Heres my latest project. Built from PVC frame then Spray foam (no chicken wire) paper mache then paint to match the mask and have green LED eyes. Should go good to match my sewer monster.

Does anyone know of a good way to protect your paper mache from rain? On some of my stuff I have used Tompsons water seal but it never "dries" it protects it from the rain becuse it bubbles the rain but whenever I move it, its sticky.

OMG that is freaking scary! Nice reptile skin and like the eyes a lot. Hope to see more photos as you finish the creature. Definitely hope you get him protected because it would be a shame to have him damaged.

That is amazing work - I'd have never guessed it was home made out of paper mache and foam!!

There are clear coat protecting coatings (I've seen spar urethane suggested I think) that might work. They seem to only come in gloss, but there must be a matte finish around somewhere. Also maybe Scotchgard for outdoors (UV and waterproofing protector in spray can)

BUT for that prop, I'd want to get a test subject and put it out for a few weeks before jumping in and coating it with anything untried. I'd hate to see it ruined by the very thing supposed to protect it, or see it fail after a week's exposure! So suggest building a very simple test prop using the same materials (but without the amazing details) and stick it outside for a while? Definitely would want to coat the test subject with the same paint and whatever so you can be sure it won't destroy the actual prop in application.

Looks amazing:)I have tried a few different things and I have found Yacht Varnish worked best for me. Some of my props have really took a battering with the UK, but they have been ok. Again I would test it out on a small patch first, just in case

For my last 2 paper mache creatures (Devil Dog & Ground Sewer Monster) I made the form with chicken wire but I thought after I was done it made them fat instead of skinny starving scary.

I set up my halloween display the day of and take it down the same night (to prevent thieves) so the creature wont be out for a month at a time or so but for the last 7 years it has rained on Halloween for me.

Wood stain Floor Solvent Pattern this is what I have used to waterproof my paper mache, works great to repel water but its always sticky.

What is the difference between Drylok and the spar urethane?

Also, I am planning on having foam graves out for the whole month. They will have multiple coats of house paint on them, but should I put some type of additional waterproofing sealer on at the end?
