Can you guys please help me avoid brush marks/streaks on flat surfaces using Daler Rowney soluble varnish? I've used a soft and flat headed brush to apply the varnish, when the matt varnish catches the light you can see the marks. I was wondering if diluting the varnish might help, but worried that this might effect how matt the finish will then be?
Any help would be great!
I know the obvious solution would be to use a spray varnish, but I have had disasters using this stuff in the past and do not want to use it again.
Thanks.
