Can you use playdough as a mold for resin?

Hey there! So, you’re curious about making your own molds for resin? The answer is technical, yes, but it’s a little more complicated than that.

Before we dive into the details of using playdough as a mold for resin, let’s go over some FAQs to get you started.

Can I use play dough for a resin mold?

Can you use play dough for a resin mold? Well, that depends.

  • Play dough is not a good choice because it is too soft and will probably melt when you put the resin on top of it.
  • Play dough is not a good choice because it is too hard and will probably crack under pressure from the resin pouring over it.
  • Play dough is not a good choice because it’s sticky and might stick to the mold—and stay there forever!

What can I use as a mold for resin?

Resin can be used to make practically anything, so you can use just about any object you want as a mold. If you’re making a plastic or metal sculpture, try using an existing object such as an empty plastic container or metal cup to create your mold.

Plaster of Paris is another great option because it’s easy to work with and inexpensive. To make this type of mold, mix plaster powder with water until the mixture has the consistency of peanut butter (which is not too runny).

Then pour this into whatever shape you’d like and let it dry overnight before removing it from its original item (like a bottle cap).

This will leave an impression that can then be filled with resin for casting purposes!

Can I use hot glue instead of resin?

You can’t. Hot glue is not a good substitute for resin. It can be used to make molds, but it isn’t as strong as resin and won’t hold up to the same temperature or pressure.

Hot glue doesn’t have the flexibility that makes resin such a useful material! If you want your mold to be flexible and easily usable by yourself or others, you need something more like hotmelt plastic or rubber cement—but even then, these materials are not suitable for use with some types of resins like polyurethane and epoxy (more details below).

Can you use painters tape for epoxy?

Painters tape is not a good choice for epoxy. It doesn’t stick well to surfaces, it isn’t flexible enough and it isn’t waterproof.

Painter tape is made of paper or cloth with a rubber-based adhesive on one side to keep paint off of walls while painting.

The pressure-sensitive adhesive will stick well to the surface at first but will peel up if there’s any pressure applied in the opposite direction.

Painters tape also has many other problems when used with epoxy:

  • It can’t be stretched over curved surfaces easily
  • It’s difficult to remove once cured (though this could be solved by using fewer layers of epoxy)

How can I use resin without mold?

Resin is a two-part liquid that hardens with exposure to oxygen. This means that you can use it as a mold by pouring the liquid into an object and letting it dry, then removing it when the resin has hardened.

You can also use this technique to make jewelry or other objects with low melting points, like chocolate. Resin is used in industries such as prosthesis manufacturing and dentistry because of its ability to make models of body parts that are more durable than wax molds would be.

How do I make my own resin mold?

If you’re looking for a natural alternative to silicone, you can use playdough as a mold for resin. The key is to make sure the play dough is completely dry before using it in your project.

When making your own resin mold using playdough, remember that not all types of playdough work equally well.

If you’re using colored or scented varieties of dough:

Make sure the color or scent is completely dry and does not interfere with the curing process.

Color dyes may have an adverse effect on the adhesion and durability of your finished piece; avoid these types of molds if possible.

How do you make mold out of household items?

The first thing you’ll want to do is find a flexible household item that can be easily removed from the mold.

For example, a plate or bowl could work, but not if it’s made of glass. You will also want to make sure your object is not porous because this will affect how well it can be cleaned and how it reacts with resin.

It’s important that the material you use doesn’t stain or react with the resin when heated (for example, aluminum foil may light up when exposed to heat).

Does resin stick to Silly Putty?

  • Use play dough as a mold for resin.
  • Hot glue can be used instead of resin, but it’s more dangerous because it gets hot and you’re dealing with glue sticks (which are flammable).
  • Painters tape for epoxy works well if you want to make sure that no resin leaks through the seams of your mold, but this method is not recommended for beginners because there are so many variables involved in making sure everything goes smoothly when using epoxy molds like this one which could result in wasted material (and money).
  • You can use household items like plastic cups or aluminum foil if you’re going low budget while still trying out new materials at home; however, these methods aren’t recommended since they have low success rates compared to other methods we’ve discussed today such as using playdough or hot glue as a means towards creating something beautiful with ease!


So there you have it, if you have the time and the patience to experiment with different materials, then you can make a mold for your resin. The best part is that it’s super easy and fun!
