Can you use playdough as a resin mold?

I wanted to know if I could use playdough as a resin mold. It’s supposed to be so hard to get the perfect shape for your resin piece, and I’ve tried so many things without succeeding. Playdough is cheap and easy, but will it work? Here’s what I found out:

Can you use playdough as a mold?

Epoxy resin is a great material for making molds. It’s versatile, easy to work with, and can be used to make nearly anything you want. You can even use it as an adhesive in your projects—which makes it especially useful in the kitchen.

But before we get into the process of using epoxy resin as a mold, let’s talk about what you need to do first:

  • Make sure that the epoxy resin is compatible with playdough (you don’t want your hard work ruined by bubbling or breaking apart!)
  • Make sure that your playdough is smooth and not rough (you’ll have trouble removing it from the mold if it sticks).
  • Make sure that there isn’t too much playdough on top of each other so they won’t stick together when drying out (this will happen if they’re thick enough!).

What can I use as a resin mold?

To make a mold, you will need to choose a material for your mold. In general, any material that is porous and can be formed into the shape you want will work. The most common resin mold materials are silicone, latex, and plaster. Each type has its own advantages and disadvantages when used as a resin mold.

Plaster molds are easy to create but have the drawback that they do not last very long because plaster absorbs moisture from the air over time which causes it to become brittle and crack or break apart.

Silicone is much more durable than plaster but requires more effort in preparation due to its stickiness during the casting phase before it cures completely (usually 12 hours).

Latex is somewhere between these two materials in terms of durability but does not require any special preparation steps before casting with resin

What can I use to make a mold for epoxy resin?

The first thing you need to do is decide which materials you want to use. You can make a mold out of silicone or use a pre-made one. Silicone is easy to work with, but it’s not resistant enough for some types of casting.

If you’re using epoxy resin, however, silicone will work great!

If you want something that’s more durable and long-lasting than silicone but still easy to work with and relatively cheap—and if your project requires an accurate reproduction—you might consider making or buying an existing mold instead.

This may be the best choice if you want a lot of flexibility in terms of what kind of objects are made from the casting process (as opposed to simply being able to make multiple copies).

Can I use cardboard as a resin mold?

Yes, you can use cardboard as a resin mold. However, there are some things to keep in mind when using this material as a mold.

First off, be sure that the cardboard is thin enough to bend easily but thick enough that it won’t warp too much during the curing process.

The cardboard is not very durable and can tear easily if too much pressure is applied while forming the box or mold. You also want to make sure that there’s no wax paper or plastic wrap between your object and your cardstock because this will cause bubbles and other unwanted effects when casting with resin.

Will resin stick to play dough?

You can use playdough to make molds for resin, but there are some things you should know before you begin. Playdough is a great material for molds because it’s easy to get out of the mold once it’s dried and hardened—but that also means that if you don’t take care when preparing your mold, it will be harder to remove from the resin later on.

If you’re planning on making more than one piece with this particular playdough/resin combination, then consider using something else as your base.

You’ll want to make sure that you’ve got plenty of ventilation during this process too; while using playdough isn’t dangerous per se (unless maybe the dog gets into it), fumes can build up over time and cause respiratory issues if there aren’t any holes in your oven door!

The best thing about working with play dough is its low cost compared with other materials such as silicone rubber or plaster—you won’t have spent much money buying supplies either way though since most people already have to access to some form or another within their kitchen cupboards.”

How do you get playdough out of molds?

Once your molds have cured, it’s time to remove the playdough. You can use a knife or spoon to cut out the playdough if you need to.

Sometimes, though, you’ll be able to pop out a piece at a time. If that doesn’t work, try using something like a toothpick or toothbrush as an extra tool for cleaning out the mold.

What will resin not stick to?

Resin will not stick to silicone.

Resin will not stick to wax paper, plastic wrap or aluminum foil.

Resin will not stick to PTFE tape (that’s the stuff they use in non-stick frying pans).

How can I use resin without mold?

If you’re aiming to create your own resin piece using a playdough mold, there are several different ways you can do this.

  • Use a silicone mold. Silicone molds are best for beginners because they’re reusable and won’t stick to the resin or your object once it has hardened. You can buy them online or at craft stores like Michael’s (and even Dollar Tree!) or make your own with food-safe silicone from Amazon. In addition to being easier to use than cardboard molds, they give off less odor when heated up in an oven and have smoother surfaces so that details will come out clearer on both sides of the finished piece.
  • Make your own cardboard mold by cutting out shapes from regular old corrugated cardboard (like this one). This option is cheaper than buying an already-made kit but also requires more effort on your part: cutting out each shape individually means there will be gaps where air could escape; keeping these closed while heating up in an oven may require extra materials like tape or glue; removing air bubbles after pouring takes some finessing as well—you might need something like needle nose pliers!


resin crafting is a great hobby, and the sky’s the limit when it comes to what you can make! Whether you’re looking to create a custom keychain or make unique jewelry pieces, resin will allow you to do so much.
