A guide to airbrushing with house paint for terrain builders

hey guys now the terrain shooter back in the naughty corner with a bit of a back to basics guy for you and in this back to basics guy what we’re going to be doing is looking at house brought house bait through an airbrush okay now couple things probably get stuck in obviously this is a back to basics guide therefore it’s part of the back to basics series a series of guides designed to teach you not how to build specific terrain but to cover a variety of techniques and materials that are common to terrain building essentially to give you the skills that you need to build whatever you want okay so the links are there go check it out I’m sure there’ll be something of interesting there for you oh well now you notice this is a bit of a video on our machine yeah oh you also notice bit of an airbrush picture there that’s not mine that’s the Wyss casas yeah that’s her first attempt to airbrush it don’t you hate talented people you know I mean right I’ll get stuck into what I can do it okay spot some paint on right okay we’ve got house paint here now I’ve only been airbrushing for about two years so there’s two key facts I want you to take from that one I don’t consider myself any sort of a bush master or a bush teacher okay but in those two years yeah I have put a phenomenal amount of house paint through what should my airbrush is so I’m pretty confident of doing that and what I want to do it’s just basically take you through everything I’ve learned along this year two year process to sort of say if you haven’t the same problems that I’ve gone through when you give it a go if you decide to give it a go now secondly the other thing I want to take you take that from that is I’ve been doing it for about two years building terrain for over 20 okay so an airbrush is in no way essential to terrain building don’t think you’ve got to go out buy yourself a compressor and a professional airbrush you don’t yeah all the stuff you seen on my channel so far brush works sponge work okay guys so don’t think that you need an airbrush that being said yeah like a lot of artistic tools and mediums they can only improve your work well which got a handle on you know army okay so we’ve got that we cover that yeah I think the best thing we can do is let’s talk about some paint a and where does applicable come cry over to the desk okay guys as you already know we sort of use all sorts of painting in terrain building yeah we use model page we use craft and our tillich artistic acrylics yeah we use emulsions yeah house painter latex paint if you in the US guys yeah and they’re all good and they all have the purpose now the reason why we sort of move into the emulsions as terrain builders is simply volume of paint when you’re building tell me when you come in a 6×4 when you do lots of buildings you’re using a lot of pain and it just does makes these sort of things on viable so we tend to go for the tester parts we tend to go for the small litre tins and if you’re proper you know full-on Tory maker you buy 5 liter tins okay but I want to quickly talk to you about these sort of paints with regards to airbrushing now model paints and professional paints like these these are badges Minatare and sterilized primers really really good yeah designed to go through badger air brushes and air brushes yeah to work straight out of the bowl yeah they’re brilliant but volume-wise they’re not suitable for anything other than detailing work okay so we can’t really use those for bulk terrain yeah which moves us into the art the acrylic Department okay and in the acrylic Department they call in to two fundamental camps yeah you’ve got Kraft acrylics okay and artists acrylics okay the difference being is Kraft acrylics they’re made for kids and people messing around with it yeah consistencies can vary I mean look at this two bottles two tubes of acrylic green SAP green they’re not even the same color or anywhere close okay you you can get them to run through air brushes but you consistency and making sure it works right every time can be a bit challenging so when it comes to airbrushing you really want to start favour the artistic acrylics the reason for that is they’re designed to to a specific recipe to a certain consistency yet because they use by professional artists and on top of that yeah the companies who make them like Windsor neuter and all the other companies yeah they’ll have professional thinners forum and how to thin them down to put through air brushes okay so they decide to be worked with you know thinners and things like that so stepping up if you’re doing you know reason about my work you know we like these but like say for a book work and what we’re talking about now is mainly you know your base coating stuff okay getting your color down quick you know

