Title: Brush marks/streaks using brush on varnish.
Post by: cram on March 23, 2015, 10:45:02 PM
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.

A sponge brush might work (basically, a sponge on the end of a brush handle), you should be able to pick one up in a decent art shop.

cheers

I wonder if that's a bad batch? I've never had that trouble with Daler-Rowney myself.

For me two or three coats always keeps the streaks away. A single coat often leaves streaks when using a brush.

Thanks everyone for you're help.

Using a sponge brush sounds interesting!

I found the following advice and gave it a go: http://blog.mitchalbala.com/picture-varnishing-get-the-streaks-out/  I'm happy to say it worked, no more streaks  :)

I know its not a direct link,to your brush marks question,But I was stuck reading an old scale modeler's hand book whilst waiting in an old bookshop.
In it ,it reccomended making a filter screen from tights through which you spray varnish to form a finer mist and avoid milking/clouding varnish over a finished model.I'd like to say I've tried this method but I haven't.Also forgive me if I'm preaching to the converted.But it wasn't a method I'd ever thought of or come accross before.
