Hi All!! I desperately need your help and advice! Here is my situation. I have a 200 sq. ft. vault area, concrete construction on an out side wall. Controlling the humidity in this area has become the bane of my existence! I run a dehumidifier constantly and check it twice a day. I have adjusted the temperature, contacted the AC/Environmental department to check it....Seems no matter what I do there are still humidity spikes (sometimes a much as 20% in a week). The kicker is that I literally have NO BUDGET to deal with this. Any suggestions??? Patricia McElyea Curator of Collections Arkansas State University Museum [log in to unmask]