you your subtle shadings those sort of things okay we move into the house paints now you already know that we love house paint I love how to paint yeah the Train building well there’s a bit of a problem with house paint yeah do you read the development of house paints okay I am pretty damn sure that no sort of paint chemical engineer sat around the table I went what if someone was putting through an airbrush that conversation never happened I put money on it that conversation never had happened and so putting them through an airbrush is ex has challenges okay they’re very thick of a they go together I’ll talk about the challenges in a minute to be true for you as we go through but the purpose of this video it’s going to be showing you how I cope with the challenges they present okay so I think the next best thing we can do yeah it’s really just get stuck in guys yeah so what I do is we’ll get some paint we’ll get the airbrush together and we’ll do some spray and I can talk to you about the challenges that this paint faces and then we’ll go into sorting them out and mix it up and all that sort of stuff as crack on now before I start showing you how to mix it up and how to troubleshoot problems and that sort of stuff as you go in and best tips well I thought I’d do is I’ll quickly show you the difference between the consistency we have to use a motion painter okay and normal airbrush consistency yeah so what I got in here is I’ve got my Flintstone yeah it’s already been sort of pre-mixed and down it’s in a little plastic dropper bottle you get them from eBay it’s got a marbling as an agitator yeah and yeah we’re just going to put a couple of drops into here yeah if you see yeah that’s the salt consistency let me put a drop there yeah you can sort of see yeah okay now if I put that out and I’m pushing out about 335 psi working pressure and all I’m going to do is push it out there yeah you can see works fine so now the thing I want you to take from this is notice how it looks a bit wetter than normal airbrush it yeah so if I get my finger now yeah you see how it’s wetter than normal airbrush it okay if I come back up here really blast it out give our second what you’ll notice if you can yeah it’s that the moisture is being drawn away and there’s quite a bit of moisture in here to be perfectly honest okay and the reason for that is that the paint is so thick that you have to go over the top yeah with moisture to get it through the problem is if you go too much over the top with moisture yeah so I’ll quickly flush that out yeah now the solvent for this is just water okay so I’m just going to flush it through with a bit of water and I’ll be fine yeah I’m just floating it into a jug yeah there you go right if I just put that down for a second if we go mix okay putting our paint now you can see also a thick it is matte yeah so slowly it runs okay we had a little bit of water we mix it up to what we call yeah or what they say for our brushes is the consistency of milk yeah I mean that’s a little bit thicker than the consistency milk another drop okay so there you go oh so the camera Bose oh yeah okay let’s Shuman that’s focusing right if we put this in our airbrush here which is airbrush consistency okay what they recommend will start spraying this look at the moisture in it yeah to see that to see how much moisture is there let me move that tin there you go the fragile tape doesn’t help does it but you can sort of see how

much moisture is in this so if I come across to something like a rock okay I’ve gotta go really slowly because very quickly yeah it becomes like a wash see that see how he’s running away yeah it’s simply too thin now that means that if you fill it down to what they recommend for putting through air brushes yeah you’re going to have to do typically about three or four coats just to get a base coat on yeah and trust me it’s frustrating but it will go through and it will continue to go through it’s easy to clean yeah if you want to go thicker and work a deeper shade you know you know a more opaqueness to airbrushing then you need to put it in at the thicker ratio okay so that presents a future problems okay because obviously it’s thicker yeah it really does gunk up inside so what I’m gonna do now is we’re going to what’s best should I show you the trips and the gunking or let’s mix them up ah let’s show you the gunk in right what I’m going to do is bang out a load and bump this off a bit yeah now when you’re airbrushing and we just blow that out yeah when you’re airbrushing there’s a tendency to fill the cup right up and just crack on the problem is because we’re airbrushing yeah what happens is that paints it in there for ages and ages and ages yeah while you’re doing airbrushing and it all starts to thicken up at the bottom you start pulling the thick stuff through the bottom yeah through the airbrushing and it gums up okay so my recommendation is if you are using emulsions and you’re running them thick yeah run them in a little bit okay so a couple of drops in get