Is there a downside to using Lahmian Medium?


Recommended Posts

I have been painting more white recently and found that thinning with water was just not producing the results I was happy with. I tried Lahmian Medium and have been able to thin paint to a lot finer consistency that has let me create a lot smoother results.

 

Is there a downside to doing this apart from having to buy the medium?

The only issue I've had with medium, is applying it over a transfer & it end up going misty on that area of the model.  But for thin paints or making glaze, I will always use medium over water.

Are you putting 'Ardcoat on the transfer before the Lahmian medium?

 

Because I don't have that issue, and I do 'Ardcoat > Transfer > 'Ardcoat > Lahmian Medium

 

From what GW have said elsewhere, it wouldn't surprise me if Lahmian Medium were a form of dilute matte varnish (Darren Latham uses it to get a consistent matte finish when weathering metallics, for example). I'm not sure if it's compatible with GW's formulation (I don't see any reason why it wouldn't be, but haven't tried it), but Vallejo make a thinning medium (73.524), which comes in a 60ml pot for around the cost of a pot of Lahmian medium - as it's just acrylic binder, it does a good job of thinning the paint without reducing adhesion.

 

 

If you're looking for an alternative, another option would be a flow improver (e.g. Liquitex Flo-Aid, Winsor & Newton Flow Improver, etc) - I use these with Formula P3 and get very flat coats, even on things like yellow where you need 42 (:tongue.:) coats.  Using too much can create issues with adhesion/resilience, but realistically you don't need much.  Alternatively, you could use white acrylic ink (e.g. Liquitex, Daler-Rowney FW, etc) to thin it. :)
