Liquid emulsion - which brush to use?

Hi,

I use Tetenal liquid emulsion with nice 250 gr paper. All is good, but I would like to get more visible brush marks on paper, final print looks "too normal", almost like normal print . I use normal brush for painting walls - 6 cm wide.

Also - I got 1 bottle of Tetenal liquid emulsion for 1 euro on flea market - expired 2002. I knew something was wrong because it was liquid on room temperate, but I give it a try. I get picture in developer, but emulsion just fall off from paper, and when I get to stop bath and fixer - it is 90% gone. Can I do something about it - maybe to mix with something or...?

thanks,

Perhaps ditch the expired stuff and then use any brush that gives you a good coating.

the expired stuff might give you nice contrast
( depending on how it was stored)
expired i use does
maybe a hake brush .. or a wallpaper paste brush ?