the bit you need to do yeah run it through yeah every so often I’m doing it now I don’t need to do it now but every so often yeah run a bit of cold cold walk through it the solvent is cold war after all so it’ll be fine yeah yeah that just pushes it through and then whack in a little bit more paint and crack on I may see it may seem a bit sort of long-winded to keep having to top off okay but the benefit is and you can go if you’re really working out you can go to sort of half a cup don’t go about half a cup yeah but the benefit is but as you’re whacking it out and as you’re little topping it off you’re not clogging it up which means you’re getting a fire fine spray yeah you can push it out if you need to let me just pump this law out and then I’ll show you the gunky good okay guys right you see straightaway where we’ve done it with the thicker emulsion yeah we’ve got a far nicer coat on that than sort of it the consistency they recommended watch call it consistency of milk right so I’ve blown a little bit through yeah I could normally put a lot more through than that but I just want to show you something yeah now I’m gonna have to bring this up I’m gonna have to dismantle my airbrushed in front of the camera okay now take off the front nose assembly and then inside may you will

have a cone and a needle okay so there’s cone yeah there’s your needle you know air comes out of here goes round that cone sucks the paint out and how much paint comes out depends on how far back that needle is pulled now if I take this cone off look at that yeah that’s how gunk that needles got already yeah that is very different to airbrush watch click to airbrush paint okay if that was an airbrush paint I’d expect that to be you’d see metallic even with that little amount okay so you can imagine how as you’re going along and you’re whacking it out and your base coat in buildings that very quickly Gunks up yeah so tips for managing that first off top up frequently but don’t fill up okay do flushes ie yeah get your water couple of drops in when you get to the bottom just flush it through yeah finally there’s a little tip and I haven’t got any wet rag full full full dose right let me just put a bit water on that you’ll see why in a second now prior to this I was sort of doing it [ __ ] handed yeah well I sort of drawing the needle back and put my finger on all sorts thing but there’s a technique when you’re cleaning your airbrush called back flushing okay I’m back flushing involves blocking the air flow at one side in the needle back and pushing air through because they can’t come out of here it goes around that code and back in and it forces everything that’s thick back out yeah into the cup and it’s a good way of clearing blockages but you can do what I call a field flush yeah now typically you do back flushes when you’re washing yeah can a badger getting with this tip for these because they’re they don’t have pinch tips they don’t it’s quite challenging to gripping yeah a little bit water say one or two drops yeah okay and you click only a couple of drops on this because if it’s otherwise trust me you’ll cover yourself in pain yeah pinch the front with a damp cloth with these or you’ll use a pinch tip yeah let the air go and blob licking sounds lovely that’s why you don’t put loads of water in you’ll cover yourself yeah what are you doing that is you’re forcing all that paint out yeah do that yeah throw the excess into a jug flush yeah and if I open this needle again come on baby that’s it hmm knocking me joke over yeah I’ll tear that out yeah a marked difference on that and absolute mark difference is nowhere near as thick okay it is ready to put pain through yeah that isn’t gunked-up at all yeah so that’s called a I’m calling that a field flush yeah I don’t know if I hairbrushes do it I am seeing it it’s just what I sort of do to sort of speed it up when I’m doing lots and it’s stuff and I notice the airbrush is starting to hesitate yeah that’s when it literally is I’ll force out what paint I’ve got out of it yeah dump it yeah push it out clear it out give it a flush through and I can crack on and it’s a lot quicker than having to take it and clean it properly you know take it over to the sink clean the needle etc because you’re using the same colour okay so that’s the basic principles of pushing I want saying now those get your words in order I’m all over the place today so I’m a little bit excited I’ve been to see an artistic space too today and I’m really excited about it I’m sort of bouncing you know so sorry if I’ve been a bit ahead you know as Ian all over the place for those things in it so take a deep breath and get yourself together both so guys really simply yeah you can now see why it needs to be thicker than normal watch like the normal airbrushing pain yeah because you can’t get that opaqueness yeah without a thick nail up but because it’s thicker it’s more prone to blocking yeah and the paint is designed to glue together yeah it will literally I mean it’s thickening in this so quickly and that was the really watered down mix okay it’s designed to do that it’s designed to protect your walls okay so we’ve got a cope with that and coping with that that simply means making sure

