viscosity thickener

For IMpasto Effects 


This medium has been designed to be stirred into your paint colour to give a thick buttery consistency.

Originally it was formulated to give the perfect paint thickness for screen printing. However, it is now widely used to thicken colours to achieve an impasto effect in painting.

Add 2 teaspoons of thickener per 250ml of paint. Use sparingly as this a very effective medium (not compatible with fluorescent colours).

 

How to thicken your paint up to get a real textured impasto relief feel to the paint. 

You can use the sort of standard impasto mediums range. We make a couple of different products, a gel medium and an impasto medium. Very roughly, the difference is the gel medium will dry clear but not quite as much build as you will get with the impasto medium, which doesn't dry quite as clear. 

 


Why use Viscosity Thickener?

 

 When you thicken your paint with impasto or gel, you use equal parts impasto medium and the paint. With the viscosity thickener, you don't use anywhere near that; You just need to use a few drops to mix it in.  Now it does take a little bit of mixing, but this will chemically thicken the paint. Impasto and gel mediums are built to reduce the colour as little as possible, but, to get an actual texture, you've got to put quite a bit in, and anything that's not colour is going to reduce the colour.  

 

So by using the viscosity thickener, you get the same texture as the impasto medium. Still, you only need a couple of drops, and you get the impasto look but with no colour shift, which will thicken any water-based acrylic paint.

Once it dries and then the viscosity thickener dries quite matte, another thing to note with the viscosity thickener when you mix up the paint you want to use it all pretty well in one sitting. It might keep for a few days, but what will tend to happen if you add a little bit too much that is fine; however, it will tend to continue to swell if you're keeping it in a jar over a more extended period of time it will go quite thick and hard.  Paint that has been thickened with Viscosity Thickener should be used within 48 hours or so.

 

So if you've got any water-based acrylic paint that's a bit thin and you want to thicken it up, or you want to make it thick like an impasto modelling  Viscosity thickener is for you.
