Hello all,
I have come to this hallowed forum in search of advice. I have a little experience with paper mache and my current technique involves using bits of newspaper all lovingly squelched together in layers over a mould using wallpaper paste.
As you can probably guess this is a time consuming and labourious process, so in the interests of speeding up my production time I have decided to try out pulp version of papermache but (and this is where I need your lovely advice) I am somewhat wary about using just white PVA as an adhesive mainly because I'm worried that a) It's not strong enough and b) in hot weather the finished product might 'sweat' out the glue.
So am I being unnesscarily worried or can my problems be overcome?
Thanking you in advance.

I have used both PVA and wallpaper paste dry in my pulp.. and havent had any problems yet...
I usually use a filler in the pulp like cornflour as well to give it strength and havent had any probles with the glue sweating.. even in the heat of an australian summer

I am with EllenEggers. I use a mixture of wallpaper paste and white PVA in my dry paper pulp and haven't had any problems.
I have never tried cornflour though. To tell you the truth, I am not even exactly sure what that is. :oops:

Yup, 75% wallpaper paste and 25% PVA (white glue) is fine. You can also add some fine sawdust and ground chalk (or plaster etc). Aim to have NO water in the mix other than what is in the paste (double cream consistency). Dipping your smoothing tool or finger in water helps with smoothing. Depending on the fineness of your pulp, it should dry hard and sand (even carve) well. Contact me if you want anything more detailed.
