Hi I wonder if someone can tell me what is the best way to seal the paper mache roman pillars the stand 4 feet high and of course are hollow but sealed at both ends some one suggested I give it 2 coats of polyurethene varnish and then paint them the colour I need them to be and then give it another coat of varnish it sounds like a good idea but when I went to the paint shop they were not really sure it would work. would anyone have any idea as I need to do this job urgently so I can hire them out for wedding functions
Thanks
SB
