Why forms will save you Time + Money

On the market there has yet to be a 'perfect form' that will suit 100% of your needs.

Each design has it's Pro's + Con's and it's a matter of choosing one that will best suit your needs based of the tools you own. This being said, there is no question that purchasing a form will save you time and money vs building your own form before each project you make!

Key Facts

There are so many different resins on the market. You may be tempted to get a cheaper brand however, this could cost you in the end. Using less reputable brands increase your chance of having your project stick to the inside of your form (Even with the use of Mold Release). We recommend Squid Poxy or Ecopoxy brands as well, using a mold release inside your form before each project to ensure no issues. 

Building your own form

Pro's: 
- Custom build to your project size with no waste around the edges

Con's:
- Has a limited lifetime for multi use as the Tuck Tape wears out over time
- Spend a lot of time assembling the form
- Risk of Resin leaking from the seems if not properly sealed with silicone

Use this Mold Release on both of these forms to prolong the life span of them.

Silicone Forms

Silicone forms area a great option for DIY Resin projects. There are lots of different kinds on the market, so make sure you get one that has thick walls which will guarantee multi-use out of one mold. When the silicone has thin walls, you will run the risk of the material breaking down when taking your project out of the form.

We highly recommend not to use any Mold Release on these forms
