Needing help with a project I'm wanting to try using mastic with cookie press/gun

[MagickMuffin]

This is an art project that involves using mastic. I was wanting to make designs using a cookie press that has different type plates of designs. I tried just using the mastic but it wouldn't stick to the paper. I then added some baby powder thinking if I somehow thicken it up that it would come out better, however, it didn't work either. I was thinking of adding some of my paper pulp, but haven't tried it yet.

Anyway does anyone have any suggestions that might work. Once I finally accomplish this task I plan on attaching the designs into wet mastic.


Here's a pic of the cookie press/gun. Mine is a lot older than this one and don't mind using it, I have a battery operated one but don't want to use it for this project.

1. Does it have to be mastic

I was thinking that joint compound might extrude easily. It might be too thin. But there are other types of thicker wall repair materials that might work and clean up quickly from the cookie gun. Sticking to the paper is tricky. But I've seen examples of wall designs made with joint compound and stencils. If it sticks to a wall surface, it might work for paper that has a texture to help the gripping.

2. i agree that joint compound might work, although

the shrinkage that you get with it might not be good. using a dry one, and mixing it thickly might work.
i learned a trick about this from plasterers i had here earlier this year- prime the surface. i was surprised to see them prime the whole room before they started a skim coat.

6. I'll have to see if I have any JC around here

I don't think shrinkage would be too much of a problem for what I'm want to accomplish.

Thanks for the info :)

4. Well I already have a pail of mastic available, not sure if I have JC

Perhaps I could add some joint compound with the mastic and see what happens. Wish me luck :)

Thanks for the input, eleny

3. You gave me a great idea about how to fill the cracks in the

old stone foundation of my house. Every time I tried to use a trowel to mush the cement into the cracks, most of it plopped onto the ground. If I shove the goop into an old cookie gun, I could aim it where it needs to go. Now to find an old cookie gun. Yard sale, hopefully.

PS, if you need something that will dry hard as a rock, the furnace cement I just used(see old post) is great. Easy to work with, a little dryer than joint compound. A bit pricey but for my purposes it was fantastic.

5. Instead of a cookie press/gun, you should try a pastry bag

you would probably spend less money, and it would also have a better control of aiming it in the cracks.

Thanks for the tip :)

7. or a grout bag

little sturdier that a pastry bag. they sell them at home depot. less than $10, iirc.
