we made plaster of paris reliefs of the grandkids. Is there a way to seal them so we can use them to decorate in the flower gardens
handprint reliefs we want to preserve
you can use outdoor plaster next time round. but they would last about one year if you seal them with varnish.

I will have to rephrase my sentence if you use ordinary plaster it will only last a year with varnish but you can use outdoor plaster that will last a life time
