So this stuff doesn't eat Styrofoam?
That is correct.
What do I add to it to make it set?
Nothing, it is an air-dry system. No catalyst is needed.
How long does it take to dry?
Four and a half hours in our dry-desert heat. The second coat takes less time for some reason.
No harmful fumes?
No, its as harmful as common 100% acrylic house or craft paint.
Is it dangerous?
Yes, if misused just like anything else. Please don't eat it, drink it or swim in it.
Wear gloves and eye protection. I read one study where Styrene is linked to cancer. My
product does contain liquid styrene. EPS is styrene. Right now there is only one study
out, we'll need to wait for more tests to make sure the theory is correct.
Do you still have Vanillacryl?
No. We stopped selling it several years ago because we couldn't depend on our supplier. That forced us to develop Steve's Foam Coat.
So what's the difference between Steve's Foam Coat and Vanillacryl?
Chemically these are different products. It's not known what is in the Vanillacryl but
SFC is an acrylic base. In terms of product the Vanillacryl was weather tested and works
great for outdoor signs, it did not shrink, was hard as promised. I still recommend it if
you can find it. SFC is more expensive, it does shrink a little and takes paint very well.
Can Steve's Foam Coat be used outdoors?
It's not been weather tested but we've had many customers who have used it outside. I
just doesn't have a track record for outdoor use. We spilled some in my truck two years
ago and it held up just fine for about a year. I'd say paint it with a good outdoor
primer/sealer and don't make promises you can't keep.
Whats the best way to paint it?
A spreader, then a fine brush. It can't be rolled. Some people have sprayed it but it took some real experimentation with a Heavy Body Sprayer.
What is it's coverage?
One gallon will give you about 50 square feet, one coat, .040? thick.
Can I texture it?
It has some body and some texture I can best describe as Cream-o-Wheat. If you just
want to take the surface out of the EPS use our Retexuring compound, which can be sprayed.
So I can't get it smooth, right?
Yes, if you are good with a spreader. It can be sanded, but that is a lot of work.
I can sand it, right?
Yes, but this stuff is really hard. Imagine painting your EPS with a layer of oak or
maple wood. I use the biggest grit of sandpaper I can get, like 40.
What do you mean when you say it shrinks, isn't that a good thing?
Up to a point. If you have long skinny strips it will bow them. Use the Re-Tex or
Fiberglass version instead. Shrinkage is good when you really want something to be
strong, but that something has to be a fairly big or strong block of foam.
Can it be painted?
It was designed to be be painted. It actually takes paint better than paper. It's natural color is sort of a natural creamy white.
Does it come in colors?
Nope, not needed. If you want to color it you can do it yourself with the water based
tinting agent you get at the paint store. You can also use the artist's acrylic paint you
get in the tube at the art store.
Can you build up the layers?
Yes, as many as you want, it just becomes a thick, strong layer of plastic on the surface. Very strong.
Is it as strong as fiberglass?
I don't think so. Epoxy and polyester are very tough resins. You can use the SFC like
you would use polyester resin in fiberglass. remember that the strength in fiberglass
comes from the glass fibers not the resin, the resin just holds everything together.
So let me get this right, I can use the SFC like I would use common polyester fiberglass.
Yes, but my stuff doesn't stink. Use it to laminate the glass cloth or matte just like any other resin.
