Hi, I'm a painter and I'm thinking of using paper mache in a current work. I want to give some small parts of the surface quite high and quite distinct texture. The painting is in acrylics on canvas, and there is already quite a bit of acrylic paint on the surface. So I want to make a paper mache that will stick to an acrylic surface, take an acrylic paint and/or oil paint after it dries, be reasonably hardy, stay stuck on to a vertical surface and stand the test of time. Unfortunately, I'm a first-time paper mache user! I have read a lot of recipes on the web, and I'm confused about a couple of things. I'm hoping that someone might be able to clear up my confusion for me. Here's my bunch of questions... Why do all the recipes I have read use a mix of glues? (usually white glue (PVA) and a starch glue (wheat paste)). Do I need to use two glues? If I do, then what about methyl cellulose and PVA? [That could work - why don't you try it and get back to us? I've used straight PVA before, and it worked fine. The wheat paste adds a filler, and some body, but it makes it attractive to critters. Paper mache works best, though, if it's done the traditional way, with layers of paper and glue. As a thick clay-like mixture of paper pulp and glue(s) intended for adhesion to your canvases, it would work poorly, I'd think. Think of a big wet cookie slapped on there, slowly drying, crusting over, shrinking and growing mold...] Do I need to worry about adding a fungicide? (Some people seem to worry about this a lot...). If I do, would salt work? [That might help with the mold part.] Some people recommend adding small amounts of oil of cloves or linseed oil to their pulp. What is this for? (I have been reluctant to add any oil because I want to paint it, at least initially, with acrylics). [The clove probably makes it smell better, might repel some insects. I never heard of the linseed oil, but there are lots of linseed putties (which, of course, are more compatible with oil paints than acrylics.)] Some people add a small amount of bleach when preparing their pulp. Is this to make the paper white? or for some other reason?? [That helps keep the bacteria at bay, at least for a while...] I'd appreciate hearing any thoughts you have. I'd also really appreciate hearing whether you have tried doing somethinbg similar to what I have described. Thanks! Angela [I've done things with traditional paper mache, and have tried out "Cellu-clay" pulp, but found the latter of limited usefulness due to its inability to set up well in any thickness. I really don't think it's going to work too well in your application either. Look into modeling pastes, or mix your own from acrylic medium and marble dust (aka calcium carbonate). That's more likely to stick successfully to canvas, although this sort of thing always works better on a more solid substrate, like a wooden panel. If you want to work in textural paper mache, I'd say ditch the canvas and make your whole piece as a thin but continuous layer of paper mache, maybe laid on a screen, which can easily be painted with acrylics.] Andrew Werby Subject  paper mache glues  Re: paper mache glues  Re: paper mache glues  Re: paper mache glues
