Just with some boiling water removing the glass bowl
The cakes have hardened, stuck one cocktail stick end in one and 2 cocktails stick ends in the other to mark 10 and 20%, cut some canvas and nicked the missus' hairdryer;
First of all I applied the wax onto an unheated bit of canvas
Then gave it some heat
Totally soaks in, amazing to watch, was like it was evaporating (which it wasn't) Next I heated the surface of the canvas with the hairdryer before applying the wax
went on a lot better but still soaked in well when heat was applied
Repeated this 3 times and ended up saturating the canvas, which it what we are trying to do. Went right through onto the paper;
Left them to dry then ran them under the tap and watched the water just bead off them like quicksilver
As you can see, darkened the canvas a little bit and tbh there is not much difference in stiffness at all, I reckon any extra stiffness is down to how much is applied. I would do 2 or 3 heated coats at a maximum, any more than that and you'll be just packing it in. The 10 has two coats and the 20 has 3. As a result the 20 is a tiny bit stiffer.
So big batch next time I get the chance, reckon I'm going to go with the 20% mix, seems no real difference and if I wanted to I could always thin it with some turps but tbh with the hairdryer, not sure it's needed.
