DoubleT Posted February 11, 2017 Report Share Posted February 11, 2017 For starters I would like to say I am new to airbrushing but have enjoyed what little time I have tried my hand at it. I am airbrushing plastic musky baits that I hand pour. A problem that I experienced yesterday occurred when I went to spray the solvent based clear over the water based bottom coat. It looked like dust coming out of the nozzle. After doing some research, It appears that I need to add some retarder to the clear. Does the retarder also act as a thinner or does it only prolong the drying time? That brings up another question. Will a thinner only thin the clear and leave me with the problem of it drying to fast? Again, I am brand new to airbrushing and I appreciate all the help I can get. Thanks Quote Link to comment Share on other sites More sharing options...
Basseducer Posted February 11, 2017 Report Share Posted February 11, 2017 I have found that the retarder does thin the paint/clear as well as slow down the drying.. Thinner only thins and may speed up the drying. I was told that hot climates require the use of retarder. Quote Link to comment Share on other sites More sharing options...

McLuvin175 Posted February 13, 2017 Report Share Posted February 13, 2017 What kind of paint are you using? Quote Link to comment Share on other sites More sharing options...

McLuvin175 Posted February 15, 2017 Report Share Posted February 15, 2017 Have you used any kind of your own thinner with the SB Coat Clear? I would contact Bruce at LureWorks and let him know about your issue. The SB Coat should be ready to spray out of the can, unless it has set on your shelf for a while or you left the lid off for a time it should spray. The issue of dust as you call it, or cob-webbing as I refer to it means that the paint is drying to quickly, even before it hits the bait. This is to be expected with the solvent based VPI series but the SB Coat is pre-thinned. SB Coat Retarder or SB Coat Thinner will help this issue. As a possible work around you might want to open up you airbrush to move the maximum amount of paint and reduce your air pressure as low as possible. The solvent based paints work better when you push a heavy coat, not so well with feathering. Let us know what you come up with. Quote Link to comment Share on other sites More sharing options...
DoubleT Posted February 15, 2017 Author Report Share Posted February 15, 2017 What is a good starting point for the amount of air pressure that I should be spraying the SB coat at? Would it be the same for the CoLure (water based) coat as well? Thanks for the help. Quote Link to comment Share on other sites More sharing options...
McLuvin175 Posted February 16, 2017 Report Share Posted February 16, 2017 Pressure will depend on your air brush set up (gravity vs siphon) and size tip or orafice, and if it is double action vs single. etc. I have used a Paasche siphon feed and 20-30 psi is sufficient for both solvent based and waterbased. That number should translate to most other airbrushes. Quote Link to comment Share on other sites More sharing options...
DoubleT Posted February 16, 2017 Author Report Share Posted February 16, 2017 Ok. Thanks. I have a Paasche double action gravity feed with a .38 mm (.015) tip. I was spraying the clear at 30 psi when I was getting the cob webbing. I got my retarder yesterday. I'm going to give Bruce a call today and run it by him. Hopefully I will get it resolved soon.

Frank Posted February 17, 2017 Report Share Posted February 17, 2017 Add just a bit of retarder and it will be fine. You are on the right track. Quote Link to comment Share on other sites More sharing options...

Landry Posted February 20, 2017 Report Share Posted February 20, 2017 I Ann gonna start to use the sb paint soon. Ordered a ton in the Fall. Sorry for the hijack but: What do I use to clean my airbrush after??? Quote Link to comment Share on other sites More sharing options...
DaveMc1 Posted February 20, 2017 Report Share Posted February 20, 2017 The thinner that Spike It sells for the paint. 1 Quote Link to comment Share on other sites More sharing options...
Frank Posted February 20, 2017 Report Share Posted February 20, 2017 You can use lacquer thinner to clean everything. It is probably easy to get in your area and cheaper. Quote Link to comment Share on other sites More sharing options...

McLuvin175 Posted February 20, 2017 Report Share Posted February 20, 2017 Lacquer Thinner may or may not work for clean up. It will depend on what the Lacquer Thinner is composed of as the blends can vary by manufacturer. You'll have to test what you have to see if it will work. Mild solvents will work when the paint is wet for clean up like Acetone. Once it has dried it is a different story you might need to step up to something more aggressive like Methyl Ethyl Ketone (MEK). It is best usually to use what the supplier recommends but those are some alternatives for clean up. Quote Link to comment Share on other sites More sharing options...

Use acetone 1st then the Spike-it thinner last. Air brushes still need to be disassembled periodically and thoroughly cleaned Quote Link to comment Share on other sites More sharing options...

Trout, Are you cleaning or thinning with the alcohol? On 2/16/2017 at 10:21 PM, Frank said: Add just a bit of retarder and it will be fine. You are on the right track. I put a few drops of retarder to about a half dozen drops of clear and it was still cobwebbing. Maybe I didnt add enough retarder? Wasn't sure how much would be too much.

I know when you start you don't want to use large amounts but when using small amounts it is hard not to over do it. Retarder slows the drying down. Over doing it will not hurt anything at all.

I will keep adding it in small amounts till it quits cobwebbing. Should I be able to shoot it at the same pressure(30 psi) as the paint? I got a little frustrated and gave up on the clear. The other colors seem to spray fine straight out of the bottle. Thanks Quote Link to comment Share on other sites More sharing options...
