Coatings for paper maché?
Q. We are making large paper maché angels for our church and have to redo them every year. They are out side part of the year. Some one told me to check into an acrylic overlay called Incralac ⇦this on eBay or Amazon [affil links] . I would like some information on this or any other suggestions you might have to preserve our angels. We don't want them to appear plastic and they have a lot of folds in the clothes and details on the wings so we will need something in spray form. Since we are donating as a group, money is an issue as well. Thank you for all your help with this.

A. Incralac ⇦this on eBay or Amazon [affil links] is made by many coatings manufacturers, under license from the International Copper Research Association (whose initials are obviously the source of the product name). They should be able to tell you of manufacturers in your area.

Q. Hi! I'm a paper maché artist, and have set myself the challenge of making useable coffee mugs made of maché-ed cardboard. I'm still looking for a coating to waterproof the inside, that would be food safe at drinking temperatures of between 155 °F and 175 °F (70 °C to 80 °C).
Grateful for any help!

A. Try beeswax; 'water glass' ⇦this on eBay or Amazon [affil links] may be an option. Japanese lacquer (urushi) can be used too. Hope it helps and good luck!
