Thread: Grime up Props and Everyday Items

Tweet

Here's a way to take the brand new prop you made with new materials and dirty it up so it looks like it's covered with years of grime. This also works great for everyday items you use in your haunt to help them blend in.











Pictures that compliment the video:

The amp on the left looked like the amp on the right.

The colors used are grays, rusts, green, brown, white and black. The black is straight paint with no drywall compound added. Any acrylic gloss varnish will work to add shiny spots on your prop for that slimy look.

You can make small batches of colored monster mud using those small jars of drywall compound from the hardware store. For very thick monster mud good for thick accents mix a brimming 1/2 cup of paint (5 oz) with the one jar of drywall compound. This is a 5 to 1 ratio. The original paint color will lighten significantly so bear that in mind. The more paint you add, the thinner the mm. Thinner mud is good for more overall coverage like what was used for the medium gray and medium rust in the video. That ratio is about 3 parts drywall compound to 1 part paint. All of these ratios are flexible and you will discover what ratios you like to work with for the effects you are trying to achieve.

For larger batches of colored monster mud, you could get one of the large buckets of drywall compound and divvy it up into 3 or so colors. Get some empty 2 gallon containers from the hardware store to mix and store.

Trash can Trauma made extra grimy.

My computer controls the haunt and it's right in the room so I gave it a costume.

Quick transformers from plastic trash cans.

This was a black amp made moldy-looking. It's the speaker for a prop so this helps blend it into the scene.





Thanks so much for looking at my tutorial

Very Cool!!!!

Thanks a million for that, lotsa useful tips!

Nice job T

You are so AWESOME,will you marry me????Kidding,I wish my wife was into Halloween half as much as you are.Keep up the great work,big fan..

That tutorial taught me tons! Thank you for posting.

Wow that looks good if you can permanently do it to your things.

Nice work. That red amp was hideous!

Well done. What is interesting is I am refinishing my guitar cabinets because they look like your finished effect after years on the road.

How did you do the transformers? What are the top pieces made out of?

This is great, I'm going to try this out on some of my props.

Glad this could help. It's a LOT of fun too Just finished griming up some PVC piping and turned out great. I'll try to get some pictures up soon.

Here's a picture of the transformers while being made. It's a cut up pool noodle (cut at an angle) on PVC. I also used car model wheels for nuts and a really mutilated pool noodle for really large nuts. Styrofoam for the weird thingy on the side, some plumber's strapping and metal strap for other nick knacks to help make it look tranformy... The final touches were unraveled thick manila rope for wiring, stick-on bullet holes, 220 volt sticker (thanks Diabolik!) and a battery operated strobe light.
