Although I have used, and recommended Hairspray in the past, do be aware that it is not Archival, and your papers will discolour after a while. I have just been recommending this company, Crafters Companion,
elsewhere on here. They are in the UK, but they now have a USA site too. They do a product called Spray & Seal Satin Varnish
, which may be what you need. This is what their site says about it:
Spray & Seal is a varnish specially developed for interior and exterior use or for use in decoupage and scrapbooking which requires protection from humidity, dust and both hot and cold liquid spills. This spray varnish contains UV and humidity protectors and is effective on most materials and offers protection against UV, wind and rain for up to two years.
- When used in scrapbooking and decoupage it enables a decorative product to be protected against even hot liquids. Most other products protect only against cold liquids.
- Unlike many other varnishes of this type, Spray & Seal does not even wet tissue or fine paper.
- Does not cause yellowing as with some other competitor products.
- Due to very good coverage, Spray & Seal is very economic in use. Some competitor products require several coats to provide an acceptable finish or satisfactory level of protection.
- Can be used on most materials including ceramics, glass, wood, steel, tissue and fine papers. Many other such products work only on paper or card.
- Can be used on polystyrene. Most other products of this type can cause damage to polystyrene.
- Does not contain water or acids and is lignin free.
- Protects against U.V., wind, rain, dust and humidity
- Satin finish won’t alter your work, but multiple coats may be applied for a gloss effect.
if you go to the 'Crafting Sprays' section, you will also see they have glittery spray varnishes too. Hth
