Polyfoam lined latex?

Hi. In the video, Tim said he lined the inside of the latex mask with polyfoam. Is that just a general polyfoam he used? How do you line the inside without filling it completely?

    Hi Chris,

    Any polyfoam will work, just as long as you select a density that works for your desired application.  Denser foams will be heavier and less flexible.

    There are 2 main ways to line the inside of a mask with polyfoam.  The easiest way is to brush the foam along the inside surfaces of the mask evenly.  As the foam expands inward it will leave a hollow core.  You can do this in small batches to get the desired thickness if a single brushed on coat is not thick enough for you.  Different foams have different expansion amounts, so your mileage may vary. 

    The other way is to suspend a core inside the mask and pour polyfoam around it.  This is a bit more complex, mainly because it requires some type of core.  It's also a good idea to put a lot of release agent on your core so the foam does not bond to it, and to help make it easier to remove.

    I would go for the brush on method.  It's similar to rotocasting/slush casting, just with foam.

    Hope that helps!
