So over the weekend I finished my “small” modular rock/hill terrain project, alas i missed the deadline I’d set myself only finished late Sunday evening… Due to higher priority’s. (Daddy duty & entertaining the wife) Anyway better late than never.
Was quite a fun but messy project, I’ll add some steps below if anyone reading this would like to try it. All in the cost for the project was under a tenner. Best places to look for the materials needed if you live in the UK I’d suggest your nearest poundland or 99p store.
You’ll need protective eyewear, rubber gloves, a face mask, a craft knife, expanding foam, filler, cheap tester paint pots (greys & whites.) Some cheap fat paint brushes, cheap black spray paint, Grease proof paper & a cardboard box.
1.) Make sure your wearing your mask, protective eyewear & rubber gloves at this time, as expanding foam is a nightmare to remove from your skin. Oh make sure your outside as well & not around animals or kids. Squirt the expanding foam into a grease proof paper lined box (if space isn’t an issue you could always use a few boxes) use the whole can as it’s a one use only. Squirt the desired amount of rocks you’d like and give plenty of space as it expands to at least three times the size. Store away for a day. I used my shed.
2.) Again make sure your using a protective face mask & eyewear, don’t worry about the gloves as it will all be dry now.
You should be able to peel your blobs of foam out the boxes, all you need to do is take your craft knife skim away the smooth skin (sound I like a ghoul) and sculpt to whatever shape you desire. Beware of small spores of foam, as on the first attempt at this I got dust in my eye, it felt like I’d gotten glassed. Flipping painful. I’d advise doing this away from other people. (go to the shed, garage or outside)
3.) Nice and easy… Slap on the filler. Don’t be stingy with it. Use your hands, get messy. Leave to dry 24hrs.
4.) Spray the rocks black, leave a few hours.
5.) Using your fat brushes dry brush the rocks. (Dry brushing is basically dipping brush into your paint & then wiping the excess off so all you are left with is a very fine & almost dry chalky residue on the brush. Then lightly skim over what you are painting. Probably best YouTubeing if your unsure).
That’s it! Congratulations you made some rocks!
