All purpose foam coat! This rock-hard cement-like coating protects and beautifies your foam projects. Comes in a dry powder - simply mix with water. It's tough but still sandable. It is inherently fire resistant. Can be used outdoors when sealed with any outdoor paint, or mixed with Boost liquid fortifier, or Bounce liquid rubberizer. Apply thick with a trowel or thin with a paintbrush. Sets up in only about 15 minutes. Extend the drying time by adding up to 50% latex paint with your water before mixing into the dry foam coat. 3lbs covers up to 30 square feet.
 
Dollar-for-dollar, our Foam Coat covers 4x as much as Rosco Foam Coat, is at least as strong, and has a longer shelf life. Plus it's compatible with our Boost, Bounce, and Grit!

MIXING: Mix in a clean container with clean water. Use 1 part cool water per 3 parts of powder (for example, 1 cup of water per 3 cups of powder). Add powder to water and mix until Foam Coat turns to a smooth paste. Do not overmix.
APPLYING: Fill big cracks and holes by applying pasty mixture with a trowel. You may add more water until mixture is thin enough to apply with a paint brush, although thinning weakens coating. Use thinned mixture to texture large areas. May be applied as thick as 3/8 inch. Try texturing surface before coating sets.
SET TIME: Use within 10 minutes. Sets hard in 30 minutes. Maximum bond and hardness in 24 hours.
FINISHING: Remove dust before painting. This product goes on smooth and can be sanded. Can be used outdoors if sealed with paint. Add Grit texturizer to create a rock-like surface effect.
CLEAN-UP: Clean tools and brushes with clean soapy water before coating hardens.

What customers are saying: "I am working on Halloween projects. This year the theme is "The Island of Dr Moreau," and I have to build an entire office and lab with and a wooden back for next year's western theme. I am using big pink insulation foam panels supported by a PVC frame. The foam coat helps with texture, stability and helps weather-proof the panels for limited outdoor use." - Kerri B., Cary, IL

What is the difference between the four foam coatings?

Here's a brief rundown on all of our coatings:

Styroplast is a brush-on plastic 100% waterproof coating. This is the best coating for retaining detail. It is the best brush on Polyurethane coating on the market. Use our syringe for accurately mixing small batches.

All Purpose Foam Coat   is the easiest to use and most popular coating. Fast drying. It is mostly for indoor use, but can be sealed for outdoor use. Just mix with water and brush, trowel, or spray on with a hopper gun.

Create Coat is a lot like All Purpose Foam Coat, but a little stronger, waterproof, smoother and whiter. It does not stick very well to itself because it is so smooth and waterproof. Just mix with water. It takes acid and water base stains better than any coating I have seen, especially when used in combination with our Stainfast stain base.

Exterior Foam Coat is stronger than All Purpose and Create Coat. It can be used in rain-or-shine and even below grade. It's gritty, but can be troweled smooth. Just mix with water. It takes 24 hours to harden and 5 days to reach maximum strength. Works very well with Stainfast stain base.

Boost liquid fortifier can be added to any of the powdered coatings to greatly increase their strength. It will also make them stick to almost any surface. If foam coat with Boost dries on your metal tools you won't be able to chisel it off with a hammer, it's that tough.

Bounce can be used only with All Purpose Foam Coat, to make it chip resistant. Or, you can make a super rubbery coating that still looks and feels like stone by adding small amounts of All Purpose Foam Coat to the Bounce to get the consistency you need.

Grit is used to add surface texture to All Purpose Foam Coat and Create Coat. It is sometimes used with Styroplast, too. It can be mixed in or worked into the surface.

Mesh will greatly increase the strength of any of our foam coats. Especially useful across seams where cracking might occur. Available in heavy and medium thicknesses.

Foam Coat Comparison Chart is a customizable guide to help you choose the right foam coat for your project.  Just check off the Compare Selected button on the foam coat you are interested in.

Our coatings have fibers and polymers that greatly increase their strength and adhesion. Products like drywall mud, that are not made to work with foam, will easily chip off.  Here is more information on gluing and coating foam:

Happy foam coating,


 

Can you coat All Purpose Foam Coat with metal impregnated resins?

Yes, that should be fine. I haven't heard of it reacting to anything. It is very inert. But it's always a good idea to make a small test first on a scrap piece.


