Hi again gang,
I’m working on my latest cue case and after designing and building a custom jig, I was able to hot knife (out of Styrofoam blocks) tapered troughs for the pieces of the pool cue! In the past I did something along the same thing but I passed the foam over the hot knife.
The problem I discovered is applying a fabric to the foam is not a big deal when the trough is the same shape and depth from one end to the other. But now that is different and I’m foreseeing problems. I need this to look very professional so no wrinkles.
The Styrofoam is not high density but still pretty smooth. I’m thinking of using Flocking for the first time.

My questions are:

1. Will the adhesive eat the Styrofoam?

2. Will the flocking hide the super small imperfections in the material?

I don’t know if you guys have tried Flocking in this type of application but it’s worth asking!

Here is a few pictures of my jig and what I made. Notice the difference in the depths from one end to the other.

Thanks!

Are you talking about the spray on flocking, or the psa stuff.

I didn’t know there was 2 kinds!
I found a paint on adhesive that you “puff” on the flocking.

You can go to just about any fabric store and they will have felt with a pressure sensitive adhesive on the back.

I have concerns on how well that would stick to Styrofoam.

I just searched the web and the adhesive for flocking is just Acrylic Paint and is fine for working with styrofoam! So my only question is Do you get a professional finish with the spray on flocking?? I have a 6” x 32” area I need to cover and I need to to hide the texture of styrofoam. I’m using black flocking if that matters.

Try both and see what works best for you. You could seal the styro first.

Seal it?
How??
I don’t want to make it brittle or give it a hard shell.

What about an acrylic paint, or something like that.

I do flocking on cedar and use acrylic paint and the puff-on rayon. (Oil paint also works) I need to thin the paint a little and put the paint on very thick to avoid brush marks so I think you would want to smooth out the stryo foam before flocking it.

Bill,

What I would do for smoothing is to get yourself a can of bondo from an auto parts store. Skim coat it on, and sand it smooth. Then apply your flocking on that.

J,
I thought about that but the whole idea of me using Styofoam was to have something soft with a bit of give to it. I have lots of experience with bondo and that would crack and break off if flexed.
I’m tossing around the idea of covering the flat surfaces with nice fabric and just flocking inside the troughs.

I have not worked with Styrofoam so I am not sure how to fill in the voids on the surface. Some flexible glue maybe? Leaving it rough will give you a rough surface after flocking so I would experiment with some filler. White glue maybe? Fabric glue?

What about white gluing some very sheer fabric to the styro. squeegee it down and then apply the flocking. I still thing the felt with the adhesive is the way to go.
