Styropoxy / Re: Spraying Styropoxy
Last post by HotwireDirect - August 27, 2013, 10:06:44 AMHi Imageres,
Even though we have not found a great way to spray large quantities of the Styropoxy 7015 and 7060 at this time, it is spray-able with a gel coat gun found here:
http://www.fibreglast.com/product/Gel_Coat_Cup_Gun_00120_A/spray-guns-and-equipment
The 3/16" I/D opening is perfect for the Styropoxy as it's very thick. You also need to hold the gun pointed to the ceiling if you are not actively trying to spray as the material can drip out the large orifice otherwise.
The thing is from tests it was producing the most smooth molds when you brush after spraying. Two coats (brushed each time) produced the finest results.
So for some users the spraying becomes redundant and only makes more clean up than needed. For others it is a good way to apply it. I'll leave that call up to the users.
In tests with other gravity feed HVLP guns it was possible to spray, but it applied the material so slowly it may aggravate the user and test their patience.
One sure way to apply it is to mix and pour evenly across the foam then spread with brush. I typically use the disposable brushes, but it will clean up with Acetone, Alcohol, or warm soapy water if you want to reuse your brushes.

Styropoxy / Spraying Styropoxy
Last post by imageres - August 26, 2013, 11:17:55 AMI am looking for some guidelines on using a sprayer to apply Styropoxy for mold building. What type of sprayers work best and where can they be purchased; and general techniques for application. What I am looking for is an application method that will produce a smooth finish without a lot of hand finishing.

Show and Tell / 8300 Extreme Tapers Video
Last post by HotwireDirect - February 17, 2011, 08:55:14 AMFolks,
Here's a rough little video of the 8300 doing a very steep tapered cut in high density (2lb) foam.

The ability to move each end of the machine is one nice thing about the 8300 because it allows for 16'+ monolithic cuts as well as these tight little tapers that aren't possible on fixed towers.

Show and Tell / Decorative Concrete Columns Mo...
Last post by John - October 05, 2010, 01:17:53 PMHere's a project I did recently (Summer 2010) for a decorative concrete shop. They needed the molds for a set of 8 concrete columns for the front of a clients house.
The column was a simple straight taper (kind of looked like a craftsman style with such a pronounced taper, but it was 8' tall) and it was a simple multi-axis cut. The foam was then coated with Styropoxy for multiple (4) pours for each mold.
The capital and bases were made as positives on the turntable and will have rubber molds made off of these models. The capital and bases were patched as needed with a lightweight interior-exterior Spackle compound, sanded, and coated with Styropoxy.
I'm waiting to hear back from the concrete shop for photos of the finished work, but I'll try to get some photos to post if I can.

Show and Tell / KMG Projects II
Last post by kmg - January 21, 2009, 07:37:15 AM1) Raft used in a photo shoot for a magazine
2) Cross Prop 12 ft. tall 10" Diameter
3) 8 ft. tall bell used in a Christmas Program. Bell was 10 ft. diameter at the base, and was also 2 sided. THe bell was on a turn table so it would rotate during the show to reveal a live manger scene on the other side. The painting, coating, and design was all done at our facility by our company.
