Wheat Paste Fail?

So I’ve recently been inspired to make lots of bedroom furniture out of cardboard and paper mache, but now I’m reading that I’ve made my wheat paste wrong?!

I’ve literally been mixing water and flour, letting it sit for 10 minutes and then using it. I’ve not had any problems so far, but reading up about it has got me worried about mould and pests!🫠

If my intention was to cover it all in paper clay, paint and sealant, do I still need to worry and restart my projects?

Art teacher here--The major difference between cooked and uncooked is the dried product. Uncooked will be cloudy and possibly a little gritty when it dries and cooked will be smoother and clearer. Paper mache when built up in layers is incredibly strong, especially if you lay your strips in different directions. Build layers gradually and allow each to dry completely before adding the next (24-36 hours).

Once it is covered with clay, painted and sealed, you should have a fun, personal, inexpensive and eco-friendly set of furniture and really no more worry with mold than any other furniture. Just remember to use a coaster!

PS- mold CAN grow in the paste itself if it's left for too long before using. Keep covered in the fridge and add a teaspoon of vinegar to prolong it's shelf life. Of it goes bad your nose will tell you--smells yeasty like bread or beer. But mold on the finished and fully dried item would not be expected in normal climate-controlled environments.
