

Not tried that, but I've just ordered some ready mixed Revell airbrush varnish. Will let you know how good it is. I find the air brush enamels from them to be very good.

I use a Badger 250-4 airbrush and a Machine Mart compressor for the job and, until I discovered Humbrol Satin Cote, I also used Ronseal Clear Satin (Interior) and white spririt. 50/50 seems a bit thin, but if it works for you then do it!

Hi,

Since asking the question my local B&Q has expanded their stock of Plastkote. They now have satin polyurethane varnish in spray cans.

I got one and have just tried it on the rudder, it looks just the job!

Hi Ian

Be interested to know how you get on with the plastikote varnish. I tried some last year and found that the air ran out very quickly leaving a considerable amount of varnish in the can. I bought 2 aerosols from different vendors to try and be sure it wasn't a batch fault.

Cheers

I used it once and found that it went yellow very quickly; that the floor of the garage where I did the spraying was sticky from the overspray for ages afterwards; that the hole in the nozzle was too big for a fine spray (i.e. I couldn't get a thin coat onto the model), and that the pressure inside even a new can wasn't up to much. It's also b100dy expensive.

Apart from that it's wonderful stuff.....................

Suit yourselves, eh?

Luckilly it is the only thing I can get cheapish here.
It is about equivalent of 3.20 ponds for a 300ml can


I just wish there was the equvalent of Halfords.
I can't even get red oxide or poly'u'

Tamiya stuff is about 3 quid for 100mm.

There is some other stuff that is dearer.

hmphh, well, in that case I shall stand the tin in boiling water for 10 mins before I use it - that will help.

NOT BOILING!!! Hand-hot will do, or you might have the thing explode. "Sticky mess" wouldn't even begin to describe that!

 Does anyone know 'what exactly' does the Plastikote paint contain.

My reason for asking is that I notice that it's expensive stuff.  I haven't tried it because their cans seem smaller that the average, and the pots of brush paint are also very small for the price. 

I am assuming it's a one coat covers all, type of paint and might be a shinny gloss !!.  I maybe wrong. Perhaps someone could advise please.

The Plastikote I buy is in 400ml aerosols. Not tht small.
Cant remember how much the gloss costs but the primer is about 7.00
Having said that the coverage is very good ,a lot better than Humbrol or Tamiya plus you can spray it on most things.

Hi Ken

Most of the plasticote paints i have used seem to dry to shiny finish  also check out you floor the following morning  where you have been spraying. If you do not were a mask you will be shocked when see what is on the floor  I find that  humbrol paints will take some beating and there range of clear varnishes are very Good. if you use polyurethane  varnish that is not clear you nice white paint job will soon be a off white colour. New humbrol paints seem to be lot thinner and req less thinners found out the hard way 50/50mix seems to end up like water.

hmmm, the plastikote varnish I tried has dried a bit shiny, not so brilliant, think I will try the 50/50 thinned version as I said before.

Probably teaching you to suck eggs, but I find warming cans in a bowl of warm water for a couple of minutes improves pressure & thins the paint.