you know when we when we top up shake a bottle so it’s the right consistency we do watch go it flushes you know every so often we do field flushes and back flush it every so often we only top up little amounts we don’t use a full cup sitting okay simple as that yeah now next up we’re going to talk about mixing paint and what we’re going to do is I’ve got a couple of black tester pots here I don’t have a black paint mixed up so we’re going to do it first time and I’ll take you through the process because the issue is none of these paints have been designed for airbrushing so every single one can be different when it comes to airbrushing yes so I’m going to take you through basalt and markers I use to figure out is it thick enough is it thin enough yet will this work okay guys so I’ll get cleaned up and we’ll get back with a bit of mixing see a sec okay guys hopefully after that sort of rambling bit sorry about that guys you should have a better sort of handle on why you need emulsion to be thicker than normal sort of airbrush paint okay and you should have a sort of a handle on the inherent problems of the thickness that causes when airbrushing and a few little tips to sort of like handle it as you go you know the back flushing the flushing through you know top it up only what you need etc yeah just a quick word on that you can actually fill the cup to the top in one go but I’d only recommend it if you’re doing one sitting if you intend to keep topping it up and that sort of stuff don’t keep with the low measures okay guys right now you’ve got a handle on it I’ll take you very quickly through the mixing process and the testing process as I said emotions aren’t designed yet to go through air brushes so consistency is very considerably yet from pot to pot brand to brand yeah so I’ll show you I’ll give you a couple of pointers yeah on mixing it up and knowing when you’ve got the right sort of mix right we’re going to do black because I’m going black yep so let’s crack on yeah first job yeah we’re going to empty I mean you’re not going to put that through an airbrush anytime so you know you well will in a couple of minutes let’s drop that in nasty pop this one now this one’s a little bit better see it drips a bit let’s get that in there come on now you may say should you scrape those out get more out now I’ll throw some water into and make them into a black wash get that get the sword remnants that way it’s easier and quicker for you guys right so put those over there out of the way so we have our black paint okay I’m that much of a cop yeah next thing I’m going to do is I’m going to pour probably about two three mil flow rate in there okay ah this is a Windsor Newton’s artistic acrylic flow improver remember emulsion paints are acrylics yeah so it works fine with them yeah I’ve dieted mine down to a 1 to 20 ratio but like this will last you forever yeah but that simple couple of MIL there you go yeah now I found flow aid is pretty essential yeah now you may not want to pull out for the expense of it but my recommendation is pour out for the expense for it yeah it makes a vast difference I mean look how gloopy that is the next job yeah it’s to start topping it up with water okay and what I do is I put in a layer we spread everywhere like a certainly night yeah just a layer yeah and then start mixing that backwards and forwards I do not fill it with like a centimeter and try and mix that and it’s too much in one go yeah so what I’m going to do now is I’m very going to quickly mix this up and see if I can get this to airbrush consistency from that okay so cue the music and here we are the guys that is roughly the right consistency now yeah just thick enough okay the trick to tell is when you pour it in if the ripples disappear almost immediately yeah that’s the moment I find that it’s best to go through now remember we’ve got a troubleshoot this

so next job let’s put some through an airbrush yeah so very carefully now I’ll just put a couple of drops in without making a horrendous mess yeah there you go then we’ll come over to our lab board without tape now see how improves the quality again yeah and perfect all right as you can see it’s going through nice yeah I’m not getting any excess moisture okay yeah not like when we did flush with that one so let’s see how long it flows for you yeah if you look at the bottom yeah you see a little bit of metal so it’s not glue pin yeah so I would say we’ve got pretty much perfect consistency there now okay let’s see what happens if we add a little bit more water yeah so what I’m going to do is yeah bit by paint yeah not the flow brother dude yeah a