Hi there! I thought I’d give you some information about how to care for your poured art made with .Liquitex Pouring Medium.
After it’s dry on the surface, it can stay open or slightly sticky and vulnerable to damage for a while. And, underneath, it can take a while for all of the moisture to evaporate – you can usually see a degree of milkiness while it’s drying. Sandwiched layers can take weeks to dry (think of milk trying to dry between a sealed plastic envelope), so be patient, especially in high humidity.
While drying, make sure to keep dust off it, especially if it’s exposed to heat. Exposure to heat opens acrylic molecules and it can tend to grab the dust and become one with it. This can happen with paper, or whatever pourous object is touching it. This medium is particularly susceptible to this problem.
Give it several weeks to fully cure before you varnish it. I like Golden’s or Krylon’s gloss UV archival spray varnish – less chance of bubbling than brushing it on and hardens the surface a bit. Make sure to follow the directions and keep the nozzle clean to avoid spattering, which can ruin your finish. UV protectant is a good idea, especially if you use a lot of interference paint, which can go “fugitive” on you with sun exposure.
I still suggest using care when handling it or storing it, if it isn’t going to be hung on your wall right away. The medium never really goes as hard as a resin, and you want to protect it from dings and dents.
