I normally paint with drylok which works awesome
You need a sealing base coat first. A coat of primer like Drylok or Kilz works, or just any light colored latex paint will do. You can check your local paint stores and big box stores for discounted paints and mis-tinted paints for cheap.How do you spray paint Styrofoam without it melting?
This looks great. Nothing like home made stones in comparison to the over priced crap sold at the Halloween stores. I had an "Eileen Dover" stone as well, coupled with "Ben Dover". The funny names are always a crowd favorite.. You got some nice aging and streaking on this too. Nice job!