little bit of water yeah just a couple of drops hmm give it a mix okay and this is back down to that sort of consistency of milk thing again yeah if we put through the consistency of milk yeah access again to get a decent coverage yeah you see hmm whereas let me just throw that feel flush if we put it in our proper consistency a couple of drops yeah throw that round obviously blow out the excess water from the start and then yeah that’s it the consistency of milk that’s our thicker ratio yeah so there you have it guys it’s as easy as that to mix oh yeah remember your pointers remember to watch your look for excess moisture when you’re doing it over cardboard when you spray over cardboard the moisture will get sucked away yeah into the sides okay so you’ll be able to tell if you’ve got excess moisture alternatively any sort of rocky Rock something which would run bits over yeah run it over that yet have a look yeah if it is running its to run it’s too thin you need to thicken it up yeah that should let’s wrap this okay cuz I think yeah you’re good on mixing now obviously all I’ve got a lot to do with that is pour it into that put an agitator in it and we are good to go really good to go I like this black it’s really nice and shiny right let’s wrap this up and relax sorry I’ve been hyped up on this one guys like say loads of good things going on the army so I’m in a bouncing mood yeah so gives you an edge if you know what I mean right there you go that’s a round upon using emulsion paint yeah this especially applies to sort of terrain builders you know the colors you’re putting out for use if you get it together with you know your cloth and you want to do a load of trade and wonder if you’ve got an airbrush yeah then this is the sort of information for you what I’d really like you to take from this is above all understanding that these paints are not designed to go through an airbrush okay so you’ve got except that they’re different consistencies they have different properties yeah they clump faster than a bush paints and you’ve got to be able to handle that one mixing it up and understanding you know what’s too much what’s too little remember you know if you’ve wondered about consistencies put a bit in mix a little bit of water in there take it thin it in the brush and see before you ruin your entire pot okay

and have to leave it out if you do go too thick okay weird watch for it with sorry if you do go too thin when you’re mixing it yeah leave the pot out but the paint will very quickly sit to the bottom and they will become a thin layer of water at the top take your cup pour it pull the thin layer off very quickly pull it back up yet and then you back to a thick dense density in about takes about five minutes for the process okay so company picking it back down by pulling off the after it’s settled okay we’ve also covered a couple little cheeky tips one the idea that you know acrylic paint is designed to wash with water to dissolve with water okay it’s designed to yeah yeah absol sinks etc so water is you is your watch and solvent feel free to you know if it’s often but cook the drops in just flush it through it all helps remember cheeky little pinch the tip and back flush but don’t overfill it otherwise you’re gonna copy self and paint like I’ve done a few times okay I did it did it when it we talked about the top it up bit yeah frequently not too much I think that about covers it right guys like say so it’s been a bit all over the place but hopefully yeah you’ve got two years worth of plenty of cock-ups to be perfectly honest and screaming and shouting clean my air I mean before I figured out the flow rate I was cleaning that every five minutes keep away from the Chinese brushes whatever else you go for guys keep away from the Chinese ones yeah they’re not worth it no matter what you think at the time Yeah right guys that wraps it up so as always liked it if you liked it if you’ve got a comment if you’ve got any experience if you know anything like that any questions in the comments I always answer my comments and it’s a resource guys to remember check out the comments finally you know listen guys if you really like what I do yeah and you want to help me with this and this passion of doing this terrain tutorial stuff full-time yeah consider patreon guys I know I only ask a dollar a month yeah but they really do all I’d up and it gives me this freedom it gives me this kick it gives me the ability to share this why I’ve learned what I know with you guys okay so it’s there if you’re up for it if not don’t matter yeah we’ll crack on regardless but appreciate it if you consider it right guys that wraps it up in the meantime I will say more interesting stuff coming in next week’s tutorial it may move to a Thursday depending on how quickly in timings and things like that but in the meantime I’ll see you Sunday night nine o’clock words for us see you then guys live show Sunday Tara
