Q&A (2)
Q HI, I was wondering if I could use this varnish on a watercolor painting on 300 gsm paper? I would very much prefer a spray varnish to one which needs to be applied by brush so this would be ideal. Thank you. Regards, Nadya

The spray varnish might cause a watercolour painting to bleed unfortunately.

Q Hi does this varnish contain UV protection and is it suitable for spraying on resin and acrylic items that have been painted with glass paints. ie I have made suncatchers and painted them with glass paints but it says they should be covered in UV varnish before hanging in sun. many thanks Pat

Sorry no, this is not a UV protecting varnish.

20th September 2016 Reviewed by Maree Coates First time I have used this product, so still getting used to it. It leaves a nice finish on the scratchboards, not too glossy.
