Acrylic Home Brew Thinners : Tutorial
 


Genessis-Models - A Novice Modellers' Saviour

I needed a hobby, something I could apply myself to when the weather made golf and gardening an unpleasant past time. Last week I accompanied my wife to the mall, which is a rare occurrence because shopping is something I compare to a root canal when it comes to desirable ways to spend my time. As we strolled about, we passed a hobby shop. I excused myself from the hunt for the perfect pair of women's shoes, promising I'd be in the shop when the time came to head home.

Much of the shelf space was dedicated to model cars, planes, trains, battlefield recreations, tanks and ships. I'm a history buff, and I like to think I have an eye for detail, so modelling appealed to me. I selected a World War Two Messerschmitt Bf-109E in 1/48 scale. When it came to selecting paints and thinners I must have exhausted my allotted time with the clerk because he recommended I visit a website called Genessis-Models, at genessis-models.co.uk to learn about building model.

At home I visited the Genessis-Models website, which offers a forum, store, news, and a photo gallery, but my attention was caught by the link to videos. One video in particular that caught my eye was titled, "Home Brew Thinners". Having just purchased the tiniest bottle of thinners I'd ever seen for double what I was used to paying for a gallon of paint thinners I thought I'd have a look.

AI'd just spent the better part of eight pounds for a couple of hundred millilitres of acrylic thinners, so I was thinking model building was going to be a costly hobby. To learn from watching Bobby Waldron's informative video that I could economically create gallons of my own, home brew thinners was a welcome revelation. I immediately subscribed to both the website and to Bobby's YouTube channel at http://www.youtube.com/user/genessismodels.

For other novices reading this, Genessis-Models is for anyone interested in modelling, from a total novice like myself, to advanced modellers. The Genessis Models website is a great place to pick up tips, tricks and a wide range of techniques to build first class models. The on-site forum is the ideal place to have any questions answered, to find solutions to problems, or get advice on how to avoid problems in the first place.

I regret not finding Bobby Waldron's Genessis Models website and videos before I started my modelling hobby on a whim, but now that I have I'm a faithful follower. Thanks to Genessis-Models I've managed to save money and turn out some models I doubt I could have without having Bobby's advice and tutorial videos to go by.

Thought I'd try this brew when first posted. However, without an art store nearby and not wanting to spend a small fortune on having retarder and enhancer posted, I made a slight adjustment following some research. Among others ...... http://en.wikipedia.org/wiki/Acrylic_retarder
Go to the baking section (flavourings) of your supermarket and find Glycerine or Glycerol (Asda 59p !!!!) Use that in place of both the retarder and enhancer. I have used on Tamiya and Mr Hobby and the paint lays down a treat. Am about to paint the interior of a Spit using xtracrylix so will report back on that outcome.

Wow, way to go 'helldriver'!

While waiting for your report back... how much Glycerine/Glycerol did you use; same ratios Bobby used?

Good find there helldiver

wikipedia says this

Home-Made[edit source | editbeta]

For home-made acrylic retarder, water glycerol down about 5:1 (water: glycerol) and apply to paint.[1] Non-toxic car anti-freeze, which contains propylene glycol can also be used.

Sounds to me like a good basic mix for retarder,

I have also found that cheap washing up liquid makes for a good flow improver.

so there you go looks like you just got cheaper ;-)

I use 150mm HDPE plastic bottles, so easy to eyeball the 2:1 ratio. To this add about 2mm of the Glycerine and shake to the appropriate music. Also, I used distilled water, again from the s/market. Aidan

Good stuff Bobby. I think I'll try that. I think the cleanest water would be distilled water, it couldn't hurt, right?

Bobby + 'helldriver = 'new product' 

I found this great(?) source; aside from plastic bottles, they even have IPA 1 litre for £3.99 + p&p =£3.29.

http://www.ebay.co.uk/itm/1-X-1-Litre-IPA-ISOPROPYL-ALCOHOL-ISOPROPANOL-LIQUID-99-9-Watertight-Screw-Cap-/281118434574?pt=UK_BOI_Medical_Lab_Equipment_Lab_Supplies_ET&hash=item4173f6e50e  

I live in Norway and here they colour IPA blue and call it, yeah...'Blue Clean' ... the mentioned ebay seller doesn't ship to Norway.

Hi Bob! Have you used tamiya lacquer thinner (or Mr Hobby leveling thinner) to thin acrylic paints?

I read that many swear by lacquer thinner, in particular Mr Hobby leveling thinner. However, to me it puts back all the nasties that we were trying to avoid by using acrylics in the first place! I was surprised at how well the home brew works, even with xtracrylix which can be a right royal pain sometimes. Aidan

Hi Diegodc84

I have not used the Tamiya lacquer thinners but have used the Mr Hobby Leveling thinners, what I can say is it does a great job for the mr hobby rang of acrylic paints but does make them take longer to dry, this is because there is a high level of retarder in there which is why its says leveling thinners on the bottle because that is what retarder does, levels your paint to a nice smooth finish at the cost of longer drying times.

It really does clean your airbrush really well also, but its not so good on the lungs.

Bob

morning bob...just been  using the forum for a few months now and will begin my subscription to the whole site  1st January... I came across this video for the homebrew thinners which I'm about to try, once my IsoP arrives, I have the other stuff but I prefer to use the self levelling thinners by Mr Color... can you tell me how much of difference a difference I will find ????

Also, I too have used Xtracrylics paints for the first time on My Revell Hawk and had a nightmare with the laying down. I was using Mr Hobby color self leveling thinners. From your comments this seems to be more of a MR Hobby recipe, which I prefer, than Tamiya acrylic's thinner one ..would I be right in thinking that?

I would say that the home brew thinner's is more like Tamiya's acrylic thinner's, with the added bonus of working really well with Xtracrylics and all know acrylic paints.

Mr.Color Leveling thinners is a lacquer based acrylic thinners which is why its so good at cleaning an airbrush, you can even thin enamel paints with this stuff too, but your then going into the toxic enamel side of things that is bad for your health.

Hi Malcolm, hope you don't mind me adding my 2p. I use my version of the Homebrew and use it for Tamiya, Gunze AND Xtracrylix which are notoriously temperamental and would use it even if I was given the others foc! If trying it, don't be too generous with the enhancer and inhibitor (I replaced these with just about <5% of glycerine!)
Also, DO NOT use the Mr Hobby Color SLT on xtracrylix or you are likely to have a gummy mess.[biggrin] Aidan
