I have a plaster of paris statue that I keep outside, but the weather is eroding it, is there something I can coat it with to protect it from rain and weather, and then can I paint over it? THANK YOU

First thing I did was to get it out of the rain. Unfortunately yard art gets worn by the elements. A coat of poly might help. But that would only slow down the erosion.
"Outdoor plaster statues are used to adorn gardens and lawns of several homes. Unfortunately when plaster becomes exposed to humidity and moisture it can begin to degrade and pieces of the statue will eventually begin to fall off. It is possible to waterproof an outdoor plaster statue in order to preserve it and protect it from the elements for several years to come."

Have you considered moving your statue to where there is less exposure to weather?
Poly would be a good temporary protector. When it comes time to paint, a waterproof masonry paint would be best.
Plaster of Paris is very porous and not the best choice for outdoors. Try sealing it with polyurethane or waterproof masonry paint.
I have used 2 things on my yard statues, one which worked very well was to spary it with several coats of Lacquer, the other was to coat with Thompsons water sealer.
Plaster of Paris isn’t meant to withstand outdoor weather unfortunately. If you can move it to a dry spot, that will help. You could try sealing it then using a skim coat concrete over it, then sealing that.
Hi Debbie: Perhaps this site will help: How to Seal Plaster of Paris - Easy POP Waterproofing Guide! (paintstrategies.com) or, maybe this one: How to Waterproof Plaster of Paris | (With 5 Useful Tips) (diywaterproof.com)
Good luck
Maybe a Glass case? Plaster of Paris is very pourus and would need to be sealed with mybe Yatch Varnish a few times to make it water proof.
Plaster of Paris remains to a degree water soluble and slightly 'chalky' so it will be eroded by wind and weather. If you want to experiment you can try covering the piece in varnish or Shellac but that won't last for a very long time.