Hello, Just wondering if you might be able to tell me if your All Purpose Foam Coat offers enough protection to allow spraying a coated polystyrene object with aerosol paint? Many thanks, Laurie

Hi Laurie,
Yes, even a thin layer of All Purpose Foam Coat will protect your foam from the solvents in spray paint. Just make sure there is no foam showing.


Could these coatings be used over paper mache? Keeping them protected from mold/water and making more durable?

We have customers who have used All Purpose Foam and Exterior Foam Coat over paper mache and reported good results. But make sure that the piece is porous by splashing some water on it. If the water leaves a dark spot it is porous enough for any of our foam coatings to stick. If it is not porous, then you can add Boost to our All Purpose, Exterior, or or Create Coat. Boost will make these coatings stick to almost anything.


I own a game store and someone (my wife) made a joking comment about castle walls and well...I'm building castle walls. My worry is that part of my walls will be near a staircase and will be susceptible to customers poking, sitting and standing on my walls.

There are many ways of going about this. Check out our Foam Artist Gallery (especially the Holiday/Haunt section).

What most foam sculptors do is carve exaggerated shapes and grout-lines into the foam, especially in the recessed areas where the foam coat will most want to fill in.  Apply a thin coat for looks where the foam walls won't be touched. Apply a thicker coat (like, 1/4") where it will be touched. And even thicker (up to 1/2" where people will be walking on it. Where people will be jumping on it, and along any seams and corners, you might want to use Mesh.

Applying multiple thin coats and using a hopper gun will greatly help retain detail. Start at one end and by the time you get to the other end you can spray the first end again. Keep repeating this process until the foam coat is as thick as you want it. 

If you are brushing it on use a big stucco brush. I like to apply a thin scratch coat with Boost mixed in to start things out as this will give the next thicker coat something to grab onto. Since Boost strengthens the foam coat you don't have to put the foam coat on as thick, so it is useful in retaining detail.

All Purpose and Exterior Foam Coat are very forgiving to use and can be coated over and over, so you really can't go wrong.

I have done foam sculpting for over a decade and nothing revolutionized my work more than Hot Wire Foam Factory's basic hot knife sculpting tools and All Purpose Foam Coat. I have found Foam Coat to be easy to use and the ideal way to simply create a variety of textures while giving strength and durability to my creations. It can be mixed thick or thin depending on the need and accepts paint very well. I have used it successfully with objects such as branches, fossils, grass, etc. embedded as decorative elements.
One of my clients is a zoo where I create naturalistic elements such as rock and tree sculptures. After discovering Foam Coat I was able to create interesting environments for the animals in the indoor exhibits instead of just the outside decorative work. This made for a more immersive experience for the guests and an interesting environment for the animals. A stone worker, there for a visit, warned that the "rock" over the glass was too heavy and would stress the glass too much!
Since I also create dinosaurs for a fossil museum I really appreciate the fact that I can make creations in sections and after transport I can blend the parts together seamlessly since the product will blend wet on dry with little effort. Just a bit of wet brushing does the trick. It appears not only seamless but provides the necessary strength and rigidity to support a large sculpture.
Multiple times I have had clients tell me they'd like an interior wall to look like natural rock, but can't afford to have it done. I have shown then how to create the look for very little effort and money using All Purpose Foam Coat.

My company Fantasy WaterWorkz does indoor/outdoor above/below ground ponds & waterfalls. what makes my creations different is I start with a base of Styrofoam. YES I said Styrofoam. You know the stuff with the breathable holes in it! I was going to use plaster to coat it but decided to try this Foam Coat. I was IMPRESSED!! It applied easily to the styrofoam and gave me a finished product that was more stable and harder than plaster. This company's products are a must try for any project!!

We have been building props and costumes for about 4 years. We use a variety of materials including EVA foam and pink insulation foam on many of our projects.

A problem with using pink insulation foam is that it is very fragile and many paints and adhesives eat through it. Once the foam is sealed with All Purpose Foam Coat, the foam has additional strength and is now safe to paint and sand.

We built a large 10' tall Reinhardt axe (From the game Overwatch) out of insulation foam and were able to keep it light weight and add durability by using the Foam Coat.

We liked that you could mix as much or as little water into the Foam Coat in order to patch dents and imperfections in the foam. We also liked that we could sand the foam coat to get a smooth finish before painting. We will certainly be using this product again in future projects!
