View Full Version : Best way to hard coat styrofoam?

06-19-2009, 09:10 PM
What do you good people of HauntWorld think is the best way to hard coat styrofoam walls? [and for the record, that's where we came up with the silly name BarbieHaunt - it's just our private joke name for the haunt while it's being built because it reminded us of a Barbie Dream Haunt with its pink styrofoam walls before they are hard coated and painted]. Thanks in advance for any help you are willing to give us.

As the recommendations come in, I'd like to add a few questions.

1) Is there different recommendations for indoor vs outdoor?

2) Is there different recommendations for things audiences will likely come into contact with vs stuff they won't?

Don't know if you saw THIS thread: http://hauntworld.com/haunted_house_forums/showthread.php?t=7470

It links to the product here: http://www.volatilefree.com/qwik_spray_system.asp

It really depends on what HauntedMemphis was saying. Big outdoor facade? Probably worth investing in one of the systems like the Qwik Spray System or the one from Industrial Polymers. Something inside that customers may come in contact with? Probably either one of the mentioned systems or even a stucco or cement material. A display thats set back and won't get much abuse? You could even get away with the hard coating material from the Hot Wire Foam Factory, which hardens the foam and keeps it from chipping off. It can take some abuse but I wouldn't push your luck with a whole seasons worth. So I guess it really depends on what your looking to do with it. And be sure to check out that other thread, it should point you in the right direction.

This stuff is great it will totally water proof your styrofoam and anything else. It is great to use on headstone. You can get it at any lumber or hardware store. I buy it in 1 gallon cans they might sell it in 5 gallon buckets but I am not sure. The product is called Drylok. It is used to coat basement walls to prevent water damage. You paint this on. It workd great!!

Wow! Thanks, everyone, for all of the helpful information, including the link to the other thread with all of the other links! We're going to get together and figure out which way is the best way for us to go. Thanks again!

Is Drylok a sealer or does it also hard coat the foam? Seems like just a sealer and would not protect the foam if someone hits it or bumps into it....

Inspiring, thank you. I'd really love to visit your haunt if I have the time this October.

Hello Barbie,

Any update on you coating your haunt foam? Any pics? If you kept it pink with creepy Barbie’s everywhere I could see that scaring the crap out of people.

Scary little dolls….People would never buy them again…Ha ha ha !
